Applications
Silane USi-D***1 may be used as an additive, meeting the need of
special primers in numerous bonding applications.
USi-D***1 can display a good adhesion in the following systems:
RTV Silicones and Hybrid Silane-Crosslinked Sealants
Silane USi-D***1 can improve the adhesion of silicone-crosslinked
sealants to a variety of substrates, including glass, aluminum and
concrete. Silane USi-D***1 provides enhanced adhesion performance
without negative influence on rate of elongation. The addition is
0.5 to 1.0 percent of fillers by weight.
Polysulfide Sealants
When added to single-double component polysulfide sealants, silane
USi-D***1 provides better adhesion to a variety of substrates,
including glass, aluminum and steel. The addition of USi-D***1 is
typically 0.5 to 1.0 percent of the sealant by weight. It disperses
well in 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**9 can not use
primers which enhance the adhesion strength between the
coating.
Plastic Sealants
Silane USi-D***1, as a replacement of polyaminoamide adhesion
promoter in plastic sealants, can improve bonding to metal
substrates. In addition to increasing strength, the silane-modified
plastic sealants . Silane USi-D***1 modified systems have a very
light color and the cured compound is bubble-free.
Additive in Phenolic and Epoxy Molding Compounds
Silane USi-D***1, 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.
