Impregnation Resins, Equipment, and Services

    IMPCO, Inc. is globally committed to producing high quality Vacuum Resin Impregnation Sealants and Equipment. We also manufacturer and install Wet Vacuum and Dry Vacuum/Pressure Impregnation Systems. IMPCO specialists engineer vacuum resin impregnation processes and implement unique equipment and resin designs to solve customer problems.  IMPCO installs these engineered systems into customer facilities, or where more economical, provides impregnation services through its job shop facilitiy located in Rhode Island.

    Our long experience in impregnation techniques and extensive line of impregnation sealants include both Anaerobic impregnation resins and Thermoset impregnation resins. Anaerobic impregnation resins cure or cross link in the absence of air at room temperatures.  They are ideal for sealing powdered metal parts and electrical connectors. Thermoset impregnation resins cure at elevated temperatures, generally at 195°F/90°C, have excellent chemical resistance and excel in sealing castings.

    We also offer room temperature curing Flexible Sealants that make Electrical Connectors completely water tight thereby preventing corrosion when used in severe conditions.
