Definitions
- the present invention relates to a process for the production of compounds containing allophanate and / or thioallophanate groups, compositions containing uretdione groups and the use of these compositions for the production of polyurethane plastics or coatings.
- the invention also relates to coating compositions containing the compositions and substrates coated with the coating composition.
- Polyaddition products containing uretdione groups are known as crosslinking components for thermally crosslinkable polyurethane (PUR) lacquer and adhesive compositions.
- the crosslinking principle used in these products is the thermal ring opening of the uretdione groups to form isocyanate groups and their reaction with a hydroxy-functional or amino-functional binder.
- crosslinkers containing uretdione groups are used today almost exclusively for the production of split-free polyurethane (PUR) powder coatings (e.g. DE-A 2 312 391, DE-A 2 420 475, EP-A 0 045 994, EP-A 0 045 996, EP-A 0 045 998, EP-A 0 639 598 or EP-A 0 669 353).
- PUR polyurethane
- DBN 1, 5-d
- Lewis acid catalysts such as the tin or zinc compounds mentioned above, are inhibited by acid groups such as carboxyl groups. They can therefore only develop their full catalytic activity in a uretdione system if the hydroxy-functional binder used is free from carboxyl groups. This can be achieved, for example, by simultaneously adding a sufficient amount of an agent which is reactive towards carboxyl groups, for example a carbodiimide or an epoxide.
- quaternary ammonium hydroxides and ammonium fluorides e.g. EP-A 1 334 987
- ammonium carboxylates e.g. EP-A 1 475 399, EP-A 1 522
- phosphonium hydroxides, alcoholates or carboxylates e.g. WO 2005/085315
- metal hydroxides and alcoholates e.g. EP-A 1 475 400
- a uretdione structure can react in two ways during curing, the complete splitting into two isocyanate groups, which subsequently form urethane groups with two hydroxyl groups of the polyol, or a ring opening only on one side with only one hydroxyl group of the polyol to form an allophanate structure.
- both reactions take place side by side in catalyzed uretdione systems, the preference between the two reaction products shifting with the curing conditions, in particular the temperature.
- the trimerization of isocyanate groups to give isocyanurate structures can often be observed to varying degrees.
- the object of the present invention was therefore to provide new catalysts for lowering the hardening temperature of uretdione systems, which lead to the most complete conversion of the uretdione structures and thereby provide a fixed ratio of the reaction products regardless of the hardening temperature.
- compositions containing catalyzed uretdione groups described in more detail below were provided.
- the present invention is based on the surprising observation that special salts with an imidazolium or dihydroimidazolium structure are highly effective catalysts for the reaction of uretdiones with alcohols and / or thiols, with only allophanate, thioallophanate and optionally isocyanurate structures in a fixed ratio.
- WO 201 1/061314 also describes imidazolium salts as a possible alternative to toxicologically questionable tin catalysts, such as. B. dibutyltin dilaurate (DBTL), for the reaction of isocyanates with polyols in polyurethane synthesis.
- B. dibutyltin dilaurate (DBTL) for the reaction of isocyanates with polyols in polyurethane synthesis.
- DBTL dibutyltin dilaurate
- this publication includes a blanket list of possible starting polyisocyanates for urethanization including those with a uretdione structure, there is no mention of the particular suitability of imidazolium and dihydroimidazolium compounds as catalysts for selective uretdione cleavage with the formation of allophanate or Thioallophanate structures.
