BRB Silanil® 1479

by BRB International BV

BRB Silanil® 1479 by BRB International BV acts as an adhesion promoter. It is a silane co-oligomer that combines diamino and alkyl functional groups. It is designed to enhance adhesion between organic resins and inorganic materials such as concrete, glass and aluminum. The diamino group improves the adhesion performance with amino-reactive resins including MS polymer, silicone, silylated polyurethane, polyurethane, and epoxy while the alkyl chain side enhances hydrophobicity which provides better resistance to moisture. It improves the mechanical properties of adhesives by coupling inorganic fillers. BRB Silanil® 1479 reduces VOC emissions and odor during application and provides excellent wet adhesion performance. It improves elasticity with a lower modulus in cured adhesives. It is less yellowing compared to traditional diamino silanes and acts as a superior coupling agent in composites which enhances the mechanical properties of mineral-filled rubbers or resins. It is an ideal solution for applications requiring robust adhesion, hydrophobicity and enhanced durability in adhesives.
