Polyaspartic High solids Elastic Waterproof coating

Product introduction：HA8500 is consist of Polyaspartic esters and variety of pigment, filler,additive ,solvent and MDI. All main ingredients are manufactured by own.

Characteristic：

■ Thick film construction, filming 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.

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
