They all have strong adhesion, the chemical properties of the product are stable, they can withstand long-term sunlight exposure, they have high strength, large elongation, good elasticity and good waterproof effect.
It can be applied on a wet base surface, and can be cured into a non-toxic, odorless, highly elastic waterproof film after coating.
It is a new generation of environmentally friendly waterproof material.
Advantages of water-based polyurethane coatings
①Excellent wear resistance.
②Excellent chemical and oil resistance.
③Strong adhesion.
④ Low temperature curing performance.
⑤High decorative performance.
⑥Performance diversity and adjustability.
Through the improvement of the formula, the coating film of polyurethane can be made into a coating film with high hardness, and can also be made into an elastic coating film with excellent flexibility, which greatly enhances the application range of polyurethane coatings.
⑦High temperature and low temperature resistance.
⑧The coating film is non-toxic after curing.
⑨Environmentally friendly low VOC coating.
Disadvantages of water-based polyurethane coatings
① The crosslinking density is low, and the overall performance of waterborne polyurethane coatings still has a certain gap compared with solvent-based polyurethane (PU).
②Poor anti-corrosion performance.
③Slightly less hydrolyzable.
Usage :
1. Overall waterproofing of building roof planes, slopes, internal and external walls, kitchen and bath rooms, swimming pools, gutters etc.
2. Basement: concrete floor, floor beams, shear walls, retaining walls, etc.
3. Waterproofing of tunnels, subway projects, ditches, elevator shafts, sluices, and sewage treatment tanks.
4. Strengthen the sealing of wall pipes, downpipes, expansion joints, and grating joints.
5. Anti-corrosion on the surface of metal water pipes, waterproof and anti-corrosion on galvanized sheet roofs.
