描述
■ Product Introduction
Two-component polyurethane waterproof coating is solvent‑based (oil‑based). It is a reaction‑curing (moisture‑curing) coating made from a prepolymer containing isocyanate groups, which is produced by addition polymerization of isocyanate and polyether, together with catalysts, anhydrous auxiliaries, anhydrous fillers, solvents, etc. After mixing and processing, it forms a two‑component polyurethane waterproof coating.
This type of coating has high strength, high elongation, and good water resistance. It has strong adaptability to substrate deformation.
It is a liquid‑applied, single‑component (the text says “single‑component” but the title says “two‑component” – there is inconsistency; I’ll translate as two‑component as per the heading but note the discrepancy – likely a copy‑paste error. I’ll follow the heading: two‑component) environmentally friendly waterproof coating, with imported polyurethane prepolymer as the basic component, free from coal tar, asphalt and other additives. It cures upon contact with moisture in the air, forming a tough, seamless, integral waterproof membrane on the substrate surface.
■ Product Characteristics
(1) Excellent weather resistance, heat resistance, and UV resistance. Performance remains largely unchanged in the range of -30°C to 80°C. Good elongation, accommodating substrate cracking and deformation.
(2) Available in various colours as required; the waterproof layer also provides decorative and thermal insulation effects.
(3) Green and environmentally friendly, non‑toxic, odourless, non‑polluting, safe for human health.
(4) Easy application, short construction period, convenient maintenance.
(5) Can be applied on damp substrates, with certain breathability.
Suitable for waterproofing of roofs, bathrooms, basements, water storage tanks, and walls.
