Claims13
A process for producing a reinforced phenolic resin laminate coated with a surface layer on at least one side, said surface layer consisting essentially of a furan resin coating which is directly bonded to the reinforced phenolic resin laminate, comprising depositing said coating of furan resin on a mold, then after at least a beginning of hardening, depositing alternate layers of phenolic resin and reinforcing agent, hardening the laminate, and then withdrawing resultant laminate from the mold, said laminate having no surface irregularities due to pitting or fiber projection.
A process according to claim 7, wherein the thermosetting resin is an unsaturated polyester resin.
A process according to claim 7, wherein the thermosetting resin is pigmented.
