Description

1,3,5-Triazine-2,4,6(1H,3H,5H)-trione, 1,3,5-tris(2-hydroxyethyl)-, polymer with 2,2-dimethyl-1,3-propanediol, 1,2-ethanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and hexahydro-1,3-isobenzofurandione is a high-performance, cross-linked polyester-polyurethane polymer derived from isocyanurate and phthalic anhydride chemistry. This specialized material is engineered to provide exceptional durability, chemical resistance, and thermal stability for demanding industrial applications. It is a critical component for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials.

Application

• High-Performance Industrial Coatings: Used as a resin in premium polyurethane coatings for metal, concrete, and plastic substrates, offering superior weatherability, abrasion resistance, and chemical protection.
• Adhesives and Sealants: Serves as a key polymeric backbone in structural adhesives and flexible sealants, providing strong bonding and long-term elasticity.
• Elastomers and Castable Urethanes: A fundamental raw material for manufacturing polyurethane elastomers with excellent mechanical properties, used in rollers, wheels, and industrial parts.
• Composite Materials: Acts as a matrix resin in fiber-reinforced composites for automotive, aerospace, and marine applications, enhancing strength-to-weight ratios.
• Electrical Encapsulation: Employed in potting and encapsulation compounds to protect sensitive electronic components from moisture, vibration, and thermal cycling.
• Specialty Inks and Pigment Dispersions: Functions as a grinding resin or binder in high-quality printing inks and pigment preparations.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including hydroxyl value, acid value, viscosity, and color to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks for industrial chemicals.

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). Keep away from heat sources and open flames. This material is moisture-sensitive (hygroscopic); ensure containers are sealed after use to prevent absorption of atmospheric moisture, which can affect product performance.
