Single Component Polyurea Waterproof Coating

1.Description

ST800A is a single-component, aromatic, thick-film polyurea anti-corrosion and waterproof coating material. Upon curing, it forms a thick protective film that exhibits excellent adhesion to concrete and steel structures. It is easy to apply and does not require specialized polyurea spraying equipment. Owing to its unique chemical structure, the material demonstrates outstanding chemical resistance, waterproofing performance, and high strength. These properties make it ideally suited for a wide range of applications, including waterproofing of building walls, sealing structural cracks and expansion joints, as well as anti-seepage and leak-stopping operations in harbor docks and dams.

2.Features
