Description

Ethanol, 2,2'-thiobis-, polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl) ether with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol (3:1) and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, 2-hydroxyethyl acrylate-blocked is a specialized, high-performance blocked polyisocyanate prepolymer. This advanced material serves as a key cross-linking agent in formulations requiring controlled reactivity and enhanced final film properties. It is essential for manufacturers in the coatings, adhesives, and advanced polymer industries seeking to develop products with superior durability, chemical resistance, and application flexibility.

Application

• High-Performance Industrial Coatings: Used as a cross-linker in polyurethane-based coatings for automotive, aerospace, and heavy-duty machinery, providing excellent hardness, gloss, and weather resistance.
• Advanced Adhesives and Sealants: Acts as a curing agent in moisture-cure and heat-activated adhesive systems, offering strong bonding and flexibility.
• UV-Curable Coating Formulations: Incorporated as a reactive diluent or cross-linking component in systems where the blocked isocyanate group is activated upon exposure to UV light and heat.
• Elastomer and Rubber Modification: Enhances the mechanical properties, abrasion resistance, and thermal stability of specialty polyurethane elastomers.
• Fiber and Textile Finishes: Utilized in coatings for synthetic fibers and technical textiles to improve water repellency, durability, and handle.
• Wood and Plastic Coatings: Provides a durable, clear finish for furniture, flooring, and plastic substrates with enhanced resistance to solvents and scratches.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of NCO content, blocking agent ratio, viscosity, and color. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment to guarantee traceability and compliance with your formulation requirements.

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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent exposure to atmospheric moisture, which can lead to premature reaction and gelation.
