SZ One-Component Polyurethane Waterproof Coating

Polyurethane (PU) waterproof coating, also known as polyurethane waterproof film material, is a high-grade reactive 

waterproof material polymerized from isocyanates, polyhydroxyl (-OH) or amino (-NH2) curing agent and other 

various additives. According to the curing method, it can be divided into one-component SZ-I water-curing type, 

one-component SZ-II moisture-curing type, and one-component SZ-III air oxidation-curing type. This type of material

can be made into black film or colored film.

Suitable for anti-seepage, moisture-proof and waterproof projects such as roofs, basements, floors, walls, kitchens, 

bathrooms, bathtubs, tunnels, bridge decks of industrial and civil buildings; can be used as additional waterproof 

layers for various projects; can be used as sealing adhesive for polymer series coils. Especially suitable for waterproof 

and anti-seepage of various underground projects and kitchen, bathroom and shower rooms.

Base treatment agent: approx. 0.3kg/㎡; Waterproof layer: 1.8～2kg/㎡ of coating for 1.5mm thickness, 2.5kg/㎡ 

for 2.0mm thickness.

During transportation and storage of PU coating, the packaging barrel must be placed upright and not inverted, 

and should be kept away from high temperature and open flame. Store in a cool and dry room with temperature 

not exceeding 40℃. The storage period is not less than 6 months.
