  • What are the advantages of polyester resin?
  • This article has not yet been cited by other publications. Polyester resin has advantages in transparency and chemical resistance and is widely used in films and containers. In industrial applications, multiple conflicting properties of polyester resin mus...
  • What type of resin is used in coatings?
  • Most polyester resins used in coatings are functional resins and, as a class, normally lower molecular weight than thermoplastic polyesters used in the packaging and plastics industry, such as polyethylene (PE), polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).
  • What are unsaturated polyester resins?
  • Unsaturated polyester resins, one of the most important thermosets, are invariably produced from oil-based monomers. Their application is limited in areas where high thermal stability is required due to their low T g. Besides, these resins contain 30–40% hazardous styrene as a reactive solvent.
  • Are polyester resins heat-resistant and moldable?
  • For containers, they must be heat-resistant while being moldable. Heat resistance can be evaluated by the glass-transition temperature (Tg) and moldability by the softening point (SP). Because these two properties are correlated with each other, designing polyester resins with a high Tg and low SP is not straightforward.
  • What are environmental friendly plasticizers?
  • At present, the environmental friendly plasticizers mainly can be divided into haplotype plasticizer and polymerization plasticizer [22, 23, 24, 25], which mainly include polyol ester plasticizer, epoxy plasticizer, citrate plasticizer and polyester plasticizer and so on.
  • How do you make a polyester resin?
  • Formation of polyesters is commonly accomplished by step-growth polymerization of an alcohol with at least two hydroxy groups and a carboxylic acid with at least two carboxyl groups. Most polyester resins for conventional solids coatings comprise a diol and triol coupled with an aromatic dicarboxylic and aliphatic dicarboxylic acid or anhydride.
