Application of silane coupling agent is generally three ways:
First, as a reinforcing material surface treatment agent; second is added to the adhesive, the third is added directly to the polymer material. From its full effectiveness and cost point of view, the first two methods better.
Application of silane coupling agent can be broadly divided into three areas:
1.For the surface treatment of glass fiber can improve the adhesion properties of glass fiber and resin, thereby greatly increasing the strength of glass fiber reinforced composite materials, electric, water resistant, weather-resistant properties,Even when wet, to improve its mechanical properties of composite materials, the effect is very significant.Use glass fibers with a silane coupling agent is quite common for this aspect of the silane coupling agent accounts for about 50% of its total consumption,Which used more variety is vinyl silane, amino silane, methacryloxy silane.
2.Inorganic fillers for plastics.Can be pre-filler surface treatment can also be directly added to the resin.Can improve the filler in the resin dispersion and adhesion, improving process performance and improve filled plastics (including rubber) mechanical, electrical and weather resistance and other properties.
3.As sealants, adhesives and coatings thickener, can improve their adhesive strength, water resistance, weather resistance and other properties.Silane coupling agents can often be unable to resolve some long-standing material bonding problems.
