TECHNICALTECHNICAL DATA BULLETIN SHEET TRIMET ® TME TRIMET ® TME in Short Oil Alkyd Resins Containing Phthalic Anhydride CH 2OH | CH 3 — C — CH 2OH | CH 2OH CAS Number: 77-85-0 TRIMET ® TME Trimethylolethane, manufactured by GEO Specialty Chemicals Inc., is a polyol useful in the preparation of alkyd resins. This bulletin contains a comparison of three polyols in a suggested starting formulation for both air-dry and baking enamels incorporating phthalic anhydride. TRIMET ® TME was evaluated against two alternative polyols: glycerol and Trimethylolpropane (TMP).

Quality coatings are proving attractive to many customers because better industrial finishes are necessary to meet the increasingly severe demand of many applications. Formulators who want to provide high-quality coatings find that alkyds containing TME afford the desired product improvements. Short oil alkyds vehicles are well accepted in industrial finishes as they are characterized by good drying properties, low cost and good solvent resistance. Short oil baking vehicles possess the additional benefits of excellent metal adhesion, good tolerance for over-bake, impact resistance and good flexibility. The air-dry data show the two resins to have a comparable viscosity, while the TME-based resin offers greater initial hardness. The TME-based resin also provides improved resistance to salt spray, stain, detergent, and water immersion when compared against the glycerol resin. The comparative baking data show the TME-based resin to have excellent flexibility, impact and adhesion characteristics. It also provides for improved resistance to stain, water immersion, humidity and salt spray.
