High purity (>99.0% minimum) with low volatility and excellent thermal stability.
Low water content (<0.10%) ensuring superior hydrolytic resistance in resin systems.
Consistent crystalline structure and narrow melting point range (127–130 °C), enabling reliable processing.
Exceptional resistance to oxidation and discoloration under UV exposure and elevated temperatures.
Low acidity (acid number ≤0.5 mg KOH/g) minimizes catalytic side reactions during polyester and alkyd synthesis.
High-performance polyester resins for coil coatings and automotive topcoats.
Crosslinking agent in powder coatings requiring excellent flow, gloss retention, and weatherability.
Key monomer in alkyd resins for industrial maintenance and marine coatings.
Building block for synthetic lubricants and plasticizers with enhanced thermal and oxidative stability.
Raw material in specialty polyacrylates and UV-curable resins for electronics encapsulation.
