Description

Silane, Trimethoxy[3-(Oxiranylmethoxy)Propyl]-, Reaction Products With Wollastonite (Ca(SiO3)) is a specialized organosilane-modified mineral composite designed to enhance the performance of polymer matrices. This product is engineered to provide superior interfacial adhesion and mechanical reinforcement in composite materials, addressing key challenges of filler dispersion and matrix compatibility. It is a critical additive for manufacturers in the advanced composites, coatings, and adhesives industries seeking to improve product durability and performance.

Application

• Polymer Composites: Acts as a coupling agent and reinforcing filler in epoxy, polyester, and polyurethane composites to improve tensile strength, flexural modulus, and impact resistance.
• Protective Coatings: Enhances the adhesion, corrosion resistance, and weatherability of industrial and marine coatings by promoting strong bonding between the inorganic pigment/filler and the organic resin.
• Adhesives & Sealants: Improves the bond strength, cohesion, and moisture resistance of structural adhesives, especially for bonding dissimilar materials like metals, glass, and plastics.
• Engineered Plastics: Used as a functional filler in engineering thermoplastics and thermosets to reduce shrinkage, improve dimensional stability, and enhance thermal properties.
• Rubber Compounding: Serves as a reinforcing agent in silicone and other specialty rubbers to improve tear strength and abrasion resistance.
• Electronic Encapsulants: Provides improved thermal conductivity and mechanical reinforcement in potting compounds and encapsulants for electronic components.

Quality Control

Our production of this advanced composite material adheres to a stringent quality management system. Every batch undergoes rigorous testing to ensure consistent performance as a high-performance coupling agent and reinforcement filler. Key parameters such as silane loading, particle size distribution, and epoxy functionality are monitored. A Certificate of Analysis (COA) detailing lot-specific results is provided with each shipment to guarantee compliance with your technical requirements.

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 product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption and caking. Separate from strong acids and bases.
