Solubility Silane Si-902 is completely and immediately soluble in water (with reaction), alcohol and aromatic and aliphatic hydrocarbons. Ketones are not recommended as diluents.
Applications and Performance Coatings, Adhesives and Sealants This aminosilane is an excellent adhesion promoter in acrylic coatings, adhesives and sealants. With polysulfide, urethane, RTV silicones, epoxy, nitrile, and phenolic adhesives and sealants, the product improves pigment dispersion and maximizes adhesion to glass, aluminum and steel.
Glass-Reinforced Resin Systems In glass-reinforced thermosets, silane Si-902 enhances the flexural, compressive and interlaminar shear strengths before and after exposure to humidity. This product greatly improves wet electrical properties. Glass-reinforced thermoplastics, polyamides, polyesters and polycarbonates exhibit increased flexural and tensile strengths before and after wet exposure when this silane is used.
Glass Fiber and Mineral Wool Insulation As a phenolic resin binder additive, silane Si-902 imparts moisture resistance and allows recovery after compression.
Mineral-Filled and Resin Systems SilaneSi-902 maximizes the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate and a host of other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix are also improved.
