Bissium neodecanoate is used as a catalyst to promote crosslinking reactions in solvent-free coatings. In systems such as polyurethane, epoxy resin and unsaturated polyester, bismuth neodecanoate can accelerate the reaction between isocyanate and polyol, epoxy groups and amine-based curing agents, thereby shortening the curing time and increasing the curing degree.

1.1 Catalytic action in polyurethane systems

In solvent-free polyurethane coatings, bismuth neodecanoate forms a carbamate bond by catalyzing the reaction between isocyanate groups (NCO) and hydroxyl groups (OH). This reaction is a critical step in the formation of polyurethane coatings. Studies have shown that bismuth neodecanoate can significantly increase the reaction rate, shorten the curing time, while maintaining the excellent mechanical properties and chemical resistance of the coating.

According to the study of Kumar et al. (2016), bismuth neodecanoate has better catalytic effect in solvent-free polyurethane coatings than traditional tin-based catalysts.
