Manufacturers of Kappa Cellulose Acetate Rayon Tapes.

Superior Varnishing Characteristics.

Complete impregnation. Higher dielectric. Less varnish build-up. Fewer varnish dips. Superior finish.

These definite improvements in the results obtained with the new Kappa Cellulose Acetate Rayon Tapes, when varnish-impregnated by standard methods, have been proved by both authoritative impartial laboratory tests and by the experience of many leading electrical manufacturers now using Kappa Tapes in regular production.
