Description

Tdi/ Propylene Oxide/ 2-Hydroxyethyl Acrylate Polymer CAS NO 70801-06-8 is a specialized urethane-acrylate hybrid polymer, synthesized from toluene diisocyanate (TDI), propylene oxide, and 2-hydroxyethyl acrylate. This engineered material combines the toughness and chemical resistance of polyurethanes with the excellent UV curability and adhesion properties of acrylics. It is a critical raw material for formulators seeking to develop high-performance, durable coatings, adhesives, and sealants with enhanced processing flexibility.

Application

• UV-Curable Coatings: A key oligomer for wood, plastic, and metal coatings requiring fast cure times, high gloss, and superior scratch resistance.
• Industrial Adhesives & Sealants: Used to formulate high-strength, flexible adhesives for automotive, construction, and composite bonding applications.
• Overprint Varnishes: Provides durable, glossy, and protective finishes for packaging and printed materials.
• 3D Printing Resins: Serves as a reactive component in stereolithography (SLA) and digital light processing (DLP) resins for producing tough, functional prototypes and parts.
• Electronic Encapsulants: Formulated into potting compounds and conformal coatings that protect circuitry from moisture, chemicals, and mechanical stress.
• Fiber Optic Coatings: Used in primary and secondary coatings to protect glass fibers while maintaining signal integrity and flexibility.

Quality Control

Our Tdi/ Propylene Oxide/ 2-Hydroxyethyl Acrylate Polymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in viscosity, acrylate equivalent weight, and residual monomer content. Certificates of Analysis (COA) documenting key specifications are available upon request 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 room temperature (15-25°C). Keep away from heat sources and open flame. To prevent premature polymerization, storage under an inert atmosphere (e.g., nitrogen) is recommended for long-term stability.
