Product presentation:

“YUHONG”brand SPU-311 Two Components Polyurethane Waterproof Coating is a reactive waterproof coating formed from two components’ reaction, component A is polyurethane prepolymer, component B is a hardener. When use, we mix component A and B at a certain proportion. After being stirred well, it is coated on the construction base surface, then wait for hours’ reaction and curing. It forms a jointless, flexible and strong rubber waterproof layer.

Advantages

·Excellent physical and mechanical properties: Composed of pure polyurethane, good rubber elasticity and resilience, high tensile strength, 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 1.0MPa;
·Good construction performance: two components mixed by a certain proportion and for use on-site, easy construction; brushing 2-3 times up to 2 mm thickness, 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 basement (basement of building, basement parking lot, open-cut subway and passageway), especially suitable for the base layer of basement engineering which is difficult for drying;
·Apply to bathroom,water pool，balcony, parking area;
·Apply to non-exposed roof waterproof engineering.

Reference Dosage

·For each millimeter thick film, coating dosage weight is about 1.5kg/ ㎡ -1.7kg/ ㎡ .
