Features Of GEO TME Trimethylolethane

  1. High-purity triol with exceptional hydroxyl functionality (3 OH groups per molecule) for robust crosslinking efficiency.

  2. Low volatility and excellent thermal stability, enabling safe handling and processing in high-temperature resin systems.

  3. Superior solubility in common organic solvents and compatibility with polyester, alkyd, and acrylic resins.

  4. Consistent batch-to-batch quality supported by rigorous QC testing and ISO 9001-certified manufacturing.

  5. Non-corrosive and low water content (<0.1%), minimizing side reactions during polycondensation or curing.

Typical Applications Of GEO TME Trimethylolethane

  1. Primary crosslinker in high-performance powder coatings for automotive and appliance finishes.

  2. Key monomer in UV-curable inks and coatings requiring rapid cure response and enhanced hardness.

  3. Building block for synthetic lubricants and high-viscosity ester-based functional fluids.

  4. Co-monomer in alkyd resins to improve gloss retention, flexibility, and chemical resistance.

  5. Intermediate in the synthesis of specialty plasticizers for PVC and thermoplastic elastomers.
