Applications
Silane GX-602 may be used as an additive, thereby eliminating the need for special primers in numerous bonding applications. Specific systems that demonstrate improved adhesion when silane GX-602 is used are:
RTV Silicones and Hybrid Silane-Crosslinked Sealants
Silane GX-602 addition to one- and two-part silicone-crosslinked sealants improves adhesion to a variety of substrates, including glass, aluminum and concrete. Silane GX-602 provides enhanced adhesion performance without negatively impacting elongation. It is added at a loading of 0.5 to 1.0 percent by weight.
Polysulfide Sealants
When added to one- and two-part polysulfide sealants, silane GX-602 provides better adhesion to a variety of substrates, including glass, aluminum and steel. Silane GX-602 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 GX-602 eliminates the need for primers normally required to achieve adhesion to surfaces.
Plastisol Sealants
Adding silane GX-602 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 GX-602modified systems have a very light color, and the cured compound is bubble-free.
Additive in Phenolic and Epoxy Molding Compounds
Silane GX-602, 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.
