009 Moss Green A.D. Dipping Enamel (S0-b909) pently, Quaker Stretcher Company, a manufacturing firm of several items, tain stretchers being the main one, requested the laboratory to develop finish which would meet their requirements. je article to be finished was a six foot length of 22 gauge steel formed to a channel one-half inch wide and one-quarter inch deep, having a led and crimped edge running down the entire length of one side. This esented numerous obstacles where a good drain, non-color floating and :ast setting, dipping enamel was desired, representative of this firm was invited to spend a few days in the oratory, bringing with him the necessary equipment for an actual full ale dip test. ter several attempts at dipping and adjusting solvents, SG-U90? was eloped having these characteristics: good tank stability, good drain and ng, non-silking, no color float, clean drip, having no excessive bead the bottom of the drain. This material also has the quality to air "print-free in one hour, and to be silk screen stenciled in one hour a half. ;ts were conducted for salt spray resistance on the unscored finish for 'a hundred hours without being a complete failure. Humidity test one pusand hours and weatherometer tests showed fair resistance. one white enamel was developed at a later date having the same quality 'the green except that dipping reductions are not quite the same, formance was excellent.

Johnson Drier Substitute ause* of the recent law passed by the State of Maryland requiring non,,c. paints-, an attempt has been made to find a substitute for lead ium naphthenate, a nitrogen containing compound, and several aldehydes all tried with success. Twice as much of the $% calcium naphthenate .9 25% lead naphthenate is a good average to use. In the case of the three driers, straight per cent for per cent substitution is a good to start. bove tests were only made for air dry and low bake, (120 F.), ,.lations. F, Levy -!! CLD012784
