VINNAPAS® 4220 L

1 of 218 products in this brand
VINNAPAS® 4220 L is a dispersible polymer powder for dry mix mortars, specifically suited for self-leveling flooring compounds and screeds. It is based on a copolymer of vinylacetate and ethylene in the medium Tg range and belongs to the product class VINNAPAS® L, which means that it improves the leveling and surface properties as well as the stabilization of the fresh mortar. Cured mortars with VINNAPAS® 4220 L have improved adhesion, flexural strength, deformability, and abrasion resistance.

Processing

For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS 4220 L 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® 4220 L is a copolymer powder based on vinyl acetate and ethylene and is dispersible in water.
  • VINNAPAS® 4220 L is a polymeric binder. Blended with inorganic binders, the powder will provide very good workability flexibility, deformability and abrasion resistance.
  • Particularly advantageous is the combination of VINNAPAS® 4220 L and polycaboxylate ethers (PCE) and other synthetic super plasticizers or casein to produce self-leveling flooring compounds and screeds.
  • VINNAPAS® 4220 L achieves smooth surfaces that are free of surface voids.
  • VINNAPAS® 4220 L contains a fine mineral filler as an antiblocking agent. It is produced without the use of organic solvents, plasticizers and film-forming agents. The product thus can be used to produce self-leveling flooring compounds conforming to strict eco-labeling requirements.
  • VINNAPAS® 4220 L is a leveling dispersible polymer powder in the medium Tg range and it is suitable for applications with low emissions.

Storage Information

During storage, protect the product from contact with moisture. Prolonged storage at temperatures above 30 °C, especially in combination with pressure, humidity or exposure to sunlight, may result in blocking. Carefully seal any open containers and store them under suitable conditions. We recommend storing the product in a warehouse that provides cool and dry conditions. Do not store the product for more than six months, starting from the date at which it was received.
