Using unsaturated resin to make glass fiber reinforced plastic products, without adding accelerant, only curing agent, can I? What is the function of accelerant?
The curing reaction of unsaturated polyester resin is free radical polymerization, and its curing agent is actually an initiator, usually organic peroxide.
Its promoter is cobalt water (cobalt cobalt cobalt solution), its role is to promote the curing reaction (to speed up the reaction). Without accelerators, the cure rate is only a little slower.
