Definitions

  • High solids coatiftgs for the purpose of the present invention shall mean organic coating compositions in which the organic volatile solvents of the coating are minimized by the substitution of a reactive diluent and/or a reactive solvent for all or a part of the volatile solvent or diluent usually employed to make useful coating compositions from a particular film forming polymer.
  • the coating composition may be of two types: (1) stable dispersions of an organic polymer in an organic diluent (so called NAD or organosol), (2) solutions of organic polymers in organic solvents. It is the intent of this invention to disclose the preparation of high solids coating compositions which utilize at least one organic, non-volatile substituted, reactive carbamate which is also a solvent or dispersant for a film forming polymer to replace a part or all of the thinner required to reduce the coatings formulation to the required applications viscosity.
  • Reactive solvents and reactive diluents as used herein are nearly non-volatile organic materials which have as an integral part of their structure a plurality of functional groups which are co-reactive with the base film forming polymer and/or required crosslinking agents, and can replace a part or all of the volatile organic solvent and/or diluent required to reduce the formulation to a reasonable application viscosity. They may be liquids or solids providing, those which are solids are soluble, fusible, and compatible with the film forming components either before or after application and subsequent cure.
  • Adoption of this definition imposes some requirements on materials which can be considered as reactive solvents and reactive diluents. They must be: (1) essentially non-volatile under the conditions required for cure of the coating, (2) good solvents for the film forming polymers or in the case of the dispersions, be temporary plasticizers for the base polymer during film formation, (3) latently co-reactive with the film forming polymer and/or the cross-linking agents under conditions required for polymer conversion, and finally (4) be able to provide final film properties required for the intended application.
  • the properties of the coating are related not only to the properties of the film forming polymer but also to the properties attained from the reactive solvent or reactive diluent upon chemical incorporation into the composition. Often it is necessary to adjust the structure of the film forming polymer to compliment the structure of the reactive diluent.
  • Such polymers are designed for this intended use, and are preferable to polymers used in much of the prior art.
  • polymers of the prior art can be formulated, using reactive diluents and/or solvents, into coating compositions with lower emissions than the corresponding formulation of these identical polymers using only volatile non-reactive solvents and/or diluents.
  • FIG. 1 is a simplified phase diagram of a hypothetical dispersion high solids coatings system, representing the volatile diluent as A, the reactive diluent as C, and the film forming polymer including the cross-linking agent as B.
  • the area of a single phase, 2 is separated from the area of two phases, 4, by the curved line A-A'-B.
  • the point E represents the application composition of the high solids dispersion coating.
  • the straight line E-D represents the changing compositions during film formation; the dashed line E-B is the film forming pathway that the high solids coating of the prior art would take, in the later case the diluent C' is the fugitive plasticizer required for particle coalescence and must be removed from the film by vaporization otherwise performance properties would be degraded. In the former the reactive diluent remains an internal part of the film and is incorporated into the polymeric film by reacting with the polymer through the reactive functionalities provided.
  • the reactive diluent is compatible with (soluble in) the base film forming polymer; (ii) the reactive diluent serves as a transient plasticizer to allow film coalescence; (iii) the reactive diluent need not be totally soluble in the volatile diluent, but rather is initially distributed between the organic liquid phase and the polymer phase and during evaporation of the volatile diluent is translocated totally to the polymer phase; (iv) because the reactive diluent is essentially non-volatile and becomes a part of the final coating, the total non-volatiles (total solids) of the coating is equal to the sum of the polymer including the cross-linker and the reactive diluent thus allowing lower volatile organic emissions.
  • Figure 2 is a simplified compositional phase diagram of a hypothetical high solids solution coating composition representing A, as the volatile organic solvent, the reactive solvent as C, and the film forming polymer including any required cross-linking agent as B.
  • A the volatile organic solvent
  • C the reactive solvent
  • B the film forming polymer including any required cross-linking agent
  • the point E represents the applications composition of the high solids solution coating.
  • the straight line E-D represents the changing compositions during the film forming process.
  • the dashed line E-B represents the film forming pathway of a corresponding solution coating when C is a volatile organic solvent.
