Chemical Name：N-(β-AMINO ETHYL) -γ-AMINO PROPYL METHYL DIMETHOXY SILANE
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.
Note: the above data is for reference only, cannot be as a technical specification.
LT-602 is an important component in many industrial applications, such as:
◆ As an additive to cooling cured phenolic resins and furan resins, improve their bending strength and extend their shelf life.
◆ Used as the raw material of amino functional siloxane complex.
◆ Casting resin: as an additive for cool-cured phenolic resin and furan resin.
◆ Sealants and adhesives: as primers or additives.
◆ Inorganic filled compounds: pretreatment for fillers or pigments or as additives to polymers.
◆ Paints and coatings: as primer or additive to improve adhesion to substrate.
The LT-602 also brings important capabilities to end products, including:
◆ Improve mechanical properties such as bending strength, impact strength and modulus of elastomers.
◆ Improve moisture resistance and corrosion resistance.
◆ Improve electrical properties, such as dielectric constant, volume resistivity.
Improve processing performance, such as:
