Pripol Dimerised Fatty Acid Unsaturated, natural oils and fats C=C C=O C=C-C-C=C C=O heat, pressure, catalyst C=O separation O=C HO C=O trimerised fatty acid O=C HO C=O dimerised fatty acid C=O isostearic fatty acid
General Features Pripol Dimer Acids Bio-based from natural fatty acids Large hydrocarbon part (C 36 ) hydrophobic hydrolytic resistance of derivatives affinity for non-polar matrices and surfaces O=C HO Irregular non-crystalline structure flexibility low Tg flow, wetting low modulus, no strain hardening no shrinkage C=O Di-functional constituent for: polyamides polyesters polyurethanes epoxies polyimides
Different Forms Dimer Technology Dimer acid Pripol Dimer diol Pripol HOOC HO CO Polyester polyols Priplast HO---- E--E ----- n Dimer diamine Priamine H 2 N NH 2
Priplast Technology Hydrocarbon nature Bio-based No ether linkage Stability against heat, oxygen and UV Hydrophobicity Hydrolytic stability Low moisture absorption Affinity for low polarity matrices and surfaces Non-crystalline structure Flexibility, low Tg No strain hardening Good flow and wetting Good adhesion to a wide range of substrates Hydroxyl functionality Reactivity in: polyurethanes, co-polyamides, co-polyesters etc. E--E n
