Description

Silane, Dimethyl(3-Methylbutoxy)(1-Methylethyl)- is a specialized organosilicon compound with the CAS number 958997-78-9. This silane derivative is valued for its role as a versatile coupling agent and surface modifier, enhancing the compatibility and adhesion between organic polymers and inorganic substrates. It is primarily needed by manufacturers in the silicone rubber, adhesive, sealant, and composite materials industries where interfacial bonding is critical for performance.

Application

• As a coupling agent in mineral-filled composites (e.g., silica, clay) to improve dispersion and mechanical properties.
• As a surface treatment agent for glass fibers and other inorganic fillers to enhance bonding with polymer matrices.
• In the formulation of silicone sealants and adhesives to improve adhesion to various substrates.
• As an intermediate in the synthesis of more complex organosilicon molecules and functional materials.
• For hydrophobization of surfaces in coatings and construction materials.
• In the production of release coatings and mold-making materials within the rubber and plastics industry.

Quality Control

Our Silane, Dimethyl(3-Methylbutoxy)(1-Methylethyl)- is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed after opening to minimize exposure to moisture and prevent evaporation. Keep away from heat, sparks, and open flame.
