Description

1,3-Propanediol, 2,2-Bis(Hydroxymethyl)-, Polymer With 1,3-Bis(1-Isocyanato-1-Methylethyl)Benzene, 2-Propenoate is a specialized, high-performance polymer derived from a polyol and an aromatic diisocyanate, subsequently functionalized with an acrylate group. This unique chemical architecture provides a versatile platform for creating durable, cross-linked networks with excellent chemical and mechanical resistance. It is a critical raw material for formulators and manufacturers in advanced coatings, adhesives, and composite materials seeking to enhance product performance and longevity.

Application

• High-Performance Coatings: Used as a key resin component in UV-curable industrial, wood, and metal coatings, providing excellent hardness, gloss, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a backbone polymer in structural adhesives and sealants, offering strong bonding strength and durability under harsh environmental conditions.
• Composite Materials: Acts as a matrix resin or cross-linking agent in fiber-reinforced plastics (FRP) and other composite systems to improve mechanical properties.
• Industrial Inks: Formulated into UV-curable inks for printing on plastics, metals, and other substrates requiring fast curing and robust performance.
• 3D Printing Resins: Utilized in stereolithography (SLA) and other photopolymerization-based additive manufacturing processes to create precise, high-strength parts.
• Optical Materials: Potential use in the formulation of clear, durable lenses, optical films, and encapsulants due to its ability to form transparent, stable polymers.

Quality Control

Our production of this urethane acrylate oligomer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, acrylate equivalent weight, and residual isocyanate content are rigorously monitored. Certificates of Analysis (COA) detailing purity, functional group content, and physical specifications are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen blanket) after opening to prevent polymerization and maintain stability. Keep away from heat sources and incompatible materials.
