Silane coupling agent KH-560 (CG-O187) features and uses
Silane coupling agent KH-560 (CG-O187) features and uses
Folding coatings, adhesives and sealants
Folded glass fiber reinforcement
In the glass fiber reinforced thermosetting and thermoplastic use, the silane coupling agent CG-O187 can greatly improve the dry and wet bending strength, tensile strength and interlaminar shear strength, and significantly improve the wet electrical performance. The use of this silane in dry and wet conditions increases the flexural strength and tensile strength of glass-fiber reinforced thermoplastics, polyamides, polyesters and polycarbonates both before and after immersion.
Folded fiberglass and mineral wool insulation
The addition of a silane coupling agent CG-O187 to the phenolic resin binder improves the moisture resistance and the resilience after compression.
Foldable mineral fillers and resin systems
Silane coupling agent CG-O187 can greatly improve the physical and mechanical properties and electrical properties of inorganic filler filled phenolic resin, polyester resin, epoxy, polyamine, polycarbonate and other thermoplastic and thermosetting resins and improve the filler in the polymer In the wetting and dispersibility.
Folding casting applications
The use of silane coupling agent CG-O187 can reduce the silica sand casting mold phenolic resin or furan resin bonding agent can be reduced, and to increase the strength of molding sand, gas evolution is also reduced.
Folding resin grinding wheel manufacturing
Silane coupling agent CG-O187 helps to improve the self-hardening sand and phenolic adhesive adhesion and water resistance.
The Application of Folding Wood Plastic
The mechanical properties such as impact strength, flexural strength and flexural modulus of the composites treated with silane coupling agent CG-O187 were improved.
In addition, surface chemical modification of quartz powder or other silica powder mainly uses various silane coupling agents such as amino group, epoxy group, methacryl group, trimethyl group, methyl group and vinyl group. The -RO functionality of the silane coupling agent can be hydrolyzed in water (including the free water adsorbed on the surface of the filler) to produce a silanol group which can be chemically bound to SiO2 or integrated with the original silanol groups on the surface , A homogeneous system. In this way, both the water on the SiO2 surface and the silicon-ether bond between the oxygen atoms are removed, and the organic functional group-R, which has a good affinity with the high molecular polymer, carried at the other end of the silane coupling agent 'Firmly covering the surface of the silica or silica particles to form a reactive coating film.
