Description

Tdi/ Polypropylene Glycol/ 2-Hydroxyethyl Methacrylate CAS NO 9059-76-1 is a specialized urethane acrylate oligomer, a key reactive intermediate in advanced polymer synthesis. This compound is engineered to deliver enhanced cross-linking density and flexibility, making it a critical component for high-performance coatings and adhesives. It is primarily sought by formulators in the industrial coatings, UV-curable resins, and specialty sealants sectors who require materials that balance durability with processing versatility.

Application

• UV-Curable Coatings and Inks: Serves as a primary oligomer, providing excellent cure speed, adhesion, and chemical resistance for wood, plastic, and metal substrates.
• High-Performance Adhesives and Sealants: Imparts toughness and flexibility to structural adhesives, pressure-sensitive adhesives (PSAs), and elastic sealants.
• Industrial and Protective Coatings: Used in formulations for abrasion-resistant floor coatings, pipe coatings, and corrosion-resistant industrial finishes.
• Fiber Optic and Electronic Coatings: Employed in protective secondary coatings for optical fibers and conformal coatings for printed circuit boards (PCBs).
• 3D Printing Resins (SLA/DLP): Acts as a functional oligomer to enhance the mechanical properties and resolution of photopolymer resins.
• Overprint Varnishes and Release Coatings: Provides a durable, glossy finish for packaging and facilitates mold release in composite manufacturing.

Quality Control

Our Tdi/ Polypropylene Glycol/ 2-Hydroxyethyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as viscosity, acrylate equivalent weight, and residual monomer content. Certificates of Analysis (COA) documenting purity and full 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 / 59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
