VINNAPAS® 4240 N

Chemical Family: Vinyl Acetate Ethylene (VAE) Copolymer

VINNAPAS® 4240 N is a multi-purpose dispersible polymer powder for dry mix mortars, specifically suited for ETICS, wall applications, and tile adhesives. It is based on a very flexible copolymer of vinylacetate and ethylene and belongs to the product class VINNAPAS® N, which means that it has a neutral effect on rheology and provides the basic properties of adhesion and flexibility. VINNAPAS® 4240 N is part of our standard range, offering best-in-class solutions.

Brand: VINNAPAS
Features: Abrasion Resistance, Anti-Blocking, Excellent Adhesion, Improved Flexibility, Improved Workability
Color: White
Markets: Building & Construction
Appearance: White to light beige powder
Properties: VINNAPAS® 4240 N is a copolymer powder of vinyl acetate and ethylene and is dispersible in water.; Because of its relatively high ethylene content this resin is soft and flexible.; Its glass transition temperature (Tg) is below the freezing point of water.; Compounds modified with VINNAPAS® 4240 N exhibit improved adhesion, flexural strength, deformability, abrasion resistance, cohesion 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® 4240 N contains a fine mineral filler as an antiblocking agent. It is produced without the addition of organic solvents, plasticizers and film-forming agents.; VINNAPAS® 4240 N has essentially no effect on rheological properties and is a dispersible polymer powder in the lower Tg range. It is a general-purpose powder for end products with low emissions.; It is suitable for formulating compounds with very good adhesion to inorganic and organic substrates, yet showing good flexibility.

Application Details: For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS® 4240 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 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.
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.
