Waterborne vegetable oil epoxy coatings: Preparation and characterization

The utilization of renewable resources such as vegetable oils [VO] for the development of environment friendly waterborne [WB] materials is encouraged worldwide. The preparation of WB materials from VO is a challenging task due to their hydrophobic nature. The present work describes the synthesis of WB epoxy from VO [WBOE]. WBOE was characterized for its structural and physico-chemical attributes. The cured material was subjected to physico-mechanical, chemical resistance tests, and thermal analyses. The coatings of WBOE showed good physico-mechanical, chemical resistance as well as thermal stability and may find application as eco-friendly WB coatings with safe usage up to 220 °C.

► Waterborne epoxy coatings prepared from Linseed oil.
► Showed good coating performance.
► Can be safely employed up to 220 °C.
