Amino Silane Coupling Agent Crosile® 602

Amino Silane Coupling Agent Crosile® 602

N-[3-(Dimethoxymethylsilyl)propyl]ethylenediamine

 

Chemical Properties

A colorless or pale-yellow transparent liquid, soluble in many common organic solvents such as ethanol, aether, toluene, dimethylbenzene etc. Easily hydrolyzing after damped.

Crosile® 602 N(beta-aminoethyl) gamma-amino propyl methyl dimethoxy-silane, is diamino functional silans that may be used over a broad range of applications.

They are used to promote the adhesion of amino-reactive resins such as silicone, salivated polyurethane, two-part urethanes and two-part epoxies to inorganic surfaces, plastic surfaces, and inorganic fillers or reinforcements.

Application

Crosile® 602 may be used as an additive, so eliminating the need for special primers in numerous bonding applications. Crosile®602 can display a good adhesion in the following system:
1. RTV Silicones and Hybrid Silane-Crosslinked Sealants Crosile® 602 added to one and two-part silicone-crosslinked sealants improves adhesion to a variety of substrates, including glass, aluminum and concrete. 602 provides enhanced adhesion performance without negatively impacting elongation. It is added at a loading of 0.5 to 1.0 percent by weight.
2. Polysulfide Sealants When added to one and two-part polysulfide sealants, Crosile® 602 provides better adhesion to a variety of substrates, including glass, aluminum and steel. Crosile® 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 Crosile® 69 cannot use primers which enhance the adhesion strength between the coating.
3. Plastic Sealants Crosile® 602, as a replacement for Poly aminoamide adhesion promoters in plastic sealants, can improve bonding to metal substrates. In addition to increased strength, the silane-modified plastic sealant has a better appearance than a system that uses Poly aminoamide adhesion promoters. Crosile® 602 modified systems have a very light color, and the cured compound is bubble-free.
4. Additive in Phenolic and Epoxy Molding Compounds Crosile® 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.
