Product Information

Chemical Name：N-(β-AMINO ETHYL) -γ-AMINO PROPYL METHYL DIMETHOXY SILANE

Product Code：LT-602

Molecular Formula：C₈H₂₂N₂O₂Si

Molecular Weight：206

CAS NO.：3069-29-2 

Properties and Reactivity

◆ LT-602 It is an organosilane with an active amine group and a hydrolyzable methoxysilicon-free bifunctional group. This bifocal structure gives LT-602 special properties: it is able to organically bond inorganic materials (such as glass, metal, fillers) and organic polymers (such as thermoplastics, thermosets or elastomers) together, thus acting as a catalyst for adhesion, crosslinking agents and/or surface modifiers, reactants for product modification.

◆ It is a colorless or light yellow transparent liquid with a special ammonia taste, soluble in alcohols, chain hydrocarbons and aromatic hydrocarbons and other solvents.

◆ In the presence of water, LT-602 will hydrolyze the silicon hydroxyl groups that produce domestic waves, forming bonds on the surface of various inorganic materials. The amino groups of LT-602 with organic properties can react with suitable organic polymers.

◆ LT-602 can self-catalyze hydrolysis reaction. The PH value of the hydrolysate is about 10~11.

◆ Suitable inorganic materials like: glass, glass fiber, glass wool, mineral wool, silica, sand, mica, aluminum hydroxide, quartz, calcium silicate, kaolin, talc, other silicate fillers, metal oxides and metals.

◆ Resins that can be used for LT-602 include phenolic resin, furan, and silicone rubber.

◆ LT-602 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.
