SW-PU 300 is a two-type liquid type (original liquid 10: accelerator 1) semi-rigid urethane resin, which forms the same as SW-PU 200 by injecting the leakage part of concrete and reacting with inflow water.
It is a product that is used by mixing separate accelerators to control the response time of the site according to the condition characteristics (ex:humidity, temperature, gushout water quantity).Use
- Leakage of ceiling joints, walls, and joints of all concrete in the building.
- Filling cavity of concrete.
- Liquid : 20kg (Steel Pail)
- Accelerator : 2kg (Can)
