Description

2-Propenoic Acid,2-Hydroxyethyl Ester,Polymer With 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane CAS NO 88177-19-9 is a specialized polyurethane-acrylate hybrid polymer, synthesized from 2-hydroxyethyl acrylate and isophorone diisocyanate (IPDI). This compound is engineered to deliver a unique combination of high-performance durability and excellent weatherability, making it a critical component in advanced coating systems. It is primarily sought by formulators in the industrial coatings, adhesives, and advanced materials sectors who require enhanced mechanical properties and chemical resistance in their final products.

Application

• High-Performance Industrial Coatings: Used as a key resin in formulations for automotive topcoats, coil coatings, and heavy-duty machinery finishes, providing excellent gloss retention and resistance to abrasion, chemicals, and UV degradation.
• Advanced Wood & Furniture Coatings: Imparts superior scratch resistance, clarity, and fast curing properties to premium wood lacquers and furniture varnishes.
• Specialty Adhesives & Sealants: Serves as a toughening agent or primary binder in structural adhesives and high-strength sealants, enhancing flexibility and bond strength under varying environmental conditions.
• UV-Curable Coating Systems: Acts as a reactive oligomer in UV-curable inks and coatings for plastics and metals, enabling rapid curing and a hard, durable surface finish.
• Optical Fiber Coatings: Utilized in protective secondary coatings for optical fibers due to its balance of flexibility, adhesion, and low moisture absorption.
• 3D Printing Resins: Incorporated as a performance modifier in photopolymer resins for stereolithography (SLA) and digital light processing (DLP) 3D printing to improve part toughness and thermal stability.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including monomer conversion, molecular weight distribution, viscosity, and residual isocyanate content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. Our quality commitment supports compliance with relevant global regulatory frameworks for industrial chemicals.

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 moisture-sensitive; keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and open flame.
