AXILAT UP 600 B is used to improve workability of fresh mortar, hydrophobic properties. AXILAT UP 600 B is a vinyl acetate, vinyl versatate and maleic ester copolymer resin in redispersible powder form. It is redispersible in water and used in dry mortars to improve workability of fresh mortar, hydrophobic properties, adhesion to conventional substrates, especially after severe ageing conditions, and mechanical properties (flexibility, abrasion resistance and cohesive strength). It is a plasticiser-free powder, particularly suitable for ecologically demanding systems.
