Processing
For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS® 4040 E 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 by virtue of its thermoplastic properties. The mortar is prepared for use by adding the recommended amount of water and mixing mechanically or by hand. 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.

- Properties
- VINNAPAS® 4040 E is a copolymer powder of vinyl acetate and ethylene that is dispersible in water.
- The high ethylene content makes the resin soft and elastic. Its glass transition temperature is below the freezing point of water.
- VINNAPAS® 4040 E is stabilized with polyvinyl alcohol and a cationic high-molecular-weight polymer.
- Compounds modified with VINNAPAS® 4040 E exhibit improved adhesion, flexural strength, deformability, abrasion resistance and better workability.
- VINNAPAS® 4040 E is ideal for highly polymer-modified cementitious dry-mix mortar formulations. Tremendous ease of processing, excellent adhesion and high flexibility are obtained (e.g. high capacity to bridge sealing-slurry cracks, and high deformability in tile adhesives).
- VINNAPAS® 4040 E contains a fine mineral filler as an anticaking agent. It is produced without the use of organic solvents, plasticizers and film-forming agents.
- VINNAPAS® 4040 E is a dispersible polymer powder with a Tg in the lower range and no effect on rheological properties. It is eminently suitable for formulating highly flexible, low emission compounds with very good adhesion to mineral and organic substrates.
