HENGDA-M5132 - 3-Chloropropylmethyldimethoxysilane

HENGDA-M5132

3-Chloropropylmethyldimethoxysilane is a chemical compound with the molecular formula (CH₃O)₂Si(CH₂)₃CHClCH₃. This organosilane consists of a silicon atom bonded to a methyl group, a 3-chloropropyl group, and two methoxy groups. It is commonly used as a coupling agent and surface modifier in various industrial applications, similar to other silanes. Its primary function is to enhance the adhesion and compatibility between organic polymers and inorganic surfaces such as glass, metals, or silica. This compound can be used in coatings, adhesives, sealants, and as a primer in applications where improved bonding strength and durability are required.

Applications

1. This product is an intermediate with a wide range of uses. 3-Chloropropylmethyldimethoxysilane can be used to prepare a variety of coupling agents, and can also be used to prepare special silicone oil.

2. In the rubber industry, the strength of polyurethane elastomers can be improved by introducing polar groups (chloropropyl groups); It can also be used to synthesize vulcanized rubbers with lower permeability, rolling resistance, higher elasticity and elongation; It can be used as a bulletproof solid tire in the military.

3. In the plastic industry, it can effectively inhibit the dialysis of polyvinyl chloride (PVC) plasticizers, and keep PVC clean and hygienic for a long time; it can be used as an absorbent for polyurethane foams to improve the weather resistance of foams.

4. In the textile industry, 3-Chloropropylmethyldimethoxysilane can be made into a fabric treatment agent to make the fabric soft and elastic; It can also prevent the fabric from yellowing and improve the dyeing performance of the fabric.

5. In the printing industry, it can be made into a negatively charged toner for electrostatic copying, image development, etc.
