APPLICATIONS:
silane RJ-Si602 finds use as an:
• Adhesion promoter in polysulfide, polyvinyl chloride plastisol, silicone, one- and two-part urethanes, and epoxy adhesives and sealants
• Additive in phenolic and epoxy molding compounds
• Additive to latex coatings, adhesives and sealants

1.RTV Silicones and Hybrid Silane-Crosslinked Sealants
silane RJ-Si602 addition to one- and two-part silicone-crosslinked sealants improves adhesion to a variety of substrates, including glass, aluminum and concrete. Silane RJ-Si602 provides enhanced adhesion performance without negatively impacting elongation. It is added at a loading of 0.5 to 1.0 percent by weight.

2.Polysulfide Sealants
When added to one- and two-part polysulfide sealants, silane RJ-Si602 provides better adhesion to a variety of substrates, including glass, aluminum and steel. Silane RJ-Si602 is typically used at a loading of 0.5 to 1.0 percent by weight of the sealant. It disperses well into the sealant and produces cohesive failure in the sealant rather than adhesive failure of the bond between the sealant and the substrate. Furthermore, the use of silane RJ-Si602 eliminates the need for primers normally required to achieve adhesion to surfaces.

3.Plastisol Sealants
Adding silane RJ-Si602 as a replacement for polyaminoamide adhesion promoters in plastisol sealants improves bonding to metal substrates. In addition to increased strength, the silane-modified plastisol sealant has better overall appearance than a system that uses polyaminoamide adhesion promoters. silane RJ-Si602 modified systems have a very light color, and the cured compound is bubble-free.

4.Additive in Phenolic and Epoxy Molding Compounds
Silane RJ-Si602, as an additive in phenolic and epoxy molding compounds, reduces the water absorption of molded composites. This, in turn, leads to improved wet electrical properties, particularly at low frequencies.
