Product Information
Acronal® PLUS 7023

Polymer Dispersion for High Quality Elastomeric Architectural Coatings
Acronal® PLUS 7023 is an APEO free anionic polymer dispersion with a medium viscosity, consisting of
small, finely divided particles. Films made from Acronal PLUS 7023 show good DPUR and have an excellent
balance of high strength and flexibility.

Applications
Areas of application
The main field of application for Acronal PLUS 7023 is as a binder for elastomeric wall coating
Processing
Products formulated with Acronal PLUS 7023 can be made up in the usual manner with a high speed
mixer. Dispex® CX 4320 is recommended for dispersing titanium dioxide pigments in propylene glycol or
propylene glycol/water. Dispex® AA polyacrylate types can be used as a co-dispersant or the sole
dispersant, particularly if high levels of calcium carbonate are used.
Associative thickeners, e. g. Rheovis PE 1332, PU 1280 and PU 1191, are particularly suitable for
adjusting the viscosity and flow, because they do not give rise to a yield point in the rheological
characteristic. Acronal® PLUS 7023 displays very high response to associative thickeners. These
thickeners may be combined with hydroxyethyl cellulose or modified cellulose thickeners in order to
reduce any tendency of sagging and to prevent pigment flocculation, although cellulose based thickeners
may reduce the stain and wash resistance of the paint.
Like all dispersions Acronal PLUS 7023 tends to foam, with the consequence that it generally necessitates
the addition of a defoamer like FoamStar® ST2410 in proportions of 0.2 - 1%.
A coalescent is required to ensure satisfactory film formation. Water miscible glycol ethers are particularly
suitable for this purpose. Examples of other suitable coalescent are Texanol® (Eastman Chemical
Company), Solvenon® DpNB (BASF) and Loxanol® CA 5308 (BASF) . Generally 4% wet on wet
dispersion is required to ensure the film coalesces at 5 °C. As with all polymer dispersions care should be
taken when adding solvents so as to not cause coagulation. If a low odor or low VOC paint is to be
formulated then care should also be taken in the selection of the coalescent solvent.
Propylene glycol is suitable for increasing the wet edge time but temporarily impairs the resistance to
blocking and increases the sensitivity to water.
Preservatives should be added to products made up from Acronal PLUS 7023 ap, in order to ensure
adequate protection against microbial attack during long storage periods. Their compatibility and
effectiveness however should be tested also.

Safety
General
The usual precautions for handling chemicals must be observed. These include the measures set out in
the guidelines of the organizations responsible for safety at work, in particular, good ventilation and fume
extraction at the workplace, care of the skin and the wearing of eye protection.
Safety Data Sheet

When using this product, the information and advice given in our Safety Data Sheet should be observed.
Due attention should also be given to the precautions necessary for handling chemicals.
Labelling
According to all the data at our disposal, Acronal PLUS 7023 does not need to be labelled as a
dangerous substance or preparation as defined in the relevant local directives according to their current
status.
Storage
Acronal PLUS 7023 must not be allowed to come into contact with metals or alloys that are susceptible to
corrosion. It is very important to ensure that containers are kept tightly closed or that the airspace in
storage tanks is kept saturated with water vapor. Exposure to frost or sources of intense heat must be
avoided.
Acronal PLUS 7023 contains sufficient preservative for transportation. More preservative must be added
during subsequent storage to protect the material against microbial attack and tank hygiene measures
must be adopted (cf. our Technical Information Bulletin “Storage tanks for polymer dispersions”).
Acronal PLUS 7023 has a shelf life of approximately nine months from date of manufacture at
temperatures between 10°C to 30°C.
