Impregnation Resins / Porosity Sealants

Impregnation Sealants for Porous Materials

Porosity in metal castings and powder metal parts can compromise performance, cause leaks, and lead to costly rework. Hernon’s advanced impregnation sealants for porous materials are engineered to seal internal micro-voids and surface porosity without altering part geometry or functionality.

Our impregnation resins for porosity sealing offer high penetration, excellent thermal and chemical resistance, and permanent sealing of leak paths. These solutions are ideal for a wide range of applications including die castings, sintered metals, and additively manufactured components.

Trusted by automotive, aerospace, and industrial manufacturers around the world, Hernon’s impregnation sealants increase production yield, reduce scrap rates, and extend the life and reliability of precision parts.

Benefits of Hernon Impregnation Resins:

• Seals micro-porosity and internal voids in metal parts
