A Method of Protecting Film and Lengthening its Serviceable Life
A process called Permafilm has been developed to prevent film damage. Impregnated into the emulsion, the effect of the compound is to toughen the emulsion while maintaining its resiliency. It does not require renewal. It deters scratches and abrasions, prevents warping, curling brittleness and negative shrinkage. Color fading is reduced to a minimum and new film pliability remains permanent.
