SiSiB epoxy Silane is a bifunctional organosilane widely used as adhesion promoters in epoxy, urethane, olyamides, acrylates, phenolics, melamine and polysulfide systems for coatings, adhesives and sealants industry and as coupling agent.

Silanes have the ability to form covalent bonds with inorganic substrates and epoxy resins. Most commonly, epoxycyclohexyl- and glycidoxy-functional silanes are used to pretreat fillers or are blended with the epoxy resin.

Figure 2 shows (via an SEM of the fracture surface) the difference in adhesion between a silica-filled epoxy resin with silane versus without silane. With silane, the epoxy coating on the silica particles is apparent; without silane, clean silica particles can be see in the epoxy matrix.

Siloxane and silicone diluents can reduce viscosity of epoxy systems as well as lower surface tension allowing ease of handling, facilitating higher filler loading and infiltration of prepregs and fine structural components.

These epoxy silanes are effective crosslinkers for resins that contain a functional group with an active hydrogen such as carboxylic acid or amine group. These epoxy silanes may be emulsified and their emulsions are easily blended with latexes …
