Description

Propanoic acid, 3-hydroxy-2-(hydroxymethyl)-2-methyl-, polymer with 1,3-bis(1-isocyanato-1-methylethyl)benzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) and 2-methyl-1,5-pentanediamine, compd. with N is a specialized polyurethane prepolymer or resin intermediate, identified by CAS 247108-87-8. This engineered polymer is valued for its ability to impart enhanced toughness, flexibility, and chemical resistance to final formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop high-performance products.

Application

• High-Performance Coatings: Used as a binder or crosslinker in industrial, automotive, and protective coatings requiring durability and weatherability.
• Adhesives & Sealants: Serves as a key component in formulating structural adhesives, laminating adhesives, and flexible sealants with strong bonding properties.
• Elastomers and Castable Urethanes: Employed in the production of polyurethane elastomers for rollers, wheels, gaskets, and other molded parts.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics and other composite systems.
• Textile & Leather Finishing: Utilized in coatings and finishes to provide water resistance, abrasion resistance, and a soft hand feel.
• Specialty Resins: Incorporated into formulations for potting compounds, encapsulants, and other electronic materials.

Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, and hydroxyl value are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., nitrogen blanket) to prevent premature reaction and gelation. Recommended storage temperature is between 15°C and 25°C in a cool, dry, well-ventilated area away from heat sources and incompatible materials.
