BRB Silanil® 505

2-Aminoethyl-3-aminopropyltriethoxysilane. BRB Silanil® 505 by BRB International BV is an effective coupling agent for mineral-reinforced nylon 6, nylon 6/6 & polybutylene terephthalate and clay-reinforced elastomers such as natural and nitrile rubber. The silane-treated clay provides improvement in both physical and dynamic properties. It increases composite strength properties, wet & dry tensile strength & modulus and wet & dry flexural strength & modulus. It shows excellent adhesion promotion by diaminofunctional group in many kinds of adhesives e.g. silicone, epoxy, acrylic, polyurethane and silylated polyurethane to inorganic substrates such as metal & glass. BRB Silanil® 505 is recommended for fiber glass-reinforced phenolic, melamine and epoxy thermoset composites e.g. epoxy mold compound (EMC), either as a fiberglass finish or as a resinous additive. The recommended usage level is 1-2% for resin additive, 0.1-0.5% for glass fiber size process and 0.1-1.5% for mineral filler treatment.
