3-(2-Aminoethylamino)propyl-dimethoxymethylsilane

Aminoethyl aminopropyl methyldimethoxy-silane is a diaminodialkoxy silane, commonly known as KH-602 or silane 602. Its molecular structure contains two amino (a primary amino group and a swelling amino group) functional groups and two hydrolyzed alkoxy - methoxy group. This dual reactivity enables it to improve the degree of binding, bonding and compatibility between inorganic materials (glass, metal, filler) and organic polymers (thermosetting resins, plastics, elastomers) through two-way chemical reactions. Then the mechanical properties of resin matrix composites or the bonding strength and water resistance of resin coatings can be improved. In different applications, it can be used as coupling agent, adhesion enhancer, curing agent, surface modifier of fillers, etc.

Aminoethyl aminopropyl methyldimethoxy-silane is dimethoxy-silane, so its stability in water is better than trimethoxy-silane SCA-A20M; At the same time, the crosslinking density of cured crosslinking resin coating is lower and the coating toughness is better.

Product physical indicators:

Use and effect：

1. as an additive or prepared into the bottom coating liquid and used in phenolic aldehyde, urea aldehyde, furan, polyurethane, silicone, epoxy, nitrile, phenolic, acrylic and other coatings, ink, adhesives and sealants, to improve the adhesion of resin coating, corrosion resistance, weather resistance, boiling resistance and scrub resistance, prolong the service life, and improve the dispersion and bonding of the makeup, filler in the resin phase.

2. Resin sand casting and resin abrasives are used to improve the binding force and water resistance of resin and silica sand or abrasive.

3. mineral filler or glass fiber filled plastic, rubber, resin and low smoke halogen-free flame retardant cable material to improve the dispersion and combination of filler and fiber in the resin phase.

4. inorganic mineral filler, flame retardant and glass fiber surface treatment, to improve its dispersibility, compatibility, binding force and enhance the effect in the resin phase.

Storage：

Store indoors away from light, keep ventilated, cool and dry. Make sure the lid is well sealed and effectively keeps out the air. Moisture in the air will react with it, causing it to hydrolyze, polymerize and deteriorate.
