Description

1,2,3-Propanetriol, polymer with 2,4(or 4,6)-diethyl-6(or 2)-methyl-1,3-benzenediamine, 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, α-hydro-ω-hydroxypoly[ oxy(methyl-1,2-ethanediyl)], 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane is a specialized polyurethane prepolymer or resin intermediate, synthesized from a complex blend of polyols and isocyanates. This compound is engineered to deliver exceptional performance characteristics such as tailored flexibility, adhesion, and chemical resistance in advanced polymer systems. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop high-performance, durable end-products.

Application

• High-Performance Coatings: Used as a key resin component in protective and decorative coatings for automotive, industrial, and marine applications, offering enhanced durability and weather resistance.
• Advanced Adhesives & Sealants: Serves as a backbone polymer in formulating structural adhesives, potting compounds, and flexible sealants with strong bonding and elastic properties.
• Specialty Elastomers: Employed in the production of cast polyurethane elastomers for rollers, wheels, gaskets, and impact-absorbing components.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve interfacial adhesion and mechanical properties.
• Flexible Foams and Cushioning: Can be utilized in the formulation of tailored, high-resilience flexible polyurethane foams.
• Industrial Fabric Coatings: Applied in coatings for textiles, conveyor belts, and tarpaulins to impart waterproofing, abrasion resistance, and flexibility.

Quality Control

Our production of this polyurethane intermediate adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, solids content, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks for industrial chemicals.

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 containers tightly sealed to prevent moisture absorption, which can lead to premature reaction and gelation. Keep away from heat, sparks, and open flame.
