Adhesives and Sealants Additives


Achieving proper adhesion of sealants and coatings may be a challenge on many hard-to-coat surfaces. But Momentive’s adhesive and sealant additives can help make them stick – even when demanding conditions like heat, humidity or chemical resistance are present. Our innovative materials help promote adhesion to glass, minerals, metals and more difficult substrates, including polyamide, sheet molding compound, acrylics and PVC. In addition, these products can enhance the properties of the materials with which they are mixed, providing increased elasticity, weatherability and durability.

Our diverse portfolio of adhesive and sealant additives react with a variety of organic and inorganic materials to deliver moisture-initiated crosslinking of resins, improved wet adhesion and primerless adhesion to many substrates for more effective and efficient processing. They may further improve processing by potentially enhancing the chemical resistance, thermal stability, creep resistance, hardness and durability of adhesives and sealants.

These cost-effective products address numerous adhesion issues facing the architecture, construction, packaging and converting, industrial production, transportation, automotive, and power transmission industries, among others. And they can be adapted to help meet our customers' unique needs, whether it's a wider application window or a faster cure at room temperature.  Our silane brands, including Silquest* silanes, CoatOSil* additives and SPUR+* prepolymers, are effective materials that can used to address a wide array of applications.

Discover how Momentive's adhesive and sealant additives can help you successfully and efficiently promote adhesion for your most challenging applications.
