silane coupling agent KH-550 - Names and Identifiers
silane coupling agent KH-550 - Introduction
Silane coupling agent KH-550, the chemical name is 3-amino propyl trimethoxy silane, is an organic silicon compound. It has the following properties:
1. Appearance: colorless to light yellow liquid.
2. Common chemical formula: CH3O-Si(CH2)2NH2(CH3)2. Wherein CH3O represents a methoxy group, Si represents Silicon, CH2 represents a methylene group, NH2 represents an amine group, and (CH3)2 represents two methyl groups.
3. Density: about 0.97 g/cm.
4. Boiling Point: about 140-143 ° C.
5. Melting Point: about -50 ° C.
6. Solubility: Soluble in organic solvents, such as alcohol, ether, etc.
KH-550 main uses of silane coupling agent are as follows:
1. As a surfactant: it can be used to improve the compatibility of fillers, ceramic powders and other materials with resins, and improve the wear resistance, durability and bonding strength of materials.
2. As a coupling agent: it can be used to improve the interfacial adhesion between filler and rubber, plastic and other materials, and improve the strength, hardness and corrosion resistance of the material.
3. As an improver: it can be used in coatings, inks and other products to improve the adhesion, durability and weather resistance of coatings and substrates.
Silane coupling agent KH-550 are generally synthesized by Silylation reaction. The specific step is to react 3-aminopropyltrimethylchlorosilane with methanol to generate KH-550. The reaction conditions include suitable temperature, reaction time and catalyst, etc.
For KH-550 safety information, here are some suggestions:
1. Comply with chemical safety operation specifications: During use, please comply with chemical safety operation specifications, including wearing protective gloves, glasses and other protective equipment.
