Silane coupling agents are produced by the alcoholysis of silane chloroform (HSiCl3) and unsaturated olefins with reactive groups in a platinum chloroacid catalysed addition.
Through the use of silane coupling agent, inorganic substances and organic substances can be set up between the interface of the "molecular bridge", the two nature of the material connected together, to improve the performance of the composite material and increase the role of adhesive strength. This characteristic of silane coupling agent was firstly applied to glass fibre reinforced plastics (FRP) as the surface treatment agent of glass fibre, so that the mechanical properties, electrical properties and anti-ageing properties of FRP have been greatly improved, and the importance of the FRP industry has long been acknowledged.
At present, the use of silane coupling agent has been expanded from glass fibre reinforced plastic (FRP) to glass fibre surface treatment agent for glass fibre reinforced thermoplastic (FRTP), surface treatment agent for inorganic fillers, as well as sealants, resin concrete, water crosslinked polyethylene, resin encapsulation materials, shell moulding, tyres, belts, coatings, adhesives, abrasive materials (grinding stones) and other surface treatment agents. The following are some of the most common surface treatments.
