Product Overview Froouct Introduction:
Two-component polyurethane waterproof coatings are two-component reactive curing waterproof coatings. Component A is a prepolymer made of polymerization reaction of polyether and isocyanate as the main materials, and component B is refined from fillers, vulcanizing agents, catalysts, resins and additives. The components A and B are stirred evenly according to a certain mix ratio, applied and scraped on the base surface, and formed an overall and elastic waterproof adhesive film after melting.

Product Speciication:
1
Scope of Application:
1. Waterproofing the interior and exterior of all kinds of underground buildings, including underground passages, tunnels, garages, pools, etc.
2. Concrete roofs, gutters, canopies, flower beds, etc. in all kinds of non-humid states.
Construction method:
The base surface must be clean, dry, flat, solid, free of dust and oil. The bottom layer treatment of the construction surface can be diluted with 3-10% solvent and then rolled or painted. During construction, mix groups A and B according to a certain mix ratio and stir evenly, use rubber scrapers or plastic scrapers to coat the materials ready, and the amount of ingredients should be controlled within 30 minutes at room temperature. Detailed structures such as yin and yang corners and pipe openings can be reinforced with non-woven fabrics. During low-temperature construction, if curing needs to be accelerated, an appropriate amount of catalyst can be added.
