Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 3-(Trimethoxysilyl)Propyl 2-Methyl-2-Propenoate CAS NO 26936-30-1 is a specialized silane-functional acrylic copolymer designed to provide superior adhesion and crosslinking capabilities. This advanced polymer is engineered to act as a high-performance coupling agent and adhesion promoter, creating durable bonds between organic polymers and inorganic substrates. It is essential for formulators and manufacturers in the coatings, adhesives, and sealants industries seeking to enhance product durability, chemical resistance, and mechanical strength.

Application

• Adhesion Promoter in Coatings: Significantly improves the adhesion of acrylic, epoxy, and polyurethane coatings to challenging substrates like metals, glass, and plastics.
• Crosslinking Agent for Sealants & Adhesives: Enhances the cohesive strength, weather resistance, and durability of high-performance sealants and structural adhesives.
• Surface Modification Agent: Used to treat fillers (e.g., silica, glass fibers) and pigments to improve their compatibility and dispersion within polymer matrices.
• Primer Formulations: A key component in primers for automotive, aerospace, and industrial applications where long-term corrosion protection and bond integrity are critical.
• Reinforcement of Composite Materials: Improves the interfacial bonding between resin and reinforcement in fiberglass and other composite systems.
• Waterborne System Modifier: Imparts enhanced water resistance and substrate wetting properties to environmentally friendly water-based formulations.

Quality Control

Our production of this silane-acrylic copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including silane content, molecular weight distribution, viscosity, and residual monomer levels to ensure consistent performance as an adhesion promoter. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can prematurely activate the silane functionality.
