Polyurethane waterproof coating is a mixture of isocyanate and polyether polyol as main raw materials, with a variety of additives and fillers after machine processing. The polyurethane coating is a reactive curing polymer coating, and its reaction mechanism is NCO end group in polyurethane prepolymer. After contact with the air or moisture in the base course and solidify into a film to form a seamless, strong adhesive force, integral and elastic layer which is a tough waterproof coating.
Wha is the features of polyurethane waterproof coating?
(1) The polyurethane coating have excellent mechanical properties for waterproofing: the waterproofing film once formed has high tensile strength, good elongation, and good resilience, Once is applied. it can effectively resist the stretching, cracking and deformation of the base course, and has excellent waterproof effect.
(2) The polyurethane coating have good bonding performance and strong adhesion: the waterproofing layer formed with polyurethane coating has good adhesion with concrete, steel structure, wood, rigid polyurethane and other materials in the daily use.
(3) The polyurethane coating have good integrity: polyurethane coating can be adapted to the construction of base course with any complex shape and form, it is a jointless waterproof coating.
(4) Excellent water resistance and corrosion resistance with polyurethane coating: the waterproofing film can be soaked in water for a long time, and it is acid-base corrosion and mildew resistant, especially suitable for long-term waterproof areas or parts.
(5) The good construction performance of polyurethane waterproofing coating: This waterproofing coating can be used for the construction of buildings with complex structures. It can be packaged in one component and opened up, which is convenient and fast applied to the works and in this way to avoid the product quality instability caused by improper proportioning of multi-component materials is avoided.
Where can the polyurethane coating be applied?
The one part polyurethane coating can be applicable to underground works (including building basements, underground garages, open cut subway and passages, and comprehensive pipe gallery), for waterproof and seepage proof works of the floor, toilet and bathroom, pool, balcony, etc; It can also be used for waterproof of roofing to protect the roofs.
