Description

Polyurea CAS NO 37955-36-5 is a high-performance polymer formed by the reaction of an isocyanate component with an amine-terminated resin blend. This material is valued for its exceptional durability, fast curing times, and outstanding chemical and abrasion resistance. It is a critical component for industries requiring robust protective coatings and elastomeric linings. The product is hygroscopic (moisture-sensitive) and requires careful handling to maintain its performance integrity.

Application

• Protective Coatings: Used as a primary component in spray-applied, seamless protective linings for industrial flooring, secondary containment, and truck bed liners.
• Waterproofing Membranes: Employed in roofing systems, bridge decks, and parking structures due to its excellent waterproofing and weather-resistant properties.
• Pipeline and Tank Linings: Provides a corrosion-resistant barrier for oil & gas pipelines, chemical storage tanks, and wastewater treatment facilities.
• Marine and Offshore Coatings: Used to protect ship hulls, decks, and offshore structures from harsh marine environments and corrosion.
• Automotive and Transportation: Applied as a protective coating for vehicle underbodies, cargo areas, and industrial equipment subject to impact and wear.
• Infrastructure Rehabilitation: Utilized for the rapid repair and resurfacing of concrete structures, manholes, and tunnels.

Quality Control

Our Polyurea products are manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance. Key parameters such as viscosity, gel time, tensile strength, and elongation are rigorously tested. A Certificate of Analysis (COA) detailing specific test results is provided with each shipment to guarantee compliance with agreed specifications.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat, sparks, and open flame. Due to its hygroscopic nature, containers must be kept sealed when not in use to prevent moisture absorption, which can compromise product performance.
