Description

Hexanedioic acid, polymer with 1,4-dihydroxy-2-butanesulfonic acid monosodium salt, 1,6-diisocyanatohexane, 1,6-hexanediol, 1,1'-methylenebis[4-isocyanatocyclohexane] and methyloxirane is a specialized polyurethane-polyether copolymer designed to deliver enhanced performance characteristics. This engineered polymer is significant for its ability to impart durability, flexibility, and ionic functionality to advanced material formulations. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty films and membranes.

Application

• High-Performance Coatings: Used as a key resin component in automotive, industrial, and marine coatings for superior weatherability, chemical resistance, and adhesion.
• Advanced Adhesives & Sealants: Serves as a base polymer for structural and flexible adhesives, offering excellent bonding strength and elasticity.
• Specialty Elastomers: Formulated into cast or thermoplastic polyurethane elastomers for gaskets, rollers, and impact-absorbing components.
• Functional Membranes: Utilized in the creation of ion-exchange or ultrafiltration membranes due to its sulfonate-containing, hydrophilic segments.
• Textile & Leather Finishes: Applied as a durable, flexible topcoat or binder for synthetic leather and technical textiles.
• Composite Materials: Acts as a matrix or toughening agent in fiber-reinforced composites for the aerospace and automotive sectors.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Every lot is characterized for critical parameters including molecular weight distribution, ionic content, viscosity, and residual monomers. A comprehensive Certificate of Analysis (COA) detailing all specification results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at a controlled room temperature (15-25°C). Ensure the original packaging is sealed after use to prevent moisture absorption, which can affect product performance. Store away from strong oxidizing agents and heat sources.
