SELF-CURABLE AND LOW TEMPERATURE CURABLE POLYESTERS
Polyesters having both α,β-unsaturated groups and moieties containing activated methylene or methine groups, such as those of beta- ketoacetate and malonate, are curable in the presence of a base catalysts to form crosslinked networks. Formulations based on such polyesters are suitable for use in co...

| description | Polyesters having both α,β-unsaturated groups and moieties containing activated methylene or methine groups, such as those of beta- ketoacetate and malonate, are curable in the presence of a base catalysts to form crosslinked networks. Formulations based on such polyesters are suitable for use in coatings and adhesive applications, and have the characteristics of curing at temperatures less than 230 ° C without the use of isocyanates.
L'invention concerne des polyesters contenant des groupes α,β-insaturés ainsi que des fractions contenant des groupes méthylène ou méthine activés, tels que ceux de beta-cétoacétate et de malonate, qui sont durcissables en présence de catalyseurs basiques pour former des réseaux réticulés. Les formulations à base de tels polyesters sont appropriées à une utilisation dans des revêtements et des applications d'adhésif, et présentent des caractéristiques de durcissement à des températures inférieures à 230 °C sans utilisation d'isocyanates. |
