Abstract

In accordance with the present invention there is provided a corrosion resistant surfacing veil of a thermoplastic fluoropolymer, and corrosion resistant reinforced thermoset plastic laminates having a surfacing veil of a thermoplastic fluoropolymer.

Claims

1. In a reinforced corrosion resistant laminate, the improvement comprising incorporating therein a surfacing veil of a thermoplastic fluoropolymer.

2. The laminate of claim 1 wherein said thermoplastic fluoropolymer is a copolymer of ethylene and chlorotrifluoroethylene.

10. The laminate of claim 1 wherein said laminate is contact molded.

13. The laminate of claim 1 wherein said laminate is made from thermosetting resin.

14. The laminate of claim 13 wherein said thermosetting resin is a vinyl ester resin.

3. A chemically resistant plastic laminate comprising:

a. an initial layer of a thermosetting resin having a surfacing veil or mat of fibers of a thermoplastic fluoropolymer therein, and

b. a second layer of a thermosetting resin having glass reinforcing fibers contained therein.

4. The laminate of claim 3 wherein said thermoplastic fluoropolymer is a copolymer of ethylene and chlorotrifluoroethylene.

5. The laminate of claim 4 wherein said laminate is contact molded.

6. The laminate of claim 5 wherein said thermosetting resin is a vinyl ester resin.

7. A chemically resistant contact molded plastic laminate comprising:
