Acu-Seal Series - Vacuum Impregnation Resins

With Chem-Mat porosity sealing technology, a reliable sealing of castings, powder metal, molded plastic electrical parts, and other porous substrates can be achieved by using our specially formulated low viscosity sealants. Applying a vacuum impregnation technique, the liquid resins can fill internal micro- and macroscopic voids and cracks in ferrous and non-ferrous alloy castings as well as other metal and non-metal parts. The filled liquid can be cured in-situ to form solid thermoset plastic. These impregnated parts create leak-free assemblies that are capable of handling high pressure gas and fluid operations. We provide several grades for different curing methods such as anaerobic cure at room temperature or for heat cure processes at elevated temperatures. We also provide one grade with high solvent tolerance and temperature resistance.
