Universal Sprayed Polyurea

JSD701
Customized processing according to the performance indicators provided by customers, the price of customized products is negotiable.
JSD701 is a 100% solid aromatic polyurea elastomer, which is generated by the reaction of isocyanate components and amino compound components. It requires professional polyurea equipment for spraying and construction. Due to its excellent waterproof, anti-corrosion and good wear resistance, this product is widely used in industrial and commercial anti-corrosion and waterproof fields.
Product features: ① No solvent, 100% solid content, safe, environmentally friendly, no odor ② Fast curing, can be sprayed on any curved surface, inclined surface and vertical surface without sagging. ③ The coating is dense and seamless, with good flexibility
Polyurea: ① Strong adhesion, can be quickly bonded to steel, concrete, wood, fiberglass and other substrates. ② Excellent impact resistance and wear resistance ③ Excellent corrosion resistance and chemical resistance, such as acid, alkali, salt, etc.
Waterproof and anti-corrosion: ① Excellent waterproof performance ② Good shock absorption performance ③ Excellent temperature stability ④ Fast curing, so that the construction area can be quickly restored to use ⑤ Excellent durability, reducing lifetime maintenance costs ⑥ Extend the service life of the spray structure
Scope of product application
Construction, chemical industry, transportation, metallurgy, electricity, aerospace, ocean, shipbuilding
Construction base treatment
Metal surface: It is recommended to sandblast and remove rust to Sa2.5 level of ISO8501-1 or GB8923 standard.
Concrete surface: It should be solid, dense, flat, clean and dry. There should be no sanding, peeling, cracks, honeycomb surface and other phenomena. It is usually necessary to repair with putty.
Wood surface: Clean, dry without burrs, fragments and loose fragments.

Packaging: Component A 210 kg/barrel
Component B 200 kg/barrel
Warranty period is 10 months (from the date of production if the original packaging is not opened)
Storage temperature: 5-35'C
Make sure the product is well sealed and stored in a cool, ventilated environment away from direct sunlight
Notes
1. Before using the product, component B should be fully stirred so that the pigment is evenly mixed. Otherwise, the quality of the product will be affected.
2. If the construction substrate is coated with a primer, please spray polyurea within the appropriate time frame.
3. For the specific use method and overcoating interval of the company's polyurea special primer, please refer to JSD's other product manuals.
4. The company requires customers to test spray an area at the spraying site before formal spraying to ensure that the product mixing ratio, color and spraying effect are correct and ideal. For the specific use of JSD701, please refer to our company's "JSD Spray Polyurea Series Product Construction Instructions"
