Abstract
A process for applying a cover layer based on thermosetting resin to objects of thermosetting resin. The process is characterized in that a shape imparting support face is heated to a temperature of 90.degree.-200.degree. C. and then is provided with a cover layer of a thermosetting resin with catalyst. After hardening the cover layer and cooling below 90.degree. C. a basic layer thermosetting resin is applied and hardened.
Claims7
A process for manufacturing objects having a cover layer and an underlying basic layer bonded thereto, each layer being formed from a thermosetting resin, using only a shape-imparting support face to which at least said cover layer of thermosetting resin is applied, wherein said process employs the combination of steps of:
- a. heating said support face to a temperature between 90.degree. C. and 200.degree. C.;
- b. forming a cover layer by applying a first thermosetting resin as liquid or solid fine particles along with a catalyst to said support face, and causing any solid resin to melt and effecting polymerization and curing of said first resin;
- and
- c. forming a basic layer by applying a second cross-linking thermosetting resin to said formed cover layer and then curing said second resin while maintaining a support face temperature below 90.degree. C. whereby said second resin forms said basic layer bonded to said cover layer.
