Résumé : |
Ambadi oil (Hibiscus Cannabibus) obtained from the seeds of the plant, which is apparently indigenous to India. The seeds of this plant after milling and solvent extraction yielded 13% oil. The β-hydroxyalkyl amide of Ambadi oil has been synthesized by reaction between Ambadi oil and diethanol amine in presence of zinc oxide as a catalyst. The reaction is relatively rapid and proceeded to high yield at 200° ′ 5°C. The resulting β-hydroxyalkyl amide was used to formulate thermosetting coating compositions. Films were cured at ambient lair drying) and elevated (stove diving) temperatures using N, N-bis (2-hydroxyethyl) fatty amide (HAFA) of Ambadi oil as eco-friendly cross-linking agent for acrylic resin. The coating performance of the various compositions was tested by measurement of scratch hardness, impact strength and chemical resistance. The results show better performance of the HAFA based compositions compared to butylated melamine formaldehyde (MF) based compositions. |
