Polyurethane Waterproof Coating - High-Speed Railway Passenger Dedicated Line

Abstract high-speed iron-specific polyurethane (high resistance) waterproof coating belongs to group double copy chemical reaction type waterproof coating, methyl group ether polyester condensation cyanate different polymer body front, group b copy seal lower end is through improver, increase Plasticizer and heavier copy and facilitate the composition of the liquid color gel; usually the temperature makes the solidification mixed to form a high-strength use stone armor b The ratio of the two copy groups is mixed evenly, with a waterproof base, extended strong elastic coating Layer film rubber, functional products belong to chemical reaction two-component material waterproof type curing, belong to environmental protection products, product strength can climb up to 6.0Mpa, stretching can climb more than 450%, low temperature rises below 35 ° c, and the cured product is formed Hou joints and filled with elastic waterproof coatings cannot improve the established reverse osmosis waterproofing ability, especially with high strength and expansion, strong adaptability based on cracking or stretching; simple building products, building stones only need to maintain component armor The proportion of base b is evenly mixed, brushing or spraying the known waterproof base can be cold-resistant construction, easy maintenance, water paint, only the damaged local patch can become the original waterproof effect, saving stone, effort, and low cost; the color can be Adjustment, you can find the color, pay attention to the thinner is not diluted with alkyd resin, nitro agent, paint thinner is required, and it is strictly forbidden to contact with water; the construction site should be well ventilated, and fireworks are strictly prohibited; how to find the material b has stone precipitation phenomenon, should be mixed Use again after smoothing.
