waterproof Coating

waterproof SPUA-351 spray polyurea elastomer coating CE Certificated China well known trade mark "Yuhong" Brand (1)It is fast-set, spray-moulding bi-component elastomer coating consisting of A component and the R component. (2) A component is isocyanic acid semi- prepolymer by reaction between isocyanic acid and low-polymer diol or triol. (3) R component is a mixture of polyether amine, amine extenders, paint, filler and other additives. A component and R component are sprayed through special spraying equipment from other countries. (4) These two components, transmitted to the spray gun from the metering pump, are sprayed to the substrate surface, and become flexible, tenacious waterproofing, corrosion and wear-resisting coating through rapid mixing and rapid reaction consolidation.·Features (1) Rapid consolidation, spray moulding on any curved surface, inclined surface or vertical surface, without sagging (2) Insensitive to humidity and temperature, with no effect on construction (3) 100% solid content, without any VOC, pollution-free and environmentally-friendly (4) Outstanding physical performance, e.g.: tensile strength, elongation, flexibility, as well as wear, aging and corrosion resistance (5) Good thermal stability, can subjected to 120in long run and 350 short-time thermal shock. (6) Like the ordinary coatings, it can be in different colors when adding various kinds of dyes (7) Consecutive, seamless, non-aperture, beautiful and practical (8) Complete equipment, convenient and efficient construction, can meet design thickness through one-time construction Application Scope: Extensively applied in underground waterproofing work, chemical engineering, and anti-corrosion and abrasion-resistance lining, shockproof and skidproof terrace.
