Description

Propanoic acid, 3-hydroxy-2-(hydroxymethyl)-2-methyl-, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, compd. with N,N-diet is a specialized, high-performance polymer with a complex polyurethane/polyurea architecture. This compound is engineered to deliver exceptional durability, chemical resistance, and adhesion properties, making it a critical component in advanced coating and adhesive formulations. It is primarily utilized by manufacturers in the industrial coatings, specialty adhesives, and advanced material sectors seeking to enhance product performance under demanding conditions.

Application

• High-Performance Industrial Coatings: Used as a key resin in formulations for heavy-duty protective coatings for metal, concrete, and composite substrates, offering excellent resistance to abrasion, chemicals, and weathering.
• Specialty Adhesives and Sealants: Serves as a primary component in structural and elastic adhesives requiring strong bonding, flexibility, and long-term durability in automotive, aerospace, and construction applications.
• Advanced Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composites to improve interlaminar adhesion, toughness, and environmental stability.
• Elastomer and Rubber Modification: Employed to enhance the properties of polyurethane elastomers, improving their tensile strength, tear resistance, and compatibility with other polymers.
• Corrosion-Resistant Linings: Formulated into tank linings, pipe coatings, and floor toppings for chemical processing plants due to its inherent resistance to strong acids and organic solvents.
• Automotive OEM and Refinish: Utilized in premium automotive clear coats, primer surfaces, and plastic part coatings that demand superior gloss retention and resistance to fuels and cleaners.

Quality Control

Every batch of our polymer is manufactured under strict quality management systems to ensure consistency and performance. We provide comprehensive Certificates of Analysis (COA) with key parameters such as NCO content, viscosity, solids content, and color. Our production adheres to relevant industry standards, and specifications can be aligned with customer-specific requirements for applications in coatings and adhesives.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. Due to its reactivity with strong acids and organic solvents, store separately from such materials. Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
