GF9(Wacker) silane KH***2 finds use as an : • Adhesion promoter in
polysulfide, polyvinyl chloride plastisol, silicone tow-part
urethanes and epoxy adhesives and sealants • Additive in phenolic
and epoxy molding compounds • Additive to latex coatings, adhesives
and sealants • Adhesion promoter in one-part silylated urethane
adhesives and sealants based on organofuntional silane SPURSM
Technology. Features and Benefits Feature Benefit Polyamino
functionality · Provides reactive site for amino-reactive resins. ·
Good wetting of substrates. Trifunctional silane · Excellent
adhesion to inorganic substrates such as metal, glass, etc. ·
Superior adhesion to plastics when employed in SPUR
Technology-based adhesives or sealants. Typical Physical Propertie
Physical Form Clear liqui Color, Pt-Co max *5 Specific Gravity at
*0oC 1.**0 – 1.**0 Refractive Index at *0oC 1.***5 – 1.***0 Purity,
% *7.0 min Applications silane KH***2 may be used as an additive,
eliminating the need for special primers in numerous bonding
applications. Specific systems that demonstrate improved adhesion
when silane KH***2 is used are: RTV Silicones and Hybrid
Silane-Crosslinked Sealants Silane KH***2 addition to one- and
two-part silicone-crosslinked sealants improves adhesion to a
variety of substrates, including glass, steel, aluminum and
concrete. This silane can dramatically enhance adhesion to a wide
array of plastics when used in combination with SPURSM Technology
for silylating urethane polymers. (For formulation and silylated
prepolymer preparation information, please refer to Literature
bulletin #*********0, “Silquest Organofunctional Silanes –
Crosslinkers and Adhesion promoters for Urethane Adhesives and
Sealants.” Polysufide Sealants When added to one- and two-part
polysulfide sealants, silane KH***2 provides better adhesion to a
variety of substrates, including glass, aluminum and steel. Silane
KH***2 is typically used at a loading of 0.5 to 1.0 percent by
weight to the sealant. It disperses well 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 KH***2 can eliminate the need forprimers normally required
to achieve adhesion to surfaces. Plastisol Sealants Adding silane
KH***2(0.5 to 1.5 weight percent) 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
KH****-modified plastisol systems have a very light color, and the
cured compound is bubble-free. Additive in Phenolic and Epoxy
Molding Compounds Silane KH***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. High-temperature
strength properties are also improved.
