Polyaspartic High solids Elastic Waterproof coating
HA8500 is consist of Polyaspartic esters and variety of pigment, filler,additive ,solvent and MDI.
Product introduction：
HA8500 is a two-component, high-performance polyaspartic ester intermediate coating, 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.

The above data are for guidance only. Actual drying time / time interval before coating can be long or short, depending on film thickness, ventilation, humidity, lower paint, preloading requirements and mechanical strength.
Painting matching：
Applicable under coat: epoxy primer, Polyurea Coating, or refer to our recommended package
Applicable top coating: polyaspartic polyurea topcoat
Surface treatment:
1,Rinse with salt water and other water-soluble dirt
2,Remove grease with a suitable detergent and degreaser
3,Make sure the surface is clean and dry before construction
4,Note the distance between the coating and the primer
