ACTFLEX PU300
hydrophobic foam urethane system
two-component polyurethane injection resin
ACTFLEX PU300 is a two-component polyurethane injection resin consisting of a base resin (10 parts) and an accelerator (1 part). This hydrophobic foam urethane system is designed for structural crack sealing and leak prevention, similar to ACTFLEX PU200. The separate accelerator component allows for precise control of reaction time, enabling adjustments based on site conditions such as ambient temperature, water flow rate, and substrate characteristics. This flexibility ensures optimal performance in varying environmental conditions, making it ideal for waterproofing, leak repair, and structural reinforcement applications.
