Product description

VINNAPAS® 4023 N is a copolymer powder of vinyl acetate and ethylene. It is dispersible in water and has good saponification resistance.

Properties

Compounds modified with VINNAPAS® 4023 N exhibitim proved 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® 4023 N contains a fine mineral filler as an antiblocking agent. It is free of solvents, plasticizers and film-forming agents.

Special features

VINNAPAS® 4023 N has no effect on rheological properties and is a low-emissions, general-purpose powder in the medium Tg range. It is eminently suitable for formulating compounds of high ultimate strength.

Application

Typical applications for VINNAPAS® 4023 N not only for blending with inorganic binders, such as cement, anhydrite, gypsum plaster and hydrated lime for the manufacture of tile adhesives, structural adhesives, wall troweling compounds, joint mortars, plasters and repair mortars, but also as the exclusive binder for synthetic-resin-bound systems.

Processing

For the production of ready-mixed powders, such as dry mortars, adhesives and troweling compounds, blend VINNAPAS® 4023 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 achine. 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.
