Application
Areas of application
Acronal® Plus 7023 is used to manufacture elastic coatings such as elastic
top and mid coats, renderings and wall putty. Acronal® Plus 7023 is suitable
for premium elastic coatings in all polluted environment.

Processing
It is advisable to disperse the pigments and extenders with wetting and
dispersing agents such as Dispex® CX 4320 and water-soluble
polyphosphates in an alkaline medium in advance before the emulsion
polymer is added. It is only when the products with very high viscosity are
being mixed in low-speed mixers that Acronal® Plus 7023 should be added
together with the wetting and dispersing agents.

Acronal® Plus 7023 has good pigment binding power and very good
compatibility with pigments and extenders.

Various thickeners can be added to emulsion paints in order to adjust their

viscosity and workability. Cellulose ethers, polyacrylates, diurethane
thickeners (such as Rheovis® 1125, Rheovis® PU 1280 and Rheovis® PE
1230) and bentonite can be used. The choice of thickener depends on
whether the coating is expected to be free-flowing or more thixotropic.

Solvents need to be added in order to enable the polymer to form a uniform

film at temperatures below ambient temperature (e.g. white spirit, glycol
ethers and their acetates, or Loxanol® CA 5308). It is usually sufficient to
add these solvents at a level of 1-3 %, expressed as a proportion of the total
formulation. Short-chain alcohols and glycols improve the freeze-thaw
resistance of paints, but they cannot be used to lower the film-forming
temperature. If possible, solvents should not be added direct to the emulsion
polymer, they should be mixed with the pigment paste and then added.

Like all finely divided emulsion polymers, Acronal® Plus 7023 has a
tendency to foam. It is therefore necessary to add a commercial defoamer
(e.g. Foamaster® MO NDW or Foamstar® ST 2410 the level of 0.3-1.0%.
Trials should be carried out to test the effectiveness of the defoamer.

Acronal® PLUS 7023 itself is resistant to microorganisms in the form in

which it is supplied, but preservatives need to be added to products
formulated with Acronal® Plus 7023 to protect them from attack by
microorganisms over long periods in storage. Trials should always be carried
out to test the compatibility and efficacy of the preservatives.

Customers have to carry out their own trials when developing and processing
products based on Acronal® Plus 7023. The compatibility of Acronal® Plus

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.

Labeling
According to all the data at our disposal, Acronal® Plus 7023 does not need
to be labeled 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 during storage
with metals or alloys that are susceptible to corrosion. It is important to
ensure that containers are kept tightly sealed and the headspace of bulk
storage tanks must be kept saturated with water vapor. This product must
not be exposed to high temperatures and it must be protected from frost. The
product should not be exposed to direct sunlight for long periods of time.

Acronal® Plus 7023 has a shelf life of six months at 10-30 ° C, provided due
attention is paid to the hygiene of tanks and storage facilities.

We would recommend treating this product with a biocide in order to prevent

problems with microorganisms from occurring during storage and
processing. Further details are given in our leaflet on “The handling and
storage of polymer dispersions”.