  • the notable features of Figure 2 are: (i) The reactive solvent is generally miscible with the volatile organic solvent; the line A-C is in the one phase region in its entirety. (ii) The coatings polymer is soluble in the reactive solvent; the line C-B is in the one phase region in its entirety. (iii) The reactive solvent is essentially non-volatile and becomes a part of the final coating and consequently, the total solids (non-volatiles) in the film, point D, is equal to the sum of the polymer including any required cross-linker and the reactive solvent.
  • reaction product of polymer, reactive diluent and/or reactive solvent and the cross-linking agent must have suitable properties such as toughness, adhesion, impact resistance, abrasion resistance, scratch resistance, resistance to solvents, chemicals, acids, and bases. It must have good color, gloss, and stability as is required according to the end use application. All of the above is well understood by those skilled in the art.
  • the coatings technologist adapted materials which were readily available for use as reactive solvents and reactive diluents. Many of these materials have limited utility because of excessive volatility, limited reactivity, poor compatibility with the base film forming system, and in general degradation of overall coatings performance.
  • Typical of the early reactive solvents and diluents are higher boiling polyols e.g., glycerol, monoglycerides of unsaturated fatty acids, 1,2,6-hexanetriol and its mono ester derivatives, ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, hexylene glycol, 1,4-butanediol, and the like.
  • polyether diols derived from bisphenol A and ethylene or propylene oxide. Still later, hydroxy terminated polyesters were introduced. These materials are low molecular weight polyesters of M.W. 300 to 3000 derived from caprolactone, cyclic diols, e.g., cyclohexane dimethanol and dibasic acids such as phthalic, isophthalic, maleic, succinic and the like. Often small quantities of triols or tetrols were used to create polyfunctionality in the polyester. These materials are in effect very low molecular weight oil less alkyds. They are characterized by a broad compatibility, good co-reactivity, and low volatility. These materials represent an improvement over the polyether diols, however they provide neither the viscosity reduction for many applications methods including spray and electrostatic spray nor performance required for the more demanding end uses.
  • the substituted carbamates of the present invention have as an integral part of their structure a plurality of reactive -OH and/or -NHCO- groups which are capable, through the application of heat and/or in the presence of catalytic agents when required, of reacting with the base film forming polymers and cross-linking agents.
  • High solids coating compositions meeting the objects above can be prepared by blending;
  • R' - -O-R'' wherein each of R' and R'' is a monovalent radical selected from the group consisting of hydrogen, alkyl groups having 1 to about 10 carbons, hydroxyalkyl groups having 2 to about 4 carbon atoms, hydroxyalkyleneoxy groups and hydroxypolyalkyleneoxy groups and R''' is the same as R' or R'' except that it cannot be hydrogen, with the provisos that: said hydroxyalkyl, hydroxyalkyleneoxy and hydroxypolyalkyleneoxy groups contain at least 1 OH group; said R' and R'' or R' and R''' groups can unite to form a carbon ring structure; and said carbamate derivatives contain either at least one -NH and one -OH group or at least two OH groups;
  • the monovalent radicals may be substituted with ether, halogen, quaternary ammonium, sulfonium, phosphonium and like substituents.
  • Suitable organic polymers for use in the present invention include polymers which contain a plurality of reactive -OH and/or -NHCOO -groups.
  • Preferred crosslinkable organic polymers for use in this invention having as an integral part of their structure a plurality of reactive -OH and/or -NH groups include:
  • Hydroxyl containing vinyl interpolymers such as styrene/acrylic copolymers.
  • the ratio of the amounts of solvent and reactive diluent or cosolvent used to prepare the coating compositions is dictated by the type of coating desired.
  • the amount of reactive diluent is usually determined by the film properties desired. Usually these can be attained by ratios of reactive diluent/solvent in the range of about 5/95 to about 30/70.
  • the ratio of reactive cosolvent to solvent is limited by the solubility characteristics of the polymer. Thus a more soluble polymer would require less reactive cosolvent while a less soluble polymer would require more.
  • polymers of these types are soluble in a blend of reactive cosolvent/solvent of about 20/80 to about 60/40.
  • the base coating may be formulated at rather high ratios of reactive cosolvent/solvent i.e., about 60/40 to about 90/10 and then let down with solvent to attain application viscosities.
  • One skilled in the art can easily establish the optimum ratios for a particular coating composition with a minimum of experimentation.
