Однокомпонентный полиуретановый водонепроницаемое покрытие

<Description> 1)Single component waterproofing coating is a polymer waterproof coating of reactive type of moisture-curable film , It is made of Isocyanate and polyether as main material, mixing with solid agents, plasticizers and other additives using special technology by high temperatures dehydration and polymerization.Coating it in the substrate , through the reaction between NCO end group in polyurethane prepolymer and moisture in air, which forms tough ,soft and jointless rubber waterproofing film on the substrate. 2)single component waterproofing coating ,Easy to apply , the requirement to Moisture content of the base is not high, it can be applied on the more moist surface, also available on the surface it’s relative humidity is more big. Polyurethane coating film has high strength and elongation,good elasticity ,good high temperature and low temperature resistance, and high adaptability to substrate shrinkage and cracks 3)Can coat 1mm to 3mm thick one time, coated film is dense ,no bubbles, and high bonding power . 4)Not necessary to brush the substrate treatment agent on the various substrate which is up to the standard <Characteristic> 1. Single-component with convenient construction2. Excellent Physical and Mechanical Property:It has high strenght, elongation at break, rebound elasticity, anti-weary and aging-resistance.3. Good Weather Resistance:It can adapt the climate changes in hot or cold areas.4. Envrionment-friendly:There is no solven, little VOC, no poison and no smell.5. The coating can form a film with the reaction with water so it can be applied on the wet substrate, and then it can be applied on more places.6. High Solid Content (no less than 94%)<Usace> Applicable for roof, wall, kitchen and toilet, basement, cisterns underground, tunnel, bridge, etc. Can be used on wet or dry brick, mortar, concrete, metal surface and various insulation layer, waterproof layer directly, can be used for pipe antisepsis. <Specification> Technical data Confirming toGB/T 19250-2003 NOITEMINDEXIII1Sold content /%≥80%2Dry time of outside /h≤12hDry time of inside /h≤24h3Tensile strength Mpa≥1.92.454Fractrre elongation %≥4504505Water impermeability 0.3Mpa,30minImpermeability6Bending at low lemperature °C≤-407Bonding strength of moistbase Mpa≥0.5
