Light color csa binder 82.5 tile adhesive GRC 

Light color csa binder 82.5 is a type of CSA binder,which has light color and easy to be colored in different colors.It is a hydraulic binder based on calcium sulphoaluminate. With the same properties to csa binder,it is also widely used in dry mixed mortar,adhesive,urgent repair,grc products ect.

Features:

High early strength, micro expansive, anti-sulphate, fast set, low alkali, rapid hardening, low CO2,waterproof ect.

This CSA BINDER is specially produced for Dry-mixed mortars and artificial Stone by our Polar Bear plant in year 2000.
