Chemical Name：N-（β-AMINO ETHYL)-γ-AMINO PROPYL TRI METHOXY SILANE

Molecular Formula：C₈H₂₂N₂O₃Si

Molecular Weight：222.4

CAS No.：1760-24-3

Properties

BOSIL-176A is a bifunctional silane with active amino groups and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reaction, it can organically bond inorganic materials (such as glass, metals, fillers) and organic polymers (such as thermoplastics, thermosetting plastics or elastomers). It is used as a tackifier, surface modifier for organic/inorganic interface (corrosion protection, primer) or silicone polymer or crosslinking agent (moisture crosslinking polymer).

BOSIL-176A used as a coupling agent in mechanical and electrical products can greatly improve the product's water resistance, corrosion resistance and electrical properties (such as volume resistivity, dielectric constant).

BOSIL-176A is a colorless to light yellow liquid with a special ammonia smell, soluble in alcohols, chain hydrocarbons, aromatic hydrocarbons and other solvents.

Technical Data

Note: the above data is for reference only, cannot be as a technical specification.

Reactivity

In the presence of water, B-176A will hydrolyze the silicon hydroxyl groups that generate active waves, forming bonds on the surface of various inorganic materials.

B-176A has organic properties of diamino group can react with suitable organic polymer.

B-176A can autocatalyze hydrolysis reaction. The PH value of the hydrolysate is about 10. In order to obtain a more stable hydrolysate, it is recommended to adjust the pH of the water to about 4. Suitable inorganic substrates include glass fibers, glass fiber fabrics, fillers (such as glass, mineral wool, mica, talc, wollastonite, kaolin, metal oxides, etc.).

B-176A can react with various organic polymers, such as phenolic resin, furan resin, polystyrene, acrylic resin, polyvinyl chloride, nylon, melamine, silicone rubber, etc.

B-176A can react in ketone or ester solvents. The silane itself or the silanized substrate reacts with carbon dioxide to form the corresponding carbonate or carbamate.

Application

BOSIL-176A is an important additive in many fields, such as：

◆ Fiberglass/electronic cloth composite material: it can be used as glass fiber treatment agent, and can also be used as wetting agent additive

◆ As a primer for glass and metal

◆ Casting resin: as a variety of casting resin additives

◆ Sealant and adhesive: used as primer or adhesion promoter

◆ Inorganic filled polymer: pretreatment agent or additive for fillers and pigments

◆ Paints and coatings: as an additive or primer to improve the adhesion to the substrate

The important function of B-176A is also: to improve product performance, such as：

◆ The bending strength, tensile strength, impact strength and elastic modulus of the composite material in dry and wet conditions。

◆ Improve moisture resistance and corrosion resistance

Improve processing performance, such as：

◆ Adhesion

◆ Dispersion
