Description

p-tert-Butylphenol, Nonylphenol, Dinonylphenol, Formaldehyde, Oxirane Polymer is a specialized phenolic resin intermediate, synthesized from key phenolic compounds and formaldehyde, capped with an oxirane (epoxy) functional group. This engineered polymer is crucial for providing enhanced thermal stability, chemical resistance, and superior adhesion properties in high-performance coating and adhesive formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composite materials and electronic encapsulants.

Application

• Epoxy Resin Modifier: Acts as a reactive diluent and flexibilizer to improve toughness and processability of epoxy systems.
• High-Performance Coatings: Used in formulating industrial, marine, and automotive coatings for excellent corrosion and chemical resistance.
• Structural Adhesives: A key component in adhesives for aerospace, automotive, and construction, offering strong bonding under stress.
• Electrical Laminates & Encapsulants: Imparts good electrical insulation and thermal properties in composites for PCBs and electronic components.
• Fiber-Reinforced Composites: Serves as a matrix resin modifier to enhance interlaminar shear strength and durability.
• Foundry Resins: Used in cold-box and no-bake binder systems for sand casting in metalworking.

Quality Control

Our p-tert-Butylphenol, Nonylphenol, Dinonylphenol, Formaldehyde, Oxirane Polymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as epoxy equivalent weight (EEW), viscosity, and hydroxyl value. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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. Containers should be kept tightly sealed when not in use to prevent moisture absorption and maintain product integrity.
