CFS-475 cas 65799-47-5 [Z-6044; KBM-402] is a difunctional epoxy silane. It has an epoxy functional group and two hydrolyzable alkoxy groups (dimethoxy) in its molecular structure. This dual reactivity allows it to pass through with inorganic The two-way chemical reaction between materials (glass, metal, filler) and organic polymers (thermosetting resins, plastics, elastomers) improves the degree of bonding, bonding and compatibility between the two, thereby improving the mechanical properties of resin-based composites Or improve the adhesive strength and water resistance of the resin coating. In different applications, it can be used as a coupling agent, adhesion promoter, curing agent, surface modifier for pigments and fillers, etc.
Compared with similar silanes with trialkoxy structure, its dialkoxy structure has one less reactive alkoxy group and crosslinking point, so its stability in water is better than that of trialkoxy products, but the stability of the product The cross-linking density should be low, the rigidity is slightly worse, the flexibility is slightly better, and the overall mechanical properties are slightly worse.
Applications
Used as an additive or formulated as a primer for coatings, inks, adhesives and sealants such as polyurethane, silicone, epoxy, phenolic, acrylic, polysulfide, urea-formaldehyde, etc., to improve the adhesion and corrosion resistance of resin coatings , weather resistance, water boiling resistance and scrub resistance, prolong the service life, and improve the dispersion and combination of pigments and fillers in the resin phase.
CFS-475 cas 65799-47-5 [Z-6044; KBM-402] is copolymerized with silicone monomers such as D4 and DMC to synthesize epoxy-containing silicone oil products.
Mineral filler or glass fiber filled plastic (PBT, nylon, etc.), rubber, resin (epoxy, etc.), used to improve the dispersion and bonding of fillers and fibers in the resin phase, and improve the mechanical strength of the product.
Surface treatment of inorganic mineral pigments and fillers (such as silicon micropowder, etc.), flame retardants (such as magnesium hydroxide, etc.) and glass fibers to improve their dispersion, compatibility, binding force and reinforcing effect in the resin phase.
