Description

Silane, Dichloromethyl-, Reaction Products With Polybutadiene And Polyethylene-Polypropylene Glycol Mono-Bu Ether is a specialized organosilicon compound engineered as a reactive coupling agent and adhesion promoter. This product is critical for enhancing the compatibility and bonding strength between inorganic fillers and organic polymer matrices. It is primarily utilized by formulators in the rubber, sealant, adhesive, and advanced composite materials industries seeking to improve mechanical properties and durability.

Application

• As a coupling agent for silica and other mineral fillers in high-performance rubber compounds, including tires and industrial belts.
• To improve adhesion and moisture resistance in sealants, adhesives, and coatings, particularly for automotive and construction applications.
• As a surface modifier for nanoparticles and fibers in advanced polymer composites to enhance interfacial strength and dispersion.
• In the formulation of release coatings and mold-making materials where controlled surface energy is required.
• As a key ingredient in primer systems for bonding plastics, glass, and metals.
• For the hydrophobization of surfaces and fillers to prevent moisture-induced degradation in final products.
