Description

Hexanedioic acid, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, 1,4-butanediol, 1,6-hexanediol, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, 4,4'-(1-methylethylidene)bis[phenol] and methyloxirane, 2-ethyl-1-hexanol-blocked is a specialized, blocked polyurethane prepolymer or resin intermediate. This high-performance material is engineered to provide controlled reactivity and enhanced shelf stability for demanding industrial formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries who require precise processing and superior final product properties such as durability, chemical resistance, and flexibility.

Application

• High-Performance Coatings: Used as a key resin component in automotive, industrial, and protective coatings requiring excellent weatherability, gloss retention, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a base polymer for structural adhesives, potting compounds, and elastic sealants where strong bonding and flexibility are critical.
• Elastomer Production: Employed in the manufacture of castable polyurethane elastomers for rollers, wheels, gaskets, and other mechanical parts demanding toughness and abrasion resistance.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites for the automotive, aerospace, and marine sectors.
• Industrial Binders: Utilized in formulating binders for specialty textiles, non-wovens, and filtration media.
• Encapsulation Resins: Suitable for electronic encapsulation and insulation applications due to its tailored polymer properties.

Quality Control

Every batch of our blocked polyurethane prepolymer is manufactured under a strict quality management system. We perform rigorous in-process and final testing to ensure consistent performance, including analysis of key parameters such as blocking agent content, viscosity, solids content, and color. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee compliance with 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). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
