NONSTICK TREATMENT FOR COMPOSITE MOLDS |
| 摘要 |
A method for rendering nonstick a mold made of composite material, including the steps of: (i) providing a mold made of a composite material including an epoxy resin; (ii) applying a fluorinated-polymer powder, having a minimum film-forming temperature of less than 300° C. and heat resistance at temperatures higher than 200° C., onto the walls of the mold so as to form a layer; and (iii) heating the resulting layer to a temperature of between 260° C. and 300° C. so as to form a continuous film, whereby a mold made of a composite material is obtained the walls of which are provided with a nonstick coating. The present disclosure also relates to the mold obtainable by said method. |

1. A method for rendering nonstick a mold made of a composite material intended for the manufacture of parts made of composite material, comprising the steps of:
(i) providing a mold made of composite material comprising an epoxy resin; (ii) applying a powder of fluorinated polymer, having a minimum film-forming temperature lower than 300° C. and heat resistance at temperatures higher than 200° C., onto the walls of the mold to form a layer; and (iii) heating the layer obtained to a temperature of between 260° C. and 300° C. to form a continuous film; whereby a mold made of composite material is obtained, the walls of which are provided with a nonstick coating. |
