Merits and demerits of thermoset resins.

Type of Resin	Advantages	Disadvantages
Epoxy resin	High water resistance High thermal and mechanical properties Low curing time Durability	Difficult to process Corrosive amine hardener More expensive than vinyl ester
Vinyl ester	High chemical resistance High mechanical properties than polyester	High curing shrinkage High styrene content Needs post curing More expensive
Polyester	Lowest cost Easy to use	Limited access moderate mechanical properties Huge curing shrinkage High gas emissions
Phenolic	High fire retardance	Hard to develop
