PV400 is consist of Polyaspartic esters and HDI, variety of pigment, filler,additive and solvent. All main ingredients are manufactured by own.PV 400 is a high-performance, quick-drying coating system for all types of industrial flooring based on Polyaspartic technology.
Characteristic
■ High solid content, non-toxic environmental protection
■ Excellent resistant to a variety of chemicals such. Acids and alkalis ,Chlorine, salt water, weather resistant.
■ Great adhesion with matched primer and polyaspartic topcoat
■ Excellent elongation at break, impact resistance
■ Excellent waterproofing and decorative function
■ No yellowing, good wear resistance
Application
It is mainly designed and applied to the occasions with high requirements on wear resistance, impact cracking resistance and yellowing resistance.
