  1. Bis-Phenol A Alkoxylates

  2. BPA Propoxylate

  3. BPA Ethoxylate

  4. EO or PO Distribution • Alkoxylated products always have a Poisson distribution • Catalysis and/or reaction temperature can help control distribution

  5. Uniqema’s Process • Sophisticated post-treatment technique • Low acid number • Gardner color consistently at 1 or below • Very low ion content (Na/K/P) • Tight distribution

  6. Features of BPA Alkoxylates • Hydroxyl termination for use as a resin or a resin intermediate • Aromatic moiety for resistance, adhesion and toughness • Free rotation of methyl groups between aromatic groups for flexibility • Limitless variations in size of EO, PO or EO/PO chains

  7. Benefits of Using BPA Alkoxylates • Corrosion resistance • Chemical and moisture resistance • Flexibility • Toughness/hardness • Improved adhesion • Tg variation to meet final product needs

  18. Current Uses • Unsaturated polyester resins for fiberglass reinforcement, glass sizing and corrosion resistance • Use PO derivatives from 2.0 to 16.0 • Provide moisture and chemical resistance, adhesion, corrosion resistance • Toner resins • Use EO and PO derivatives 2.0 - 2.2 • Control of Tg (glass transition temperature)

  19. Current Uses • Electodeposition coatings • Use 6.0 EO derivative • Provides hardness for stone resistance and adhesion • Radiation curable monomers • Use EO derivatives from 2.2 to 30 moles • Provide resistances, hardness/flexibility and adhesion

  20. Current Uses • Urethane foam and adhesives • Use various EO and PO derivatives • Provide adhesion to metal

  21. Effect of BPAA in metal coating polyester system • Polyester melamine system • solvent based • building blocks used • Neopentylglycol, Hexanediol, Adipic acid, Isophtalic acid, Terephtalic acid • Hexanediol and Neopentylglycol were used as reference and partially replaced with BPAA

  22. Performance testing • Hardness • König Hardness represents the visco-elastic behaviour of a coating • Buchholz Hardness represents deformation elasticity, i.e. a kind of recoverability (nail test), required for metal coating in particular • Some applications require both properties

  26. Melamine curing • Polyester / melamine ratio: 15 / 1 • Pigment / binder ratio: 12 / 11 • The coating was applied and cured for 1 minute at 230ºC

  27. BPAAUniqema’s business focus • Commitment to & focus on the polymer market • Dedicated Polymer SBU • dedicated sales & marketing, TSS & application people • Polymer di-functional building block experience • Resin synthesis capability • e.g. polyester • Developing application data & knowledge • polyester metal coatings • Plants in more than one region • Europe and USA • Potential to tailor make EO and PO products in both regions
