Description

Siloxanes and Silicones, di-Me, hydroxymethyl group-terminated, polymers with adipic acid, 5-amino-1,3,3-trimethylcyclohexanemethanamine, 1,4-butanediol and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane is a specialized, high-performance polyurethane-modified silicone copolymer. This compound is engineered to deliver a unique balance of flexibility, thermal stability, and chemical resistance, making it a critical advanced material for demanding industrial applications. It is primarily sought after by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries who require enhanced performance characteristics.

Application

• High-Performance Coatings: Used as a key additive or resin component in industrial, automotive, and marine coatings to improve flexibility, weatherability, and surface slip.
• Specialty Adhesives & Sealants: Imparts durability, moisture resistance, and excellent adhesion to difficult substrates in construction and assembly applications.
• Advanced Elastomers: Serves as a base polymer for manufacturing silicone-polyurethane hybrid elastomers with superior mechanical and thermal properties.
• Fiber & Textile Treatment: Applied as a softener or finishing agent to provide durable, smooth hand feel and water repellency to technical textiles.
• Release Coatings: Formulated into non-stick release liners for pressure-sensitive adhesives and industrial molding processes.
• Polymer Modification: Acts as a compatibilizer or impact modifier in polymer blends to enhance toughness and processing characteristics.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems. Each batch is characterized using advanced analytical techniques to ensure consistency in molecular weight, functionality, and viscosity. Certificates of Analysis (COA) detailing key specifications are provided with every shipment to guarantee the material meets your formulation 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); containers must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
