N (β-aminoethyl) γ-aminopropyltrimethoxy-silane finds use as an :
1. Adhesion promoter in polysulfide, polyvinyl chloride plastisol, silicone tow-part urethanes and epoxy adhesives and sealants
2. Additive in phenolic and epoxy molding compounds
3. Additive to latex coatings, adhesives and sealants
4. Adhesion promoter in one-part silylated urethane adhesives and sealants based on organofuntional silane SPURSM Technology.
Features and Benefits
1. Provides reactive site for amino-reactive resins.
2. Good wetting of substrates.
1.Excellent adhesion to inorganic substrates such as metal,glass, etc.
2.Superior adhesion to plastics when employed in SPUR Technology-based adhesives or sealants.
N (β-aminoethyl) γ-aminopropyltrimethoxy-silane may be used as an additive, eliminating the need for special primers in numerous bonding applications. Specific systems that demonstrate improved adhesion when N (β-aminoethyl) γ-aminopropyltrimethoxy-silane is used are:
1. RTV Silicones and Hybrid Silane-Crosslinked Sealants
N (β-aminoethyl) γ-aminopropyltrimethoxy-silane 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 #112-026-30, "Silquest Organofunctional Silanes – Crosslinkers and Adhesion promoters for Urethane Adhesives and Sealants."
2. Polysufide Sealants
When added to one- and two-part polysulfide sealants, N (β-aminoethyl) γ-aminopropyltrimethoxy-silane provides better adhesion to a variety of substrates, including glass, aluminum and steel. N (β-aminoethyl) γ-aminopropyltrimethoxy-silane 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 N (β-aminoethyl) γ-aminopropyltrimethoxy-silane can eliminate the need forprimers normally required to achieve adhesion to surfaces.
3. Plastisol Sealants
Adding N (β-aminoethyl) γ-aminopropyltrimethoxy-silane (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. N (β-aminoethyl) γ-aminopropyltrimethoxy-silane modified plastisol systems have a very light color, and the cured compound is bubble-free.
4. Additive in Phenolic and Epoxy Molding Compounds
N (β-aminoethyl) γ-aminopropyltrimethoxy-silane, 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.
