ACRONAL S 790 acrylic dispersion is a styrene-acrylic dispersion (aqueous dispersion of an acrylic acid ester and styrene copolymer) for the manufacture of building paints (both exterior and interior), plasters and fillers, adhesives, used in the production of non-woven materials and textile coatings.

Application Area of ACRONAL S 790:
A feature of ACRONAL S 790 is its unique properties, thanks to which ACRONAL S 790 is used for the manufacture of building paints from high gloss to matt, which can be applied to plaster, masonry, asbestos cement, concrete, wood and other substrates both inside and outside the building.
In addition, having an extremely high pigment capacity on ACRONAL S 790, ACRONAL S 790 is possible to obtain highly filled systems (paints, plasters, putties, etc.) that do not lose their high consumer properties, while being cheaper in terms of the cost of ACRONAL S 790.
As a binder for nonwovens and textile coverings, ACRONAL S 790 is applied by impregnating, painting or spraying.

Processing of ACRONAL S 790:
Paints are produced in the usual way in high speed dissolvers.
Pigments and fillers are recommended to be first dispersed in the presence of wetting agents and dispersants (eg Pigment Dispersants N or A or water-soluble polyphosphates) before introducing the dispersion in an alkaline medium.
Only in the production of high viscosity, high solids products (eg texture coatings and fillers) which are produced in low speed mixers should ACRONAL S 790 be added along with the auxiliaries.

ACRONAL S 790 is characterized by high pigment absorption and excellent compatibility with fillers.
Exceptions are pigments that are difficult to crosslink, such as carbon black or calcium sulfate and zinc oxide, which can lead to high viscosity.

To control the viscosity and optimize the consumer properties of ACRONAL S 790, ACRONAL S 790 is usually necessary to add thickeners.
The most commonly used thickeners are cellulose ethers, polyacrylate or diurethane thickeners (eg Latecoll D or Collacral PU 75, PU 85, LR 8989, LR 8990) or bentonites and polysaccharides.
The choice of thickener depends on how the finished product should be (thixotropic or less viscous).

When pigments are used for coloring formulations, in particular in the form of pigment pastes (eg Luconyl brand), ACRONAL S 790 must be ensured that the thickener does not cause precipitation or flocculation of the pigments.
Therefore, ACRONAL S 790 is recommended to carry out compatibility tests (for storage) and, if necessary, the introduction of non-ionic surfactants (eg Lutensol AP 6 grades).

A small addition of LumitenNOC 30 improves compatibility with cement and lime, provides storage stability for highly pigmented interior paints in hard water applications, and facilitates cleaning of work tools.

For a successful film formation at temperatures below 20°C, the addition of coalescents such as white spirit, glycol ethers and Lusolvan FBH, SolvenonPP is recommended.
The recommended consumption is about 2% (based on the total volume).

To make the film particularly flexible, plasticizers can be added, e.g. Plastilit 3060 or chlorinated paraffin or phthalic acid ester.
ACRONAL S 790 is also possible to mix ACRONAL S 790 with soft dispersions (eg ACRONAL S 400) which promote the formation of a transparent film.

Mixing with dispersions based on pure acrylate or polyvinyl esters is also possible, but does not give a transparent film and does not offer any technical advantages.
The compatibility of ACRONAL S 790 with other dispersions is improved with the addition of CollacralVAL, a stabilizing protective colloid.

Like all fine dispersions, ACRONAL S 790 tends to foam.
Thus, ACRONAL S 790 is necessary to introduce antifoam agents in the amounts recommended by the manufacturers (approx. 0.3 - 1%).
The effectiveness of defoamers must be determined empirically.

Although ACRONAL S 790 is protected from attack by microorganisms, preservatives must be added to final products to ensure their stability during storage.
The compatibility and effectiveness of the preservative used should always be tested empirically.

Manufacturers should conduct their own rigorous product development trials using ACRONAL S 790 as our trials cannot cover the full range of factors that can influence product manufacturing and use (e.g. component compatibility, mixing process, adhesion to various substrates, and etc.)
Viscosity stability tests should also be carried out after storage at 50°C.

Storage of ACRONAL S 790:
ACRONAL S 790 during storage and processing should not come into contact with corrosive metals or their alloys without protective coatings.
Product containers must be tightly closed during storage and free air space above ACRONAL S 790 must be saturated with moisture.
ACRONAL S 790 must not be exposed to extreme heat or freezing.

To avoid problems with micro-organisms, the hygiene measures for product storage containers must be observed.

The shelf life of ACRONAL S 790 is 6 months when stored at 10 - 30 ºС

Safety of ACRONAL S 790:
The usual requirements for handling chemicals and local industrial hygiene regulations must be followed.
Efficient ventilation must be provided during processing, as well as personal protective equipment for the skin and goggles.
