Coating classification: high strength polyurethane waterproof coating spu-361

Core tip: brief introduction: high strength polyurethane waterproof coating spu-361 is a two-component reaction curing synthetic polymer waterproof coating, which is divided into component A and component B Component A is polyurethane prepolymer obtained by polycondensation of polyether and isocyanate, and component B is a liquid composed of solid curing agent, thickener, chain extender and filler When in use, a and B components are mixed in a certain proportion, mixed evenly, scraped and coated on the base surface to be constructed, and after several hours, the reaction is consolidated into a waterproof coating with elasticity, toughness and durability Features: high strength polyurethane waterproof coating SPU- Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Introduction: high strength polyurethane waterproof coating spu-361 is a two-component reaction curing synthetic polymer waterproof coating, which is divided into a component and B component Component A is polyurethane prepolymer obtained by polycondensation of polyether and isocyanate, and component B is a liquid composed of solid curing agent, thickener, chain extender and filler When in use, a and B components are mixed in a certain proportion, mixed evenly, scraped and coated on the base surface to be constructed, and after several hours, the reaction is consolidated into a waterproof coating with elasticity, toughness and durability Features: the features of spu-361 are as follows: ① spu-361 has high strength, good elasticity, strong adhesion and excellent physical properties; ② spu-361 can be thick coated with dense film without bubbles; ③ High strength polyurethane waterproof coating spu-361 does not contain benzene solvent, no coal tar component, no pollution to the environment, and is a kind of environmental protection coating with excellent performance; ④ high strength polyurethane waterproof coating spu-361 is in liquid state, cold construction, safe and convenient construction; ⑤ high strength polyurethane waterproof coating spu-361 is acid and alkali resistant, corrosion-resistant, heat-resistant, cold resistant and water-resistant Technical indicators: see the following table for technical indicators of spu-361: tensile strength / MPa ≥ 6.0 tensile strength retention rate /% heating treatment ≥ 100 alkali treatment ≥ 70 acid treatment ≥ 80 elongation at break /% no treatment ≥ 450 heating treatment ≥ 450 acid treatment ≥ 450 alkali treatment ≥ 450 low temperature bending property /% no treatment ≤ 35 ℃, no crack, heating, alkali treatment, acid treatment, drying time / h, surface drying time ≤ 4, dry time ≤ 24, impermeability (0.4 MPa, 2 h), impermeability, heating, expansion rate /% - 4.0 ~ 1.0, alkali resistance [saturated Ca (OH) 2 solution, 500 H], no crack, peeling, peeling solid content /% ≥ 98, wet base bonding strength / MPa ≥ 0.6, concrete bonding strength / MPa ≥ 2.5 cement concrete and curing polyurethane waterproof coating bonding strength / MPa ≥ 1.0 tear strength / (n / mm) ≥ 35.0 and concrete peeling strength / (n / mm) ≥ 3.5 Construction: Ø construction process ① base treatment base is firm, solid, flat, without sharp corners; do a good job in waterproof detail node treatment ② According to the construction dosage, mix component A and component B in the proportion of 1:1 The mixing apparatus must be dry and clean ③ The mixture shall be evenly scratched with rubber or plastic plates, with the thickness of 1.5-2.5mm, which shall be applied in 3-4 times, and the latter time shall be applied after the previous time is cured into a film ØØØØØØØ ØØØØØØØØØØØØ A Components B shall not be exposed to the air directly for a long time to prevent self polymerization; components a and B that are not used up after opening the barrel shall be covered tightly immediately Scope of application: high strength polyurethane waterproof coating spu-361 is mainly applicable to all kinds of military projects, nuclear power plants, ship terminals and other special engineering waterproof and moisture-proof projects Storage and transportation: ① high strength polyurethane waterproof coating spu-361 shall be stored in clean, dry and sealed iron bucket to prevent direct sunlight, and the storage temperature shall not be higher than 40 ℃ ② High strength polyurethane waterproof coating spu-361 shall be transported according to the requirements of dangerous goods During transportation, it is necessary to prevent rain, exposure, extrusion, collision and inversion, and keep the package intact ③ Under normal storage and transportation conditions, the storage period of spu-361 is 12 months Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
