BRB Silanil® 919

BRB Silanil® 919 is a reactive chemical containing an aminopropyl organic group and a triethoxysilyl inorganic group. CAS# is specified as 919-30-2.

Chemically, BRB Silanil® 919 is designated gamma aminopropyltriethoxysilane. Possessing both organic and inorganic reactivity, BRB Silanil® 919 can react with organic resins and elastomers as well as with the surface of inorganic materials such as fiberglass and silica.

• Improves adhesion
• Increases composite strength properties
• Increased composite wet and dry tensile strength and modulus
• Increased composite wet and dry flexural strength and modulus
• Increased wet and dry compressive strength
• Increased transparency of fiberglass composites

• Good coupling agent to improve adhesion of many plastics, resins, and elastomers to inorganic materials and surfaces
• Very useful for improving the properties of mineral-filled rubber
• Proven additive for foundry resins as a coupling agent to provide moisture resistance and better mechanical properties
• Effective coupling agent to modify functional group on glass fiber surface during size process
