Application:
1. Widely used in the fiberglass industry.
2. It can improve the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate, and many other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix can also be improved.
3. This silane can strengthen the bond between the phenolic binder and foundry sand in shell molding.
4. As a phenolic resin binder additive, the HENGDA-E8133 silane coupling agent can impart moisture resistance and allow recovery after compression.
5. HENGDA-E8133 is an excellent adhesion promoter for many coating, adhesive, and sealant systems. With polysulfide, urethane, RTV silicones, epoxy, nitrile, and phenolic adhesives and sealants, the product can improve pigment dispersion and adhesion to glass, aluminum, steel, and various other substrates.
