Product presentation:

“YUHONG”brand SPU-361 High Strength Polyurethane Waterproof Coating is a double component reacted solidifying type synthetic macromolecule waterproof coating. It consists of component A and component B. Component A is the polyurethane prepolymer and component B is the hardener. When used,we mixe component A and B in certain proportion, stir to mix well,blade coating on the base manually, after hours’ reaction and solidification, they form a jointless, flexible and strong rubber waterproof layer.


Advantages

·Excellent physical and mechanical properties: Composed of pure polyurethane, good rubber elasticity and resilience, tensile strength ≥ 6MPa, elongation ≥ 450%, strong resistance to the deformation of base layer (shrinkage and
cracking);
·Good bonding property, strong adhesion: be bonded with different base layers and directly constructed on the qualified base layers; the bonding strength is more than 2.5MPa;
·Good construction performance: two components mixed by a certain proportion and for use on-site, easy construction; dense coating, pinhole-free, no bubbles;
·Excellent water and corrosion resistance: forming film by chemical reactions, water erosion resistance, corrosion resistance, mildew resistance, especially suitable for long-term soaking parts of waterproof engineering constructions;
·Excellent low temperature flexibility: -35 ℃ low temperature bending without cracking, suitable for low temperature waterproof engineering constructions;
·Environmental friendly: high boiling point solvents, no benzene, toluene, xylene and any other toxic solvents, no coal tar.


Application Range

Apply to railyway, highway, bridge, basement, water pool, refrigerator, ground and any other high-demanding waterproof and damp-proof engineering constructions.


Reference Dosage

For each millimeter thick film, coating dosage weight is about 1.4kg/ ㎡ -1.6kg/ ㎡ .
