Aqueous dispersion of styrene-acrylic copolymer for anticorrosive coatings

Application area:

It is recommended for the production of environmentally friendly paints, anticorrosion primers for black metals, primer - enamels for black metals, coating coatings for black and non-ferrous metals. It allows to get waterproof, alkali-resistant, high-strength film with excellent adhesion to metal and good anticorrosive properties.

It has more ecological properties in comparison with organo-diluted anticorrosive binders (does not contain solvents).

Can be used in the production of wood coatings (floors, windows, doors).

Product properties:

- high water and alkali resistance;

- good penetrating ability in porous substrates;

good vapor permeability;

- resistance to mechanical stirring.

Recommendations for use:

When composing formulations, it is necessary to check the compatibility of the components. Dispersion is well combined with most traditional components and additives:

- coalescents: butyl diglycol acetate, texanol, white spirit;

- fillers: chalk, calcite, dolomite;

- Defoamers based on silicones and mineral oils (VUK-037, VUK-034, Foamaster, etc.);

- dispersants and wetting agents based on low molecular weight polyacrylates;

- Thickeners based on cellulose ethers, acrylates, polyurethanes.

The dispersion has antibacterial protection, but it is recommended that the preservative be added to the paint composition (Acticide MV, Acticide FI).

Safety requirements:

4 hazard class

Packaging:

П / э container, shipment in container of the consumer is possible under the coordination.

Transportation and storage:
