Description

1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-, Polymer With 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane is a high-performance polyol-based polymer, specifically a polyurethane polyol, derived from the reaction of trimethylolpropane (TMP) and isophorone diisocyanate (IPDI). This specialized polymer is valued for its excellent weatherability, chemical resistance, and mechanical properties, making it a critical component in demanding industrial formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for producing high-end, durable products.

Application

• High-Performance Coatings: A key resin component in automotive OEM and refinish coatings, industrial maintenance paints, and marine coatings where superior gloss retention, UV resistance, and hardness are required.
• Advanced Adhesives & Sealants: Used in formulating structural adhesives for aerospace, automotive, and construction applications, as well as high-strength, flexible sealants.
• Elastomers and Castable Urethanes: Serves as a polyol for manufacturing tough, abrasion-resistant polyurethane elastomers used in rollers, wheels, and industrial parts.
• UV-Curable Systems: Can be functionalized for use in radiation-curable coatings and inks, offering fast cure times and enhanced performance.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve interfacial adhesion and durability.
• Industrial Flooring and Linings: A vital ingredient in chemical-resistant and heavy-duty floor coatings and tank linings for the chemical processing industry.

Quality Control

Our production of this polyurethane polyol adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value (OHV), viscosity, isocyanate (NCO) content, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every 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 a recommended temperature of 15-25°C. This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and open flame.
