• Good application performance: After the two components are mixed according a certain ratio, the product can be applied; thick coating can be made, reaching 2mm after 2-3 courses. The coating film is dense and solid, free of pinholes and bubbles

• Excellent water and corrosion resistance: Chemical reaction-based film formation, and resistant to water erosion, corrosion and mildew, especially suitable for the waterproofness of long immersed parts

• Good bonding performance and strong adhesion: Can be bonded with different substrates, and directly applied on any substrate that meets the requirements, with a bonding strength of over 1.0MPa

• Excellent physical and mechanical properties: Composed of pure polyurethane, good rubber elasticity and resilience, high tensile strength, strong resistance to substrate deformation (shrinkage and cracking)

• Environmental performance: Adopt high boiling point solvent, and free of benzene, toluene, xylene and other toxic solvents, no coal tar components

For a 1mm coating film, the coating usage is approximately 1. 6 - 1. 9kg/㎡.

Substrate treatment → additional waterproof layer in details → coating for large-area waterproof layer → end closure and edge sealing → quality inspection and acceptance → application of protective and isolation layers

• Substrate treatment: The waterproof substrate should be even, solid, dry and free of sharp concave convex, honeycomb, pitted surface, peeling and oil stain. For cracks, deformation joints of base course and grooves left at pipe root, sealing materials shall be embedded and additional waterproof treatment shall be done. For smooth and solid base course, there is no need to apply base treatment agent. Internal and external corners and tube roots should be subject to arc treatment.

• Additional waterproof layer in details: An additional layer should be made first for internal and external corners, pipe roots, deformation seams and other base positions, which are to be coated 2-4 times more (with a thickness of not less than 1mm). If it is necessary to lay matrix reinforcement material, it must be soaked. At the deformation joints, a layer of polyester non-woven fabric shall be laid first, added with coating to form the structure of void laying of an additional waterproof layer.
  

• Coating for large-area waterproof layer: Select a plastic scraper to make even coating, and it is better to apply 2 - 3 times. When there is no substrate treatment agent, the first coating should be thin so as to close substrate pores. After coating, it should be fully cured until the finger contact is not sticky, and then the second coating can be made, generally at an interval of 12h (which may be extended at low temperatures). The second coating should be perpendicular to the first coating. If it is necessary to lay matrix reinforcement material, the coating should be applied while the reinforcement material is being laid.
  

• End closure and edge sealing: Make additional coating for sealing.
  Application of protective and isolation layers: After the coated waterproof layer is finally completed and passed quality inspection (conduct closed water test if necessary), the protective and isolation layers can be laid in accordance with relevant specifications or design requirements.
  

• Store it in a clean, dry and sealed iron bucket.

• During transportation and storage, avoid exposure to sunlight and rain, keep away from fire, prevent collision, and pay attention to ventilation.The best storage temperature is 5-25 ℃, and the maximum temperature should not exceed 40 ℃.

• Under normal transportation and storage conditions, the product lasts for 12 months.

  
  

• The application temperature is 5-35 ℃, and no application shall be allowed in a rainy or snow environment.

• Application should be carried out under the condition of good ventilation, and application personnel should take corresponding safety protection measures.

• Use the product directly without adding any diluent. If dilution is needed, please consult the relevant technical personnel, and conduct small-scale field test. The diluted product can only be applied on a large scale after it is verified that adding diluent does not affect the drying speed of the product.
