Spray Filler (Polyester Primer) is made on the basis of polyester resin. Because of its similarity to the two-component lining, also called polyester linings.
Sodium Carboxymethyl Cellulose (SCMC or CMC) or Cellulose Gum is an anionic water-soluble polymer; it is derived from cellulose, which is made water-soluble by a chemical reaction.
Unsaturated polyester resin is the most important polymer for production of composite materials, mainly glass fiber–reinforced plastics (FRP), but also for casting resins (nonreinforced)
