Optimization of vanillin bis epoxy coating properties by changing resin composition and photocuring conditions
Original language description
Considering the current efforts for the development of new antimicrobial coatings from renewable resources suitable for application in environmentally friendly light-based technologies, the dependence of photocuring kinetics of vanillin bis epoxy resin and properties of the resulting coatings on the resin composition and process conditions was investigated. The photocuring rate, cross-linking density, and yield of the insoluble fraction, and thus the rheological, mechanical, and thermal properties of vanillin bis epoxy coatings have been found to be highly dependent on the amount of photoinitiator, solvent, and process temperature. The optimal resin, which ensures the highest thermal and mechanical characteristics of the coating, contained 3 wt% of a photoinitiator, triarylsulfonium hexafluorophosphate salts, and dichloromethane, and it was cured at 45 °C. Real-time photorheometry was shown to be able to be used for simple and quick determination of optimal resin composition and UV curing conditions to obtain coatings with desirable properties. The developed vanillin bis epoxy cross-linked coating is a viable alternative from renewable resources to petroleum-based epoxy analogues. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
