It is a chloride-based hardening accelerator, formulated to increase the early strength of concrete and mortar at low temperatures. 

This mix of polyester and epoxy is a product of hybrid chemistry with excellent mechanical properties. The coating has a high grade of hardness, adhesion and flexibility and is possibly the most corrosion-resistant powder coating that  Berger Paints offers. Though it offers very good resistance against weather degradation, it is recommended only for indoor use.
