Lubrication of 16-mm Films

Abstract

This paper describes materials suitable for the lubrication of 16-mm films. Wax-carbon tetrachloride formulas are given, together with the precautions which must be observed in using them. Slower-evaporating wax-isopropyl alcohol mixtures are described for use where additional drying space is available. By the use of these formulas, 16-mm films can be adequately lubricated at a material cost of $0.01 per 400 feet of film. — New formulas using Freon, a rapid-drying, noninflammable solvent, of extremely low order of toxicity, are suggested. A suitable surface treatment for use with films to be run on repeater mechanisms is described.
