Application :

Kamicryl - 400 is an aqueous polymer dispersion based on Styrene / Acrylates. It is compatible with cement and suitable for cement modification / cementitious compositions. Mortars modified with Kamicryl -400 have good flexibility and durability as well as compressive and impact strength. Kamicryl - 400 can also be used as crack filling and tile jointing compound by mixing with white cement. Other applications for Kamicryl-400 that merit mention are bridging systems and flexible coatings on flat roofs.

Storage:

If it is kept in tightly closed containers, Kamicryl-400 has a shelf life of up to six months at 10 - 300C.
