EPT-Sealer 685C is specially designed for water sealing applications where a good weatherability and long-term exposure at high temperatures are required. Depending on the applications, the foam needs to be compressed by 5-35% to activate its sealing properties.
AUTOMOTIVE – sealing of HVAC unit, dashboard, air duct, firewall, battery.
HOME APPLIANCE – sealing of refrigerators, driers, washing machines.
NEW ENERGY – sealing of heat pumps, air-conditioners, EV chargers, solar panels.
