Description

1,3-Pentanediol, 2,2,4-trimethyl-, polymer with 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and α-hydro-ω-hydroxypoly[ oxy(methyl-1,2-ethanediyl)] is a high-performance polyurethane prepolymer or resin intermediate, identified by CAS NO 105431-78-5. This specialized polymer is engineered to provide exceptional durability, flexibility, and chemical resistance in demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Coatings: Used as a key binder in industrial and protective coatings for metal, concrete, and plastics, offering excellent weatherability and corrosion resistance.
• Advanced Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives, flexible sealants, and potting compounds with strong bonding and elastic properties.
• Elastomer Production: Acts as a prepolymer in the manufacture of castable polyurethane elastomers for wheels, rollers, and industrial parts requiring abrasion resistance.
• Composite Materials: Utilized as a matrix resin or modifier in fiber-reinforced composites to improve toughness and interlaminate adhesion.
• Specialty Inks: Incorporated into formulations for flexible packaging and textile inks to enhance adhesion and durability.
• Waterborne Dispersions: Can be formulated into aqueous polyurethane dispersions (PUDs) for environmentally friendly coating and adhesive applications.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical formulation parameters. Quality is verified through testing of key parameters such as NCO content, viscosity, solids content, and color. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance protocols.

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 / 59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture ingress, which can lead to premature reaction and gelation. Keep away from heat sources and open flames.
