Description

n-(3-Methacryloxy-2-Hydroxypropyl)-3-Aminopropyltriethoxysilane, 50% In Methanol is a high-performance, dual-functional organosilane coupling agent designed to enhance adhesion and durability in composite materials. Its unique molecular structure, featuring both methacrylate and amino groups, provides exceptional bonding between inorganic substrates and organic polymer matrices. This product is essential for manufacturers in the coatings, adhesives, sealants, and advanced composites industries seeking to improve mechanical strength, chemical resistance, and long-term performance.

Application

• Adhesion Promoter for Coatings: Significantly improves the adhesion of acrylic, epoxy, and polyurethane coatings to glass, metals, and mineral surfaces.
• Fiberglass & Composite Reinforcement: Acts as a critical sizing agent for glass fibers and mineral fillers in reinforced plastics (FRP), enhancing interfacial bonding and mechanical properties.
• Sealant and Adhesive Formulations: Used to boost the bond strength and moisture resistance of silicone, polyurethane, and MS polymer-based sealants and adhesives.
• Dental & Medical Composites: Serves as a key coupling agent in dental restorative composites and bone cements, ensuring strong filler-to-resin bonding.
• Rubber Compounding: Improves the reinforcement of silica-filled rubber compounds for tires and industrial rubber goods, reducing rolling resistance and improving wear.
• Ink and Pigment Treatment: Enhances the dispersion and stability of inorganic pigments and fillers in printing inks and specialty coatings.

Quality Control

Our production of this organosilane adheres to strict quality management systems. Every batch is analyzed to ensure consistent performance, with key parameters including silane content, methacrylate functionality, and solution stability. Certificates of Analysis (COA) documenting purity, assay, and identity are provided with each shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its highly volatile methanol solvent and light-sensitive nature, keep away from heat, sparks, and open flame. Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
