Description

Phenol, 4,4-(1-Methylethylidene)Bis-, Polymer With (Chloromethyl)Oxirane, Monoesters With C18-Unsatd. Fatty Acid Dimers is a specialized epoxy resin derivative, modified with unsaturated fatty acid dimers to impart unique flexibility and hydrophobic properties. This advanced polymeric material is engineered to enhance the performance and durability of coatings and adhesives in demanding environments. It is a critical raw material for formulators in the protective coatings, marine paints, industrial adhesives, and composite materials industries seeking improved chemical resistance and weatherability.

Application

• As a flexibilizing and hydrophobic modifier in high-performance epoxy coating systems.
• Key component in marine and protective coatings for ships, offshore structures, and industrial equipment.
• Used in formulating industrial adhesives and sealants requiring enhanced moisture resistance.
• As a resin intermediate for composite materials in automotive and aerospace applications.
• In the production of electrical insulation varnishes and encapsulants.
• For modifying flooring and construction chemicals to improve durability and water repellency.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Quality parameters such as epoxy equivalent weight, acid value, viscosity, and color are strictly monitored. Certificates of Analysis (COA) are available upon request, and our manufacturing processes adhere to ISO 9001 quality management systems.

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 material is light-sensitive and should be stored away from direct light. It is also easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen blanket). Keep away from heat sources and incompatible materials.
