G, Fitagerald, Lab, Philadelphia Laboratory September 9, 1949 Wf f o r o r wiAmg Pliolite is a styrene-butadiene copolymer which is made and sold by the Goodyear Rubber Company, It is offered to us in competition to chlorinated rubber, Pliolite S-5 excels chlorinated rubber in paints for brush ing and odor. It is nearly comparable fdr chemical resistance and promises a cost saving at equal build if settling proves satisfac tory so that militates can be made and do not have to be bought from Goodyear, '' Ten gallons will be made up and given out locally for basement floors* If the tests are satisfactory, it will be recommend ed for replacement of chlorinated rubber. A project will be written to request funds for development of a line of colors and for field tests. Details: Application Properties: Brushing of pliolite paints is better than chlorinated rubber painty and the lapping is equal. Both have excess flow. The chlorinated rubber paints have an objectionable odor which comes from cellusolve acetate solvent. The odor of pliolite paints (100$ H-.2C0) is better than the chlorinated rubber paint, but is still worse than regular interior architectural paints which seldom con tain more than 10$ of H-200. Film Properties: The films are about equally hard. Pliolite has better adhesion to steel than chlorinated rubber. Chemical resistance is as follows: / - Z ** Alkali Sealing Equal Alkali Resistance % HaOjH Pliolite Slightly Better Glacial Acetic Acid) Chlorinated Rubber Slightly Better 6H HgSO^ 911.
