Description

Nco 700 is a high-purity isocyanate compound, specifically a key monomer and crosslinking agent used in advanced polymer synthesis. This product matters for its critical role in producing high-performance polyurethanes, coatings, and adhesives with superior durability and chemical resistance. Industries such as automotive manufacturing, construction, electronics encapsulation, and specialty elastomer production rely on its consistent reactivity and quality to ensure the integrity of their final materials.

Application

• Polyurethane Synthesis: A fundamental building block for producing flexible and rigid foams, elastomers, and coatings.
• Adhesive Formulation: Used in high-strength industrial and structural adhesives and sealants.
• Protective Coatings: Key component in abrasion-resistant, chemical-resistant, and weatherproof coating systems for industrial and marine applications.
• Elastomer Manufacturing: Essential for creating specialty cast elastomers and thermoplastic polyurethanes (TPU) with tailored properties.
• Composite Materials: Acts as a crosslinker in fiber-reinforced plastics and resin systems for the automotive and aerospace sectors.
• Electronic Encapsulation: Used in potting and encapsulation compounds to protect sensitive electronic components.

Quality Control

Our Nco 700 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including determination of NCO content, viscosity, color, and impurity profile. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee compliance with your technical 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); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture.
