Silane Coupling Agent 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.

2. Formula: CH3(CH3O)SIC3H6NHC2H4NH2

3. Property and Index: Colorless transparent liquid.

CAS NO.: 3069-29-2

Molecular Weight: 206.36

Boiling Point: 265 C. Deg.

Physical form: Colorless, clear liquid

Color, Pt-Co: Max 30

Specific gravity at 20 C. Deg, g/cm3: 0.965~0.975

Refractive index, nD20 C. Deg.: 1.4440~1.4490

Purity: 95%min. & 97%min.

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.

5. Packing and storage:

(1) Packing: 25kg/pail or 200 kg/drum or other packing on request.

(2) This product must be sealed and kept in cool & ventilated place.
