Unrivaled Sealing Performance

Thermal-cure sealants are commonly used to seal micro-porosity in castings. They cure quickly when heated to 195° F (90°C), allowing parts to be pressure-tested in either continuous-flow or transfer-line type applications.

These sealants are also optimal for the Dry Vacuum and Pressure (DVP) impregnation process.

Fully Recoverable

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 allows for ease of use, longer pot life and stable properties.


Cost Effective

Recoverable sealants remain pure in its original formulation throughout the manufacturing process.

Retaining and using pure sealant means no additives or excessive maintenance is needed. Resulting in the highest possible part quality while reducing cost and maintenance time.


Approved by OEMs Worldwide

Godfrey & Wing’s thermal-cure sealants are approved by OEMs worldwide. The world’s leading manufacturers trust that Godfrey & Wing’s sealants are repeatable and sustainable.
