Description

2-Propenoic Acid, 2-Hydroxyethyl Ester, Polymer With 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane And Methyloxirane is a specialized, high-performance polymer derived from hydroxyethyl acrylate, isophorone diisocyanate (IPDI), and propylene oxide. This compound matters for its unique combination of acrylic functionality and polyurethane/polyether backbone, offering exceptional adhesion, flexibility, and chemical resistance. It is primarily needed by formulators in the coatings, adhesives, and advanced materials industries seeking to enhance product durability and performance under demanding conditions.

Application

• High-Performance Coatings: Used as a key resin in industrial, automotive, and marine coatings for superior weatherability, gloss retention, and corrosion resistance.
• Advanced Adhesives & Sealants: Serves as a toughening agent or primary binder in structural adhesives, pressure-sensitive adhesives (PSAs), and elastic sealants.
• UV-Curable Systems: Acts as a reactive oligomer or prepolymer in UV-curable inks, coatings, and 3D printing resins due to its acrylate end-groups.
• Elastomers and Impact Modifiers: Incorporated into polyurethane elastomers and thermoplastic blends to improve impact strength, flexibility, and low-temperature performance.
• Fiber Optic and Electronic Coatings: Utilized in protective coatings for optical fibers and electronic components, leveraging its good adhesion and insulating properties.
• Composite Materials: Functions as a matrix resin or interfacial modifier in fiber-reinforced composites for aerospace and automotive applications.

Quality Control

Our production of this advanced polymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, hydroxyl value, isocyanate content (NCO%), and acrylate functionality are strictly monitored. Certificates of Analysis (COA) detailing specific grade specifications are available upon request, supporting compliance with relevant industry standards for raw materials.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and open flame.
