Aqueous emulsion of styrene-acrylic copolymer.
Application:
Recommended for the production of waterborne paints for construction purposes from glossy to matte, for outdoor and indoor use that can be applied on brickwork, plaster, asbestos cement, concrete, wood. Due to the high pigmentally effectively used in highly filled systems: plasters, shpatlevka highly-filled paints.
Can be used in the production of nonwovens, textile coatings, adhesives.
Product properties:
— high compatibility with pigments;
— high resistance to abrasion;
— high alkali resistance;
— high resistance to flaking, excellent adhesion;
— low sensitivity to water;
— resistance to mechanical stirring.

Recommendations for use:
In the preparation of formulations need to check the compatibility of the components. The variance combines well with most traditional components and additives:
— coalescence: butyldiglycol, Texanol, white spirit;
fillers: chalk, calcite, dolomite;
— defoamer based on silicones and mineral oils (PAC-037, WOOK-034, Foamaster, etc.);
the dispersants and wetting agents based on low molecular weight polyacrylates;
— thickeners based on cellulose ethers, acrylates, polyurethanes.
The dispersion has an antibacterial protection, but the paint is recommended to introduce additional container preservative (Acticide MV, Acticide FI).
Due to the low water absorption of the polymer films may reduce flow dispersion in the formulation of aqueous coatings:
Consumption of Akratam AS 05.1
for interior coatings 8-10 %
for exterior coatings up to 15%
Safety requirement:
Hazard class 4
