Description

Fatty acids, tall-oil, esters with diethylene glycol, polymers with 1,4-benzenedicarboxylic acid manuf. byproduct esters with diethylene glycol, polymethylenepolyphenylene isocyanate and triethanolamine CAS NO 141785-68-4 is a specialized polymeric resin designed for high-performance applications. This compound is valued for its unique combination of properties derived from tall oil fatty acids, aromatic dicarboxylic acid structures, and polyurethane-forming components. It is primarily utilized in industrial sectors requiring durable, chemically resistant, and versatile polymeric materials. Key industries include coatings, adhesives, sealants, and elastomers (CASE) manufacturing.

Application

• Industrial Coatings and Paints: As a resin component for high-durability, chemical-resistant, and flexible protective coatings for metal, wood, and concrete.
• Adhesives and Sealants: Serving as a key polymeric backbone in formulations requiring strong bonding, flexibility, and resistance to environmental stress.
• Elastomers and Rubber Modifiers: Used to enhance the flexibility, tensile strength, and aging properties of polyurethane and other synthetic rubbers.
• Composite Materials: As a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve impact resistance and adhesion.
• Printing Inks: Imparting specific rheological and film-forming properties to specialty ink formulations for packaging and industrial printing.
• Foundry and Molding Sands: Acting as a binder resin in cold-box or no-bake foundry processes for core and mold making.

Quality Control

Our production of this specialty polymeric resin adheres to stringent quality control protocols to ensure batch-to-batch consistency and performance reliability. Quality is monitored through parameters including viscosity, acid value, hydroxyl value, isocyanate content (NCO%), and color. Certificates of Analysis (COA) detailing these specifications are provided with each shipment. Our manufacturing processes are designed to meet the demanding requirements of industrial polymer applications.

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 to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
