Huile de son de rizTags : 'Rice bran oil (RBO)' ' Maleic anhydride (M.A)' N 'N-Bis (2-hydroxy ethyl) fatty amide (HEFA)' Index. décimale : 667.9 Revêtements et enduits Résumé : Rice bran oil (RBO) was malenized at 210°C using three different mole ratios of oil and maleic anhydride till desirable acid value of resultant product was achieved. The malenized products were neutralized with triethylamine to make them water compatible. N, N-Bis (2-hydroxy ethyl) fatty amide (HEFA) was prepared by reacting RBO with diethanolamine in the presence of zinc oxide as catalyst. The water compatible malenized products were blended with N, N-Bis (2-hydroxy ethyl) fatty amide (HEFA) in different ratios to prepare water based stoving compositions. Certain compositions were found to have comparable performance to that of the conventional water based alkyd-HEFA compositions when they were tested for their film and other properties. Note de contenu : - Water thinable vegetable oils
- Material and methods: Materials - Preparation of HEFA - Malenization of RBO - Neutralization of malenized oil with triethyl amine - Preparation of stoving agents - Characterization of coatings
- Result and discussion: - Mechanical properties - Chemical resistance - Solvent and water resistance - IR Spectrum

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

The polyamide resins were characterized for physico-chemical characteristics. Coating compositions based on epoxy resin and polyamide resins were made and evaluated for film and other properties Certain compositions were found to have satisfactory performance when compared with that of compositions based on epoxy resin and polyamide resins made from commercial dimer fatty acids.
