Abstract:

Ethylene glycol monomethyl ether methyl cellosolve, a good solvent for organic polymers, has been evaluated by the Navy as a jet fuel anti-icing additive. The effects which such an additive might have on organic coatings applied to the interior of large underground fuel storage tanks could influence any decision on its adoption. Steel and concrete panels coated with lining materials currently used by the Navy were exposed to aqueous solutions of the anti-icing additive in the presence of JP-5 for up to two years. Results indicate that 20 to 60 additive concentrations in the water phase inhibited blister size andor density by comparison with water immersion alone. Although the presence of additive in the test media resulted in a slight softening of the Type 53 lining for concrete tanks, there is no significant difference in adhesion of this film to concrete when immersed in water alone or with additive concentrations up to 60. No adverse effect of the additive on linings applied to steel or concrete is anticipated in the normally encountered concentrations of 20 to 40. It is concluded that the presence of this anti-icing additive in concentrations normally to be encountered could extend the service life of the coatings.
