Description

Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Reaction Products With Me Hydrogen Siloxanes And Trimethoxy3-(Oxiranylmethoxy)Propylsilane is a specialized, multi-functional silicone-based polymer designed for advanced material formulations. This compound is engineered to deliver enhanced cross-linking efficiency and adhesion promotion in demanding industrial applications. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to improve product performance and durability.

Application

• Cross-linking Agent for Silicone Elastomers: Used to enhance the mechanical strength, thermal stability, and chemical resistance of high-performance silicone rubbers.
• Adhesion Promoter in Coatings and Inks: Improves bonding to difficult substrates like metals, glass, and plastics, particularly in UV-curable and epoxy-based systems.
• Reactive Modifier for Epoxy Resins: Imparts flexibility, impact resistance, and reduced internal stress in cured epoxy networks for composite and electronic applications.
• Key Component in Sealant and Adhesive Formulations: Provides excellent weatherability, moisture resistance, and long-term durability for construction and automotive sealants.
• Surface Treatment Agent: Used to modify surface properties of fillers and pigments to improve dispersion and compatibility in polymer matrices.
• Intermediate for Specialty Silicone Synthesis: Serves as a building block for creating custom silicone copolymers with tailored properties.

Quality Control

Our production of this advanced silicone intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including FT-IR for structural confirmation, viscosity measurement, and epoxy equivalent weight determination, to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
