Description

Caprolactone-Tdi-Trimethylolpropane Methylated Copolymer is a specialized polyol-based polymer, synthesized from caprolactone, toluene diisocyanate (TDI), and trimethylolpropane. This engineered copolymer is valued for its excellent flexibility, hydrolytic stability, and compatibility with various resin systems, making it a crucial performance modifier. It is primarily sought by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in polyurethane production, to enhance product durability and processing characteristics.

Application

• As a flexibilizing agent and impact modifier in high-performance polyurethane coatings and adhesives.
• Key component in the formulation of elastomers and sealants requiring superior weatherability and moisture resistance.
• Modifier for acrylic and polyester resin systems to improve film flexibility and adhesion to diverse substrates.
• Used in the production of specialty inks and overprint varnishes to achieve desired rheological and film properties.
• Intermediate in the synthesis of urethane prepolymers for foam and composite applications.
• As a reactive diluent or crosslinker in radiation-curable coating formulations.

Quality Control

Our Caprolactone-Tdi-Trimethylolpropane Methylated Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including verification of hydroxyl value, viscosity, and acid number. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. As with most polymeric materials, prolonged exposure to high humidity should be avoided to prevent moisture absorption.
