PL61-22 Heat-Reflective Thermal Insulation Coating

Overview
Multi-layer coating system for heat reflection and thermal insulation with anti-corrosion and weathering resistance.​

Composition
Synthetic polymer resin, thermal insulation materials, glass microspheres, glass fiber, pigments, fillers, additives, curing agent.​

Typical uses
Cooling and anti-corrosion protection for metal storage tanks, LPG tanks, oil tank trucks, tank equipment exteriors, oil tanks, chemical raw material tanks, and refrigerated trucks.​
Thermal insulation/cooling for exterior surfaces of buildings (e.g., residences, plants, cold storage, modern farms, kiosks) and for wood components.​
