Polyester resin has largely supplanted mother-of-pearl in button production due to its ease of reproducibility in series, leading to significant cost reductions. Resin production is easily reproducible in series, resulting in a significant improvement in production costs.
Polyester resin for buttons is characterized by its ease of pigmentation with both natural and synthetic systems, as well as the ability to achieve excellent hardness after proper catalysis. Carlo Riccò & F.lli has also developed a polyester resin perfect for transparent buttons, appreciated for its final color after curing.
