Spray Polyurea Waterproof Coating
1. Description
A two-component, solvent-free, high-purity, fast-response spray polyurea system. Unique formula design, the polymer formed after curing Urea elastomers have excellent toughness, weather resistance and water resistance.
2. Application
- Its applicable to waterproof and moisture works of roofing, external walls, basements, balconies kitchens and lavatories .
- It is suitable for special buildings like granaries, civil air defense works, bridge projects.
3. Advantages
- Solvent-free environmental protection products;
- Ultra-speed curing, continuous thick coating without sagging on any curved surface, the thickness can be achieved in one spray, and
- the coating is seamless as a whole;
- Construction efficiency is very high, 1,000 square meters for three persons per day, and the coating can be put into use on the same day;
- The coating film has extremely high strength, impact resistance, tear resistance, corrosion resistance, abrasion resistance, puncture resistance, and aging resistance. Protective layer, can be used exposed. Low environmental requirements on the construction site.
