The difference between one-component polyurethane sealant and polyurethane water-swelling waterproof sealant:
1. Distinguish one-component polyurethane sealant and polyurethane water-swelling waterproof sealant in principle: the main component of one-component polyurethane sealant is polyurethane resin, which dries and solidifies in the air and is mainly used for sealing and bonding. The main components of water-swelling waterproof sealant are polymer materials and water-absorbing materials, which can swell in water to block water flow.
2. Distinguish one-component polyurethane sealant and polyurethane water-swellable waterstop sealant based on the construction environment: water-swellable waterstop sealant is suitable for underwater construction, while one-component polyurethane sealant is suitable for sealing and bonding in various indoor and outdoor environments.
3. Distinguish one-component polyurethane sealant from polyurethane water-swelling water-stop sealant in terms of characteristics: Water-swelling water-stop sealant can swell in water to block water flow and has good water resistance and durability, but its adhesion in dry environment is poor. One-component polyurethane sealant has good adhesion and durability, but it does not have the characteristic of swelling when exposed to water.
