Description

3-Hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid polymer with 1,6- diisocyanatohexane, diphenyl carbonate, 1,6-hexanediol, 5-isocyanato-1- (isocyanatomethyl)-1,3,3-trimethylcyclohexane and methyloxirane polymer with oxirane monobutyl ether, block is a specialized polyurethane-polycarbonate-polyether block copolymer designed for high-performance applications. This advanced polymer offers a unique balance of properties derived from its segmented structure, including toughness, flexibility, and hydrolytic stability. It is essential for formulators and manufacturers in industries requiring durable, customizable polymeric materials for coatings, adhesives, and elastomers.

Application

• High-Performance Coatings: Used as a key resin in automotive clear coats, industrial maintenance paints, and plastic coatings for exceptional durability, gloss, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a base polymer for structural adhesives, flexible sealants, and laminating agents, providing strong bonding with good elasticity.
• Specialty Elastomers: Formulated into castable or thermoplastic polyurethane (TPU) elastomers for gaskets, rollers, and impact-absorbing components.
• Medical Device Coatings: Potential use in biocompatible coatings for medical instruments and devices, leveraging its stability and film-forming capabilities.
• Fiber & Textile Finishes: Applied as a durable, flexible finish or sizing agent for technical textiles and synthetic fibers.
• Composite Materials: Acts as a matrix or toughening agent in polymer composites to enhance impact strength and interlayer adhesion.

Quality Control

Our production of this advanced block copolymer adheres to strict quality management systems. Each batch is characterized using advanced analytical techniques to ensure consistency in molecular weight, composition, and functional group content. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as solids content, viscosity, hydroxyl value, and isocyanate content (if applicable). We support compliance with relevant industry standards for raw materials.

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); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect product performance. Keep away from strong alkalis and incompatible organic solvents.
