Presentation Transcript
eo or po distribution
EO or PO Distribution
  • Alkoxylated products always have a Poisson distribution
  • Catalysis and/or reaction temperature can help control distribution
uniqema s process
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
features of bpa alkoxylates
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
benefits of using bpa alkoxylates
Benefits of Using BPA Alkoxylates
  • Corrosion resistance
  • Chemical and moisture resistance
  • Flexibility
  • Toughness/hardness
  • Improved adhesion
  • Tg variation to meet final product needs

effect of bpaa in metal coating polyester system
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
performance testing
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

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