Silquest™ A-172NT

Silquest™ A-172NT Silane by Momentive is a vinyl tris (2 methoxy-ethoxy) silane. It is used in glass fiber size binders. It is a vinyl-functional coupling agent that promotes adhesion among unsaturated, polyester-type resins or crosslinked polyethylene resins or elastomers and inorganic substrates. Improves electrical properties and strength of mineral-filled ethylene/propylene rubber and crosslinked polyethylene and other polymer or resin systems, particularly after wet-conditioning. Enhances the strength performance of cured, filled, or reinforced polyester and other resin composites, both initially and after wet conditioning. Improves the bond of glass filament to polyester and other resins in fiberglass reinforced applications, rendering the cured composites more resistant to wet environmental conditions. Improves the adhesion of silicone rubber applied to polyester or glass surfaces, especially important in high-temperature applications. Reduces water absorption in cured polyester molding compounds, particularly diallyl phthalate compounds, thus improving the wet electrical and mechanical properties. Silquest™A-172NT silane can be added to the clay and siliceous filler or blended directly into the system.
