Solvent-based polyaspartic topcoat

Product introduction

A solvent-based two-component coating composed of polyaspartic resin and aliphatic isocyanate cured.

Characteristic：

■ Quick drying, short opening time

■ Excellent weather resistance

■ Excellent scratch and abrasion resistance

Application：

Mainly used in high wear and scratch resistance requirements, with high hardness and excellent wear resistance, and good weather resistance and color retention performance, this topcoat is suitable for indoor and outdoor parking lots, indoor decorative floor and heavy industrial floor. The temperature is still solidified quickly at 0 °C.  It is containing solvents, When it is used in indoor, must assess environmental hazards.
