Studies at CSC's Lacquer Labora t o r i e s show t h a t 2 - N i t r o p r o p a n e and Nitromethane outperform the ketones in the preparation of vinyl spray formulations. Formulators can now take fullest advantage of the superiority of CSC Nitroparaffins in producing high-quality vinyl coatings. High solids vinyl formulations pre pared with 2-Nitropropane have good stability and show no tend ency to gel during storage. 2-NP rr in solutions a r e considerably lower in viscosity than mixtures based on medium-boiling ketones, allowing higher weights of solids in a given volume of lacquer and thus greater surface coverage.
Problems!
The higher evaporation rates of the ketones normally used a r e serious handicaps leading to rapid setting up of films and poor flow. Flarnmability is a constant fire hazard. The slow evaporation rate of 2-NP and N i t r o m e t h a n e s o l u t i o n s produce good flow. T h e N P ' s h a v e mild, agreeable odor and escape more rapidly when drying, eliminating odor problems. High flash points and low volatility are added safety features. 2-Nitropropane and Nitromethane are also excellent solvents for acryl ics, cellulose acetate, cellulose ace tate butyrate, and epoxy resins. A CSC t e c h n i c a l r e p r e s e n t a t i v e will be glad t o work with you on your specific problems.
