Description

2,2'-[1,4-Phenylenebis(Oxy) Bis-Ethanol, Polymer With 1,1'-Methylenebis[4-iso-Cyanatobenzene], Oxirane And Tetrahydro-Furan is a specialized polyurethane-polyether hybrid polymer. This advanced material is engineered to deliver a unique balance of chemical resistance, flexibility, and durability, making it a critical component in high-performance formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for demanding applications.

Application

• High-Performance Coatings: Used as a key resin in industrial, automotive, and marine coatings requiring excellent weatherability, chemical resistance, and mechanical strength.
• Advanced Adhesives & Sealants: Serves as a base polymer for structural adhesives, potting compounds, and flexible sealants where strong bonding and environmental stability are paramount.
• Specialty Elastomers: Formulated into castable polyurethane elastomers for rollers, gaskets, and wear-resistant parts.
• Composite Materials: Acts as a matrix or modifier in fiber-reinforced composites to enhance toughness and interfacial adhesion.
• Electronic Encapsulation: Employed in potting and encapsulation compounds to protect sensitive electronic components from moisture, vibration, and thermal shock.
• Industrial Fabric Coatings: Used to coat technical textiles, conveyor belts, and industrial fabrics to impart durability, flexibility, and resistance to oils and solvents.

Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, hydroxyl value, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture which can affect product performance.
