KH-792 may be used as an additive, meeting the need of special primers in numerous bonding applications. KH-792 can display a good adhesion in the following system: RTV Silicones and Hybrid Silane-Crosslinked Sealants KH-792 silane coupling agent with single-double component silane-crosslinked sealant can improve the adhesion of many substrates, including glass, steel, aluminum and concrete. This silane can dramatically enhance the adhesion to a wide array of plastics when used in combination with SPURSM Technology for silyl urethane polymers. Polysulfide Sealants When silane KH-792 is added to single-double component polysulfide sealants, it provides better adhesion to a variety of substrates, including glass, aluminum and steel. Use dosage of Silane KH-792 is 0.5 to 1.0 percent of the sealant you use in general. It disperses well and can obtain cohesive split rather than interfacial split between the sealant and the substrate. Furthermore, the use of silane KH-792 can avoid using primers and it can enhance the adhesion strength between the coatings. Plastic sealant In plastic sealants treatment, silane KH-792(0.5 to 1.5 weight percent) as an adhesion promoter, a replacement for polyaminoamide, can improve bonding to metal substrates. In addition to increasing strength, the silane-modified plastic sealants have a better performance than systems those use polyaminoamide adhesion promoter. Silane KH-792-modified plastic systems have a very light color and the cured compound is bubble-free. Additive in Phenolic and Epoxy Molding Compounds Silane KH-792, as an additive in phenolic and epoxy molding compounds, reduces the water absorption of molded composites. So it can improve wet electrical properties, particularly at low frequencies. High-temperature strength properties are also improved.
