  • What is Redispersible polymer powder!

    Redispersible polymer powder is a vinyl acetate and ethylene based co-polymer which is produced by spray drying technology used mainly as polymer binder in various contruction applications like cement based wall putty, cement mortars, cement based tile adhesives. Higher Tg based redispersible powders have lower ethylene polymer content and higher vinyl acetate polymer content which leads to hard film and lower Tg based redispersible powders have higher ethylene polymer content and lower vinyl acetate polymer content which results in flexible films adding more workability to cement based formulations.
  • Concept

    To meet today’s technical requirements; almost all dry mix mortars require polymer modification. Many cementitious mortars contain cellulose ethers as an additive to improve water retention and workability. However after setting and drying they will adhere poorly. In addition cementitious mortars are very hard, brittle and inflexible materials, whereas for many applications flexible and deformable cementitious materials are essential. As a consequence for almost all applications in modern construction, the modification of cementitious mortars with polymers is a must.
  • Description

    REDISPERSIBLE POLYMER POWDER is a free-flowing, white powder obtained by spray drying of an aqueous vinyl acetate-ethylene copolymer dispersion. Redispersible polymer powders are polymer emulsions which have been converted by spray drying (atomizing the aqueous polymer dispersions in a stream of hot air) to free flowing powders. When blended with water, these powders redisperse back into liquid emulsions with essentially identical properties to the original emulsions.
