The non-tar polyurethane waterproof coating is a two-component material that uses water as the chain extender to avoid the toxicity problem of amine chain extenders. After curing, it forms an elastic and seamless rubber waterproof layer.
1. Product features:
． Construction at room temperature, easy to operate, non-toxic and harmless.
． Natural leveling, good extensibility, and can overcome leakage caused by cracking of the base layer.
． It has excellent weather resistance, oil resistance, seawater resistance and corrosion resistance.
． It can be applied in wet conditions (no open water) and has strong adhesion to shorten the construction period.
2. Purpose: Used for waterproofing in basements, toilets, bathrooms, storage tanks, grain depots, roofs, exterior walls, etc.

4. Construction requirements
/>． The base surface is required to be flat, clean, and free of sand and looseness.
． Pour material B into the material according to the proportion, stir for 10 minutes with electric stirring, usually apply it in two to three times, use a scraper to apply it, the force should be even and steady. Generally, a centimeter-thick cement mortar is used as a protective layer. When making a facade protective layer , you can spread sand on the wall when the last coat of paint is not completely cured to enhance the adhesion.
5. Packaging, transportation and storage:
． This product is stored in a dry, ventilated, and cool place. The shelf life is unopened and has a shelf life of one month from the date of production.
． Transportation is handled as non-dangerous goods.
