Description

Silane, Butyldimethyl(2-Methylpropoxy)- is a specialized organosilicon compound designed for advanced surface modification and coupling applications. This silane coupling agent is valued for its ability to create durable bonds between organic polymers and inorganic substrates, enhancing composite material performance. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material science for fillers and reinforcements.

Application

• As a coupling agent in mineral-filled composites (e.g., silica, clay) to improve dispersion and mechanical properties.
• Surface treatment for glass fibers and other reinforcements to enhance adhesion to polymer matrices.
• Primer or additive in adhesive and sealant formulations to improve bonding to difficult substrates.
• Hydrophobic modification agent for nanoparticles and pigments to prevent agglomeration and improve compatibility.
• Key intermediate in the synthesis of more complex silicon-based specialty chemicals.
• Used in waterproofing and protective coatings for construction materials.

Quality Control

Our production of Silane, Butyldimethyl(2-Methylpropoxy)- adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including GC, NMR, and purity assays, to ensure consistent performance and reliability. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
