Abstract
ABSTRACTAmid the urgent call for the coatings industry to increase ecological awareness, a decisive shift toward environmentally friendly coatings is imperative. In this study, the L9(34) orthogonal experimental design is used to optimize the formula of the waterborne coating made from waterborne saturated (WS) polyester resins and totally methyl etherified amino resins. The composite resin coatings exhibit excellent properties under optimized conditions (resin solid content ratio 2:1, curing time 40 min, curing temperature 433 K). FTIR confirms the successful crosslinking between WS polyester and totally methyl etherified amino resin, and TGA shows four‐stage thermal weight loss, with the most significant loss in the third stage (623–743 K). Pyrolysis kinetics at this stage, analyzed using Kissinger‐Akahira‐Sunose and Coats‐Redfern method methods, reveal a three‐dimensional diffusion mechanism with an activation energy of 215.25 kJ/mol and a pre‐exponential factor of 6.83 × 1015 min−1. This research enhances understanding and advancement of sustainable coating technologies for various industrial applications.
