Breve introducción:
Epoxy Resin 127 is an unmodified, medium-to-low viscosity liquid epoxy resin synthesized from Bisphenol A and epichlorohydrin. Featuring a lower viscosity than standard Type 128 resin, it offers superior processing performance and can be cured with various curing agents at room or elevated temperatures to deliver exceptional mechanical, chemical, electrical, and adhesive properties.
