Information @ a Glance

  • Polyetheramines are an extremely versatile product range. Mainly used to increase flexibility, toughness, hydrophilicity or hydrophobicity (depending on the product used), they also offer various reactivities, good temperature stabilities, are essentially colourless and have a low viscosity.
  • Advantages over other amine-based products JEFFAMINEŽ Polyetheramines offer lower toxicity, reduced tendency to discolour and as the amines can be hindered they can be less reactive.
  • Hindering the amines allows slower reactions e.g. with epoxy resins and better colour stability.
  • JEFFAMINEŽ Polyetheramines versatility comes from a wide range of molecular weights, amine functionality, repeating unit type and distribution.
  • The range, which is based on ethylene oxide  propylene oxide  an EO/PO mix and Polytetramethylene glycol (PTMEG), consists of Monoamines, Diamines, Tiamines, Secondary amines, Hindered amines and PTMEG-based amines.
  • The main advantages are Good low temperature properties, Flexibility, Toughness, Hydrophilicity/hydrophobicity (depending on the product used) Controlled moisture absorption.
  • Useful for a wide range of applications that include epoxy curing, polyurea and polyamides in a range of coatings, ink resins, adhesives, elastomers, hot melt adhesives, sealants, engineering plastics and composites.
  • Other applications include cement additives, oilfield (demulsification) and acid neutralisation.
  • Hyperbranched poly(ether amine)s (hPEAs) with different ratios between poly(propylene oxide) (PPO) and poly(ethylene oxide) (PEO) were synthesized according to the previous report.
  • Different water-soluble dyes Rhodamine 6G (R6G), Rose Bengal Na Salt (RB), Neutral Red (NR), Methylene Blue trihydrate (MB), Methyl Orange (MO), Bismarck brown Y (BY), Ponceau S (PS) and Calcein (Cal) used in this study were purchased from Sinopharm Chemical.
  • Often, the primary amine functionality of conventional (DMC catalyzed) polyetheramines is low due to incomplete amination (approximately 85% conversion efficiency).
