Single-component waterproofing coating
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 surstrate, 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.
Product characteristics
  1. 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.
  2. 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
Applicable scope
Widely used in roofs, basement, toilet, swimming pool, and all kinds of industry and civil building waterproofing

Application technology
  1. Substrate need be firm, smooth, no sundries, inside corner and outside corner should be made into circular arc, the diameter of insider corner should be more than 50mm, and the outside corder should be more than 10mm.
    Ingredient and dosage: according to application dosage, evenly mixing round o use.
    Reference dosage: coating film dosage is about 1.3-1.5kg/sqm when the thickness is 1mm.
  1. Large waterproof application, coating uniformity mixed coating with a rubber or plastic scraper, the thickness is onsistent, generally it is 1.5mm to 2.0mm, should be brushed in 3 to 4 times, the last time brushing should be done after the previous brushing cures and becomes film, and brushing at a ertical direction. Generally as a separate film-forming, for underground project board, should pave a layer of felt reinforced material in addition.Coating thickness: to underground project thickness is 1.2 to 2.0mm, generally 1.5mm; to toilet thickness is not less than 1.5mm; to multilayer waterproof of exposured roof construction thickness is not less than 1.2mm ; to one layer waterproof of grade IIIwaterproof, thickness is not less than 2mm;Fishing layer application.scatter the cleaned sand before the last time brushing is not solidified.
Protection layer: on the coating film surface should do insulation protection as the design.
Attention
  1. Diluent can't be alcohol acid,nitro diluent such as paint thinner,don't touch with water
  2. Keep ventilateration, no fire.
  3. If the material has slight desposition,it should be evenly mixed before use.
  4. The construction site must keep good ventilation and should not apply in rainy day.
  5. Open the cover when use, it must be used up in 40minutes.
  6. If find broken coating film in construction site, dig around the broken opening with cutting kinfe, and then brush waterproofing coating and repair.
Storage and attention items
  1. Keep material in the room which is dry and ventilateration
  2. Avoid direct sunlight when transportation, avoid collisions and attention to fire
  3. The guarantee period of storage is six months,the coating out of storage time should be used after checking.
