Product description

VINNAPAS® 5043 N is a copolymer powder of vinyl acetate and ethylene. It is dispersible in water and has very good saponification resistance. Because of its relatively high ethylene content, this resin is soft and flexible. Its glass transition temperature is below freezing point.

Properties

Compounds modified with VINNAPAS® 5043 N exhibit improved adhesion, flexural strength in bending, deformability, abrasion resistance and are easier to process. Leveling, thixotropy and water retention are essentially unaffected. The product is ideal for use in combination with other mortar additives intended to enhance specific properties. VINNAPAS® 5043 N contains a fine mineral filler as an antiblocking agent. It is free of solvents, plasticizers and film-forming agents.

Special Features

VINNAPAS® 5043 N has no effect on rheological properties and is a low-emission, general-purpose powder in the lower Tg range. It is suitable for formulating highly flexible compounds with very good adhesion to organic substrates (polystyrene).

Application

Typical applications for VINNAPAS® 5043 N blending with inorganic binders such as cement, anhydrite, gypsum plaster and hydrated lime for the manufacture of tile and construction adhesives, adhesive and embedding mortars for thermal insulation and finish systems, flooring compounds, wall troweling compounds and repair mortars, but also as the sole binder for synthetic-resin-bound systems.

Processing

For the production of ready-mixed powders, such as dry mortars, adhesives and troweling compounds, blend VINNAPAS® 5043 N with the other dry ingredients in appropriate equipment. Temperatures should not be allowed to rise excessively during mixing because otherwise the dispersible polymer powder could agglomerate and lead to the formation of small lumps of resin. The mortar or troweling compound is prepared for use by adding the recommended amount of water and mixing by hand or machine. Since hand mixing generates little shear force, we recommend allowing the fresh mortar to slake for 5 minutes and then stirring it again. This is usually unnecessary where mechanical mixers are employed.
