Problem—Because r a w cotton is hard to wet, surface-active agents or penetrants which work effectively i n t h e presence of fireproofing salts are required. During t h e war several plants experimented with various penetrants for this type of work. Some proved unsatisfactory hecause of excessive foam which wasted solution and made working conditions difficult. Others failed to control speed of penetration resulting in imperfectly fireproofed cotton and subsequent rejectionsSolution—Use of Victawet 35B was recommended b y Victor's Research Laboratory. In practical tests, proper concentra tions of this new Victor surface active agent provided efficient wetting with practically no foaming. Penetration was controlled so t h a t t h e cotton sank just below the solution surface without collecting a t the bottom of the tank. Speed of processing was stepped up as much as 2 5 % . Production was perfect, and uniform results were demonstrated by flame tests on the finished goods. M a n y other penetration problems h a v e been solved with Victor surface-active agents. If you h a v e a problem, think first of a phosphate from Victor.
Uncontrolled penetration . . . usually accompanied by wasteful foaming . . . may cause cotton to sink to bottom of tank thereby impeding processing.
Controlled penetration with Victawet 35B produces practically no foaming. Cotton sinks just below surface . .. machine operates at maximum efficiency . . . rejects are eliminated.
