Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : The main by-product from palm oil refining is palm fatty acid distillate (PFAD). It mainly consists of palmitic acid, oleic acid and to a lesser extent of their glycerides. PFAD can serve as an inexpensive bio-sourced raw mateial for the synthesis of hydrophobic acrylic resins. It is usually used in the manufacture of cheap soaps, as a precursor for animal feed and as a raw material for oleo-chemistry.

Procédés de fabricationIndex. décimale : 667.9 Revêtements et enduits Résumé : The use of artificial intelligence is currently finding its way into various industries and specialist disciplines. With the help of machine learning (ML), the experimental design, formulation, and testing of chemicals can made significantly more efficient in both time and resource efficiency. On possible application is to create a desired color code using different pigment pastes while producing the smallest possible number of samples. With a smaller number of tests, the new method presented leads to a more accurate prediction when compared to a classic experimental design plan.
