Polyaspartic High solids Elastic Waterproof coating

Product introduction：

HA8500 is a two-component, high-performance polyaspartic ester intermediate coat, specifically designed for demanding industrial environments and high-performance protective coating systems. Formulated from polyaspartic ester resins, pigments, fillers, additives, solvents, and MDI curing agents, it plays a pivotal intercoat role in multi-layer systems, providing exceptional physical protection and a stable foundation for the entire coating.

Characteristic：

■ Thick film construction,more than 500μm at a time

■ Great adhesion with epoxy primer and polyurea topcoat

■ Excellent elongation and Tensile strengt

■ Simple construction and quick drying

Application： For the waterproofing and anti-corrosion to concrete substrate(basement, bridge, roof, warehouse, water park),foam, plastic and other substrates; for waterproofing and anti-corrosion of buried steel structure outer layer.
