Amine-catalyzed E p o x y Resin systems are rapidly gaining in favor because of their excellent characteristics. T h e use of 2 - N P (2-Nitropropane) improves these desirable characteristics even further t o p r o v i d e : •J Greater Chemical Resistance J Lower Viscosity / Higher Solids v' More Uniform Evaporation Rate / Reduced Pinholing / Thicker Films Greater Chemical Resistance In t h e test illustrated here, 3 /4-inch steel bars were given a resin coating 6 to 8 mils thick. They were d r i e d one week, and then exposed to 3 0 % Nitric Acid. T h e unre-

Lower Viscosity T h r o u g h the use of 2-Nitropropane, it is possible to o b t a i n solutions of lower vis cosity at equal solids o r with higher solids at e q u a l viscosity, both with improved eco nomic and t e c h n i c a l a d v a n t a g e s .
cellent spray characteristics, a n d less tend ency to c r a w l . Also, substantially thicker films can be obtained a t no loss of other desirable features. 2 - N P can be used t o advantage in both amine-catalyzed sys tems and systems employing urea-formal dehyde, p o l y a m i d e s , o r phenolic crosslinking agents.
More Uniform Evaporation Rate T h e evaporation rate of 2-Nitropropane is i d e a l for spray systems, contributing favorable flow properties and excellent blush resistance with improved drying times.
Price Cut 2 2 % The new low price of 16$ per pound makes 2-NP the # / solvent buy for more and more applications. F o r complete informa tion and a laboratory s a m p l e of 2-Nitro propane, write to C o m m e r c i a l Solvents Corporation, 2 6 0 Madison A v e n u e , N e w Y o r k 16, N e w York.
