Ningbo Inno Pharmchem Co., Ltd. is a leading manufacturer of Momentive's Silquest A-166, a silane coupling agent that is widely used in a variety of industrial applications. This product has been gaining popularity in recent years due to its excellent chemical properties and versatile applications.

Silquest A-166 is an organosilane coupling agent that is used to improve the adhesion and durability of coatings, adhesives, and sealants. It is compatible with a wide range of substrates and can be used to improve the bonding of metals, plastics, ceramics, and composites. The product is also used as a surface treatment for glass fibers, mineral fillers, and other reinforcing materials to improve their compatibility with resins.

The chemical structure of Silquest A-166 is based on hexamethyldisiloxane (HMDS), which is a widely used siloxane compound in the chemical industry. HMDS is a clear, colorless liquid that is highly soluble in organic solvents and has a low boiling point of around 100°C. It is a versatile building block for the synthesis of a wide range of siloxane derivatives, including silanes, siloxanes, and silicones.

The unique chemical properties of Silquest A-166 are due to the presence of functional groups on the HMDS molecule that can react with a wide range of substrates. The product contains a vinyl group (-CH=CH2) and a methacryloxy group (-CH2C(CH3)=CH2) that can undergo free-radical polymerization reactions with unsaturated substrates. It also contains a trimethoxysilyl group (-Si(OCH3)3) that can hydrolyze and condense with silanol groups on the substrate surface to form a covalent bond.

The chemical reactivity of Silquest A-166 makes it an excellent coupling agent for a wide range of applications. It can improve the adhesion and mechanical properties of coatings, adhesives, and sealants on various substrates, including metals, plastics, ceramics, and composites. It can also improve the dispersion and wetting of fillers and pigments in coatings and plastics, leading to better color stability and opacity.

Silquest A-166 is supplied by Ningbo Inno Pharmchem Co., Ltd. as a clear, colorless liquid with a typical purity of 98%. It is available in various packaging sizes, including drums, totes, and bulk tankers, depending on the customer's requirements. The product is shipped worldwide to customers in the coatings, adhesives, sealants, and plastics industries.

The market for Silquest A-166 is growing rapidly, driven by the increasing demand for high-performance coatings, adhesives, and sealants in various industries. The product is used in a wide range of applications, including automotive, aerospace, construction, and electronics. It is also used in the production of composites, such as fiberglass-reinforced plastics (FRP), which have excellent mechanical properties and durability.

The main competitors of Silquest A-166 in the market are Evonik Degussa Dynasylan HMDS, DOWSIL Z-6079, Shin-Etsu Japan HMDS3, and Dynasylan HMDS from Evonik Industries. These products are also based on HMDS and have similar chemical properties and applications. However, Silquest A-166 has some unique advantages over its competitors, such as better compatibility with waterborne coatings and improved adhesion to low-energy surfaces.

In conclusion, Ningbo Inno Pharmchem Co., Ltd. is a leading supplier of Momentive's Silquest A-166, a versatile silane coupling agent that is widely used in the coatings, adhesives, sealants, and plastics industries. The product has excellent chemical properties and can improve the adhesion, durability, and mechanical properties of various substrates. The market for Silquest A-166 is growing rapidly, driven by the increasing demand for high-performance materials in various industries. With its unique advantages and competitive pricing, Silquest A-166 is an excellent choice for customers looking for a high-quality coupling agent.
