One-component polyurethane waterproof coating is a reactive flexible waterproof coating made of isocyanate and polyether as the main raw materials and various additives. This product has good physical properties, strong adhesion, and can be cured at room temperature and humidity. 1. Performance and characteristics
． The product has high strength, high elongation, high solid content and strong adhesion.
． Natural leveling, good extensibility, and can overcome leakage caused by cracking of the base layer.
． Construction at room temperature is easy to operate, non-toxic and harmless, and has excellent weather resistance and aging resistance.
． It is easy to construct and overcomes the shortcomings of two-component polyurethane waterproof coatings that require metering and mixing, ensuring stable product quality and waterproofing effects of the project.

3. Construction requirements
． The base surface is required to be flat, clean, free of sand and looseness.
． During construction, the base surface should be inspected first to ensure that it meets the requirements. A layer of primer should be applied first, and the primer must be even.
． After the primer is cured, apply it a second time. The direction of application must be perpendicular to the previous application to prevent missed scratches. Apply three to five times in sequence.
． After completion, no one is allowed to enter the building before the waterproof layer is solidified, and no descending process is allowed to avoid damaging the waterproof layer.
4. 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.
