Product Description
HENGDA-E8133 CAS No.: 919-30-2 is a bifunctional silane possessing a reactive primary amino group and hydrolyzable ethoxysilyl groups.
The dual nature of its reactivity allows HENGDA-E8133 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers) thus functioning as an adhesion promoter, crosslinker, and/or surface modifier.
HENGDA-E8133 is a colorless to slightly yellowish low-viscosity liquid with an amine-like odor. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons.
HENGDA-E8133 is completely and immediately soluble in water (with reaction).

Applications:
1.Widely used in 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. In shell molding, this silane can strengthen the bond between the phenolic binder and foundry sand.
4. As a phenolic resin binder additive, HENGDA-E8133 silane coupling agent can impart moisture resistance and allow recovery after compression.
5. HENGDA-E8133 is an excellent adhesion promoter to consider for use in 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.
Reactivity:
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.
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.
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.
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.
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.).
Storage and shelf life:
HENGDA-E8133
is supplied in 25 kg or 190 kg drums or 950kg containers.
The containers must remain tightly sealed during storage and kept in a cool, well aired place. The product should be protected against humidity.
In the unopened container the shelf life of
HENGDA-E8133
is min.12 months from delivery.
