Applications

 

silane 　Si-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  Si-602 is used are:

RTV Silicones and Hybrid Silane-Crosslinked Sealants

silane Si-602 addition to one- and two-part silicone-crosslinked sealants improves adhesion to a variety of substrates, including glass, aluminum and concrete.  Silane Si-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  Si-602　provides better adhesion to a variety of substrates, including glass, aluminum and steel. Silane　 Si-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　 Si-602 eliminates the need for primers normally required to achieve adhesion to surfaces.

Plastisol Sealants

Adding  silane　 Si-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 Si-602modified systems have a very light color, and the cured compound is bubble-free.

Additive in Phenolic and Epoxy Molding Compounds

Silane　 Si-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.
