Max *5 Applications silane Si***2 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***2 is used are: RTV Silicones and Hybrid
Silane-Crosslinked Sealants silane Si***2 addition to one- and
two-part silicone-crosslinked sealants improves adhesion to a
variety of substrates, including glass, aluminum and concrete.
Silane Si***2 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***2 provides better
adhesion to a variety of substrates, including glass, aluminum and
steel. Silane Si***2 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***2 eliminates the need for
primers normally required to achieve adhesion to surfaces.
Plastisol Sealants Adding silane Si***2 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***2modified systems have a very light color, and the cured
compound is bubble-free. Additive in Phenolic and Epoxy Molding
Compounds Silane Si***2, 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.
