Al2Chem

Al2Chem AL 121 Silane is utilized as a polymer modifier in grafting reactions, introducing pendant trimethoxysilyl groups that serve as moisture-activated crosslinking sites. The silane-grafted polymer is processed thermoplastically, with crosslinking occurring upon moisture exposure after the fabrication of the finished product.

Al2Chem AL 150 Silane is an amino-functional coupling agent designed to enhance bonding between inorganic substrates and organic polymers. Its silicon-containing portion ensures strong adhesion to substrates, while the primary amine function reacts with various thermoset, thermoplastic, and elastomeric materials.

Al2Chem AL 151 Silane is a clear, colorless, strongly alkaline liquid with low chloride content and high sensitivity to hydrolysis. It serves as an adhesion promoter at organic/inorganic interfaces, surface modifier for corrosion prevention, and moisture crosslinker for silicone polymers. As a coupling agent, it enhances mechanical and electrical properties, particularly under heat and moisture exposure.

Al2Chem AL FS-200 Fumed Silica Fumed Silica is a high-purity, amorphous, colloidal silica in the form of a fluffy white powder with nano-sized primary particles. It is widely used for its versatility, offering benefits such as thickening, reinforcement, free-flow enhancement, and anti-settling in various formulations.

Al2Chem AL 160 Silane is a bifunctional organosilane with a reactive epoxide group and methoxysilyl groups. It serves as an adhesion promoter and coupling agent, enhancing adhesion by chemically bonding to both inorganic materials and organic polymers. It is used in fiberglass reinforced composites, epoxy and urethane coatings, and as an adhesive and sealant in polysulfide, acrylic, and urethane applications. It is a liquid with compatibility in epoxies and silane-based systems.

Al2Chem AL FS-900 Fumed Silica Fumed Silica is a hydrophilic fumed silica treated with dimethyldichlorosilane (DMDS) to create a hydrophobic surface. This high-purity, amorphous, colloidal silica in fluffy white powder form features nano-sized primary particles. It provides benefits such as thickening, reinforcement, free-flow enhancement, and anti-settling, along with added water repellency, corrosion resistance, and thickening of complex liquid systems.

Al2Chem AL FS-800 Fumed Silica Fumed Silica is a hydrophilic fumed silica treated with polydimethylsiloxane to create a hydrophobic surface. This high-purity, amorphous, colloidal silica in fluffy white powder form features nano-sized primary particles. It offers benefits such as thickening, reinforcement, free-flow enhancement, and anti-settling, along with added water repellency, corrosion resistance, and thickening of complex polar liquids.
