Single Component Oil Based /Solvent Based Polyurethane Waterproof Coating

Short Description:

The product is flexible oilbased waterproof PU coating with isocyanate and Polyether polyol as mail raw material plus some additives and fillers by polyaddition reaction. By coating it on the base and through the polyurethane prepolymerization reaction between NCO Terminal group and the moisture in the air, it form into a layer of rubber waterproof film on the base surface, which are toughened, flexible, seamless. Features for Single Component Polyurethane Waterproof Coating 1) Easy operation...

    The product is flexible oilbased waterproof PU coating with isocyanate and Polyether polyol as mail raw material plus some additives and fillers by polyaddition reaction. By coating it on the base and through the polyurethane prepolymerization reaction between NCO Terminal group and the moisture in the air, it form into a layer of rubber waterproof film on the base surface, which are toughened, flexible, seamless.

    Features for Single Component Polyurethane Waterproof Coating

    1) Easy operation, no special requirements about base layer.

    2) High tensile strength and elongation, excellent performance to high and low temperature.

    3) Thickness can be 1-3mm one-time brushing, coating film is dense, no pinhole, no bubble.

    4) Strong cohesive force, no need other chemical auxiliaries.

    5) Color can be customized according to customers’ specific requirements.

    Operation Points

    1) Basement should be firm, smooth, clean, internal corner and external corner should be circular arc, diameter of internal corner more than 50mm, external corner more than 10mm.

    2) Suggested coating dosage, thickness of 1mm be 1.3 – 1.5 kg/m2

    3) Brush the basement evenly several times (generally 3 – 4 times), later brushing should be after solidification of former brushing. Underground building should be added reinforced materials.

    4) Coating film thickness, underground 1.2 – 2.0mm, bath room ≥ 1.5mm, when adding reinforced materials between coating films, bottom coating film ≥ 1.0mm, upper coating film ≥ 0.5mm.

    5) Diluting agents of alcoholic acid, nitro-group and water are prohibited.

    6) Smoking and flames are prohibited.

    7) Little sediment is normal, mix evenly before
