c April 19, 1974 8invalco Litho Product* 800 Scholz Ifrive P. 0. Box 336 Vaudalia, Ohio 45377 Attention: Mr. K. M. lewis, Chemist cc: A. H. Vella R. Llaons J. Da Boo Matson Aehart Subject: Residual vinyl chloride monomer in Bake11te VYHH, VMCH, VYBC Solution Basins. Gentlemen: Our analyses of each of these resins Indicated no detectable vinyl chloride aonomer by a method sensitive to 1.5 parts million. This is as produced. Ibe monomer is a gas at room temperature, and off-gassing any occur, so the amount of residual aonomer could be lower by the time you receive the material. fhls is far less than the 06HA standard of 50 ppm. Very truly yours, K. 8. lane, M.D* Assistant Medical Director M.D. ucc' 067744
