Anaerobic Sealants

Anaerobic sealants are best for powdered metal and overmolded electrical components. Because they cure at room temperature with no heat, they’re ideal for impregnating components with dissimilar materials that have varying coefficients of thermal expansion. These sealants are optimal for the Wet Vacuum (WV) process.


All Godfrey & Wing sealants are recoverable. Their use improves part sealing, maintains purity of the impregnation process and eliminates risk of sealant contamination. Use of recoverable sealants allow for ease of use, longer pot life and stable properties.
