Description

Hexanedioic acid, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, Me Et ketone oxime-blocked is a specialized blocked polyisocyanate crosslinker, a key component in high-performance coating systems. Its blocked isocyanate functionality provides excellent shelf stability and controlled reactivity, enabling the formulation of one-component (1K) polyurethane coatings that cure upon heating. This product is essential for manufacturers seeking durable, chemical-resistant finishes with superior mechanical properties for demanding industrial applications.

Application

• One-Component (1K) Polyurethane Coatings: Serves as a latent crosslinker that activates during thermal curing, providing excellent film hardness, chemical resistance, and weatherability.
• Automotive OEM and Refinish Coatings: Used in clearcoats and pigmented topcoats requiring high gloss retention, scratch resistance, and durability against fuels and solvents.
• Industrial Metal Coatings: Formulated into primers and topcoats for agricultural, construction, and heavy equipment, offering superior corrosion protection and impact resistance.
• Coil and Can Coatings: Provides the crosslinking for flexible, formable coatings on metal substrates used in appliances, building panels, and food/beverage containers.
• Plastic Coatings: Enhances adhesion and provides a hard, mar-resistant finish on automotive interior trim, consumer electronics, and other plastic components.
• High-Performance Wood Finishes: Used in factory-applied finishes for furniture, flooring, and cabinetry that require extreme durability and resistance to household chemicals.
• Adhesives and Sealants: Imparts enhanced strength, flexibility, and environmental resistance in formulated adhesive systems for specialized bonding applications.

Quality Control

Our production of this blocked polyisocyanate crosslinker adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as blocked isocyanate content, viscosity, solids content, and color are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and formulation processes.

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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture ingress, which can lead to premature reaction and gelation. Keep away from heat, sparks, and open flame.
