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.

1. In the presence of water, the ethoxy groups of HENGDA-E8133 hydrolyze and form reactive silanol(Si-OH) groups which can bond to a variety of inorganic substrates. Upon hydrolysis ethanol is released. The organophilic amino group of HENGDA-E8133 can react with a suitable polymer.
2. The hydrolysis of HENGDA-E8133 takes place autocatalytically. Hydrolyzates could be stable for concentrations higher than 10% for >1 year. The pH of the aqueous solution is about 11.
3. Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool, silicic acid, quartz, cristobalite, wollastonite, mica as well as aluminum trihydrate, magnesium dihydrate, kaolin, talc, other silicate fillers, metal oxides and metals.
4. HENGDA-E8133 may be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, PS, nitril Kautschuk, polyester, acrylates and silicones.
5. HENGDA-E8133 can undergo reactions with ketone or ester solvents. Silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates and/or carbamates.Product modifications are possible through addition reactions with suitable monomeric or polymeric compounds(e.g. isocyanates, epoxides, etc.).

1. HENGDA-E8133 is supplied in 25 kg or 190 kg drums or 950kg containers.
2. The containers must remain tightly sealed during storage and kept in a cool, well aired place. The product should be protected against humidity.
3. In the unopened container the shelf life of HENGDA-E8133 is min.12 months from delivery.
