The composition of the mixed solvents for airplane dopes has been discussed relative to the blush resistance and tautening property:
(1) It is reasonable to formulate the acetate dope with hydrophilic solvents which have a good solving power even when mixed with a great deal of water, but the blending of a proper amount of hydrophobic diluents such as benzene, toluene and hutanol etc. is very effective for the prevention of blushing.
(2) By the nitrate dope hydrophobic solvents and diluents are beneficially used as practiced in the lacquer industry, but it must be remenbered that the good tautening effect can only be obtained by blending a maximum amount of diluents at the sacrifice of the increase in viscosity.
