Product information

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

METHOXY SILANE

Product Code：LT-792

Molecular Formula：C₈H₂₂N₂O₃Si

Molecular Weight：222.4

CAS NO.：1760-24-3

Properties

LT-792 is a colorless to yellowish liquid with a distinctive ammonia flavor that is

soluble in alcohols, chain hydrocarbons, and aromatic hydrocarbons.

LT-792 is a bifunctional silane with an active amino group and a hydrolyzable

non-methoxysilane. Due to the dual nature of its reaction, it is able to organically

bond inorganic materials (such as glass, metal, fillers) and organic polymers (such as

thermoplastics, thermosetting plastics or elastomers) together. It is used as a tackifier,

a surface modifier for organic/inorganic interfaces (anti-corrosion, primer) or as a

silicone polymer or crosslinking agent (moisture crosslinked polymer).

LT-792 as a coupling agent used in mechanical and electrical products can greatly

improve the water resistance, corrosion resistance and electrical properties (such as

volume resistivity, dielectric constant) of the product.

Technical data

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

Reactivity

◆ In the presence of water, LT-792 will hydrolyze the silicon hydroxyl groups that produce domestic waves, forming bonds on the surface of various inorganic materials.

◆ LT-792 has organic properties of diaminogroup can react with suitable organicpolymers.

◆ LT-792 can self-catalyze hydrolysis reaction. The PH value of the hydrolysate is

about 10, and in order to obtain a more stable hydrolysate, it is recommended that the PH value of the water be adjusted about 4. Suitable inorganic substrates include fiberglass, fiberglass fabrics, fillers (such as glass, mineral wool, mica, talc, wollastonite, kaolin, metal oxides, etc.).

◆ LT-792 can react with a variety of organic polymers, such as phenolic resin, furan resin, polystyrene, acrylic resin, polyvinyl chloride, nylon, melamine, silicone rubber, etc.

◆ LT-792 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

LT-792 is an important additive in many areas, such as:

◆ Glass fiber/electronic cloth composite material: can be used as glass fiber treatment agent, can also be used as infiltrating agent additive. 

◆ As a primer for glass and metal. 

◆ Casting resin: as an additive to various casting resins. 

◆ Sealants and adhesives: as primer or adhesion enhancers. 

◆ Inorganic filled polymers: pretreatments or additives for fillers and pigments. 

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

Other important benefits of the LT-792 include: Improved product performance, such as:

◆ The flexural strength, tensile strength, impact strength and elastomer modulus of the composite in both wet and dry conditions.

◆ Improved resistance to moisture and corrosion. 

Improve processing performance, such as:

◆ Adhesiveness. 

◆ Dispersivity.
