SiSiB® PC5011 can be used as a coupling agent to improve adhesion of organic resins to inorganic surfaces.

SiSiB® PC5011 can be used as an additive in a urethane adhesive formulation. Its addition to the isocyanate prepolymer causes no adverse effect in the prepolymer viscosity.

SiSiB® PC5011 can be used as a good coupling agent for epoxy resins to glass in laminates. The resin has good wet out on the treated glass fabric. More important, both flexural strength as well as wet and dry tensile strength are significantly improved over that seen with epoxy and amino functional silanes.

SiSiB® PC5011 can be used as an effective coupling agent for treating glass fabric used in polystyrene laminates. The flexural strength of these laminates is unchanged after two hours in boiling water, and the compressive strength slightly improved over that found under dry conditions.

SiSiB® PC5011 can be used as an intermediate for other functional organosilanes, such as SiSiB® PC1110, SiSiB® PC3100, SiSiB® PC4100 etc.
