POLYESTER RESINS

Polyester is often reffered to as fiberglass. Polyester resins are unsaturated synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols.
Unsaturated polyesters are condensation polymers formed by the reaction of polyols. 
Polyester resins are thermosetting.
Polyesters offer ease of handling, low cost, dimensional stability, as well as good mechanical, chemical-resistance and electrical properties.
Polyester resins are the least expensive of the resin options, providing the most economical way to incorporate resin, filler and reinforcement. 
They are the primary resin matrix used in SMC (sheet molding compounds) and BMC (bulk molding compounds).
The low viscosity and raw material cost of polyesters make the additions of filler and reinforcements a matter of practicality.
The components are polyester resins are pigments,resins,additives and reflective beads.

Advantages 
Long lasting.
Durable 
Relatively affordable
Works well with concrete
Does not discolor harshly

Disadvantages
Oxidizizes 
Mixing is hard
The solvent is flammable 
It is hazardous waste
Takes time to set up.

That is just a brief discussion about polyester resins.
