Description

1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with 1,3-diisocyanatomethylbenzene, .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 2,2'-oxybis[ethanol] is a high-performance, multi-component polyurethane prepolymer or resin intermediate. This specialized chemical offers versatile reactivity and tunable properties, making it a critical raw material for formulating advanced polymeric systems. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing specialty composites and functional materials.

Application

• High-Performance Coatings: Used as a key resin component in polyurethane-based industrial, automotive, and protective coatings for enhanced durability, chemical resistance, and flexibility.
• Adhesives & Sealants: Serves as a prepolymer in the formulation of structural adhesives, potting compounds, and elastic sealants with strong bonding and weather-resistant properties.
• Elastomer Production: Acts as a building block for manufacturing castable, thermoplastic, or millable polyurethane elastomers used in wheels, rollers, and gaskets.
• Composite Materials: Employed in the production of fiber-reinforced plastics (FRP) and composite matrices, contributing to improved mechanical strength and interfacial adhesion.
• Specialty Resins: Utilized in the synthesis of tailored resins for electronic encapsulation, 3D printing materials, and other advanced polymer applications.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters such as NCO content, hydroxyl value, viscosity, and solids content are strictly monitored. Certificates of Analysis (COA) are available upon request, detailing the specifications for each production lot.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is moisture-sensitive; keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect reactivity and properties.
