Kohler, 1 am forwarding Co you a leCCer and an information bulletin sent Co me by Mr. R. P. Villeneuve of North Bend, Oregon. The information bulletin describes a patent for improving pressed-wood panel by surfacing with a compound of thermosetting resin and asbesti- jform material. Mr. Villeneuve is inquiring as to the possible interest of Union Carbide In this process. Mr. Villeneuve also sent me several samples of plywood panels which have been produced and tested under a variety of conditions and temperatures. If you feel that these samples would be of use in determining Union Carbide's possible interest in this process, I will gladly send them to you. If you have /no interest in the samples, I will return them Co Mr. Villeneuve, as he requested. Will you please communicate directly with Mr. Villeneuve. If there is anything that I can do to assist you with this, please call on me. Very truly yours. JEM:r$ Enc. \V> "' E.

Please find under separate cover some of that board. Additional tests are being carried on on the board and so far the board can resist 3000 degree heat. The boards can be made in attractive different colors and patterns. After your company looks at the board, might it be possible to return the samples to me. The owner of the board feels that a major timber company such as Weyerhaeuser Company or Georgia Pacific could produce the board jointly with Union Carbide. Union Carbide could supply the asbestos and chemical; the timber company could supply the plant facility and wood. If your company becomes interested in this matter the owner is very willing to come to an understanding with Union Carbide. Hoping to hear from you at your earliest convenience I remain Sincerely yours, x . Roger Paul Villeneuve RPV:pl (CM*" UCC 004692 IRFOltnlxIGh 13{JLLLji\L ASUtisToa pnouxTa, i:u. 3677 Pino 3tract.