  • the amount of organic polymer used in these compositions is not narrowly critical. However, a practical range for the solution type is about 15 to about 45% by weight of polymer with the amount of reactive solvent being about 10 to about 20% by weight, the amount of crosslinker being about 10 to about 30% by weight and the amount of solvent being about 60 to about 5% by weight.
  • a practical range of organic polymer used for the dispersion type of coating composition is about 35 to about 50% by weight, with the amount of reactive diluent being about 5 to about 20% by weight, the amount of crosslinker being about 5 to about 20% by weight and the amount of solvent beingabout 55 to about 10% by weight.
  • the reactive carbamate derivatives in the coating composition claimed herein can be designated as either reactive cosolvents or reactive diluents depending on the type of coatings formed.
  • the carbamates function as reactive diluents
  • the carbamates function as reactive cosolvents.
  • the term reactive is used herein to mean that the carbamate derivatives can be incorporated into the finished coating by crosslinking agents which cure through NH and/or OH groups.
  • the reactive carbamates used in this invention may be represented by the following: butyl 6-hydroxyhexylcarbamate 2-ethylhexyl 4-hydroxybutylcarbamate butyl 2-hydroxyethylcarbamate 2-ethylhexyl 2,3-dihydroxy-1-propylcarbamate butyl 2,3-dihydroxy-1-propylcarbamate hexyl bis-(2-hydroxyethyl)carbamate 2-(2-hydroxyethoxy) ethyl carbamate 4-hydroxybutyl carbamate 2-hydroxy-1-propyl carbamate 1-hydroxy-2-propyl carbamate 2-hydroxyethyl carbamate 1,3-dihydroxy-2-propyl carbamate 2,3-dihydroxy-1-propyl carbamate 2-hydroxydecyl carbamate 1-(hydroxymethyl)nonyl carbamate 2-hydroxyethyl ( 2-hydroxyethy1)-(ethyl)carbamate
  • Suitable crosslinking agents for the high solids coating compositions described herein are methylol phenols, such as 2,4,6-trimethylolphenol, polyepoxides, such as the glycidyl epoxides or cycloaliphatic epoxides (Araldite* 297, Epon* 582, etc.) and the aminoplasts such as the reaction product of an aldehyde (e.g. formaldehyde, acetaldehyde, paraformaldehyde, trioxane, etc.) with urea, thiourea, melamine, benzoguanamine, acetoguanamine, dicyandiamine and the like.
  • aldehyde e.g. formaldehyde, acetaldehyde, paraformaldehyde, trioxane, etc.
  • the aminoplasts may be etherified with a lower alcohol such as methyl, ethyl, butyl, isobutyl, propyl or isopropyl alcohol.
  • Aminoplasts which are of particular value in high soli.ds coating compositions are the methylated urea-formaldehyde resins, the alkylated benzoguanamines and methylated melamine-formaldehyde resins with the latter being the most desirable.
  • crosslinking agent is not an aminoplast unless there are two or more or no OH groups on the R''' moiety or unless R' and R'' are each hydrogen or neither R' nor R'' is hydrogen.
  • an acidic catalyst is preferred.
  • alkylsulfonic acids such as methane sulfonic acid, ethane sulfonic acid and the like
  • arylsulfonic acids such as p-toluene sulfonic acid
  • alkylaryl sulfonic acids such as a C 10 to C 18 alkylbenzene sulfonic acid
  • dialkyl hydrogen phosphates such as diamyl hydrogen phosphate
  • aryl hydrogen phosphates such as diphenyl hydrogen phosphate and phosphoric acid itself.
  • a blocked isocyanate is an isocyanate adduct which is stable at ambient conditions but dissociates to regenerate isocyanate functionality under the influence of heat. Temperatures of 120 to about 250°C are necessary to release the blocking groups which are usually volatilized from the coating.
  • the dissociation temperature of blocked isocyanates based on commercially utilized blocking agents decrease in the order: epsilon-caprolactam, phenols, methyl ethyl ketoxime, and active methylene compounds.
  • the amount of catalyst required to promote the reaction is dependent upon the curing conditions required in the coating process. Those skilled in the art may readily determine the catalyst level with a minimum of experimentation. In practice if a catalyst is desired it is usually in the level of .02 to about 1% based on the weight of the organic polymer.
