Detailed Product Description

Silane Coupling Agent AH-602

Corresponding trademark in abroad: KBM-602, A-2120

1. Chemical Name: N-(beta-Aminoethyl)-gamma-aminopropylmethyl-dimethoxysilane, It is a  

    diamino functional silane that maybe used over a broad range of applications. It is used to 

     promote adhesion between inorganic and organic surfaces, fillers or reinforcements and

     resins that react with amino groups.

Features:

    Polyamino functionally: Reactive group for coupling with a variety of resins.

    Good stability in substrates.

    Difunctionally silane: Good stability in watertborne systems.

    Improves adhesion while maintaining elongation of elastomeric systems.

    Improved shelf-life of formulated products.

4. Application:

   (1) It can be used as adhesion promoter in polysulfide, polyvinyl chloride plastisol, sillcone,  

        one-and two-part urethanes, and epoxy adhesives and sealants.

   (2), as additive in phenolic and epoxy molding compounds, also can be used as additive to 

        latex coatings, adhesives and sealants

        Silane 602 may be used as an additive, eliminating the need for special primers in

        numerous bonding applications.

Specific systems that demonstrate improved adhesion Silane 602 used are:

A), RTV silicones and hybrid silane-crosslinked sealants

      Silane 602 addition to one-and tow-part silicone-crosslinked sealants improves adhesion

      to a variety of substrates, including glass, aluminum and concrete. Silane 602 provides

      enhanced adhesion performance without negatively impacting elongation. It is added at a

      loading of 0. 5 to 1. 0 percent by weight.

B), Polysulfide sealants

     When added to one-and two-part polysulfide sealants, Silane 602 provides better adhesion

     to a variety of substrates, including glass, aluminum and steel. Silane 602 is typically used

     at a loading of 0. 5to 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 602 eliminates the

     need for primers, Normally required to achieve adhesion adhesion to surfaces.

C), Plastisol sealants

     Adding Silane 602 as a replacement for polyaminoamide adhesion promoters in plastisol

     sealants improves bonding to metal substrates. In addition to increased strength, the

     silane modifiedd plastisol sealant adhesion promoters. Silane 602modified systems have a

     very light color, and the cured compound is bubble-free.

     Additive in phenolic and epoxy molding compounds,

     Silane 602, as an additive in phenolic and epoxy molding compounds, reduces the water 

     absorption of molded composites. This, in turn, leads to improves wet electrical properties,

     particularly at low frequencies.
