Description

Hexanedioic acid, polymer with 1,6-hexanediol, 1,3-isobenzofurandione, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane and 1,2,3-propanetriol, 2-hydroxyethyl acrylate-blocked is a specialized, multi-component polymeric material designed for high-performance applications. This compound matters as a versatile building block for creating durable, cross-linked networks with excellent chemical and thermal resistance. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Industrial Coatings: Used as a cross-linking agent in polyurethane and polyester-based coatings for automotive, aerospace, and marine applications, providing excellent weatherability and chemical resistance.
• Advanced Adhesives and Sealants: Serves as a key component in formulating structural adhesives and elastic sealants with strong bonding strength and long-term durability.
• Specialty Elastomers: Employed in the synthesis of polyurethane elastomers for gaskets, rollers, and industrial parts requiring a balance of flexibility and toughness.
• UV-Curable Resin Systems: The acrylate-blocked isocyanate functionality allows for its use in radiation-curable coatings and inks, enabling fast curing and low VOC formulations.
• Powder Coatings: Acts as a cross-linker in thermosetting powder coatings, contributing to smooth finishes and excellent mechanical properties for appliances and metal furniture.
• Composite Materials: Utilized as a matrix resin or modifier in fiber-reinforced plastics (FRP) to improve interlaminar shear strength and thermal stability.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Every batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of NCO content, viscosity, solids content, and blocking agent efficiency. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance specifications is provided with each shipment to guarantee it meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive) and must be protected from atmospheric moisture to prevent premature reaction and viscosity increase. Keep away from heat sources and open flames.
