The resins manufactured by Omar Coatings are liquids classified as heat-resistant. Once they have been hardened by the catalysts, they cannot return to their original state and become insoluble solids..
Resins whose chain is formed by ester functions obtained by the polycondensation of unsaturated dicarboxylic acids with glycols. The polyester resins are liquid at room temperature and can be turned into solids by the addition of an accelerator and a catalyst.
An alkyd resin is basically a polyester whose main chain is modified with molecules of fatty acid or oil, which give long, short and medium types according to oil length.
These are polyester resins with an abundance of free hydroxyls, supplied undiluted in liquid form to enable the reaction with the isocyanate resins.
