Description

Vinylethoxysiloxane Homopolymer is a reactive organosilicon polymer characterized by its vinyl and ethoxy functional groups. This compound is a key intermediate and cross-linking agent valued for its ability to modify surface properties and enhance the performance of silicone-based materials. It is primarily utilized by manufacturers in the adhesives, sealants, coatings, and specialty polymer industries seeking to improve adhesion, durability, and thermal stability.

Application

• As a cross-linking agent in silicone rubber and RTV (Room Temperature Vulcanizing) sealants.
• Surface modification of inorganic fillers (e.g., silica, glass) to improve compatibility with organic polymer matrices.
• A key intermediate in the synthesis of more complex silicone resins and modified siloxanes.
• Used in the formulation of release coatings and pressure-sensitive adhesives.
• Enhances the water repellency and weather resistance of construction and protective coatings.
• Acts as an adhesion promoter in composite materials and electronic encapsulants.
• Employed in the production of specialty polymers with tailored mechanical and surface properties.

Quality Control

Our Vinylethoxysiloxane Homopolymer is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency and meets agreed-upon specifications for parameters such as viscosity, vinyl content, and ethoxy group content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance.

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 (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, and open flame.
