Abstract
Abstract The coating of surfaces to impart gloss and protect from weathering, and the use of solvents in paint formulations, are disclosed; the following being exemplary: Compounds having the formula: ##STR1## wherein R 1 , R 2 , and R 3 are saturated alkyls having from 2 to 20 carbon atoms therein. R 1 and R 2 , or R 2 and R 3 , alternatively, may be the same and form a nitrogen heterocyclic compound such as that derived from, for example, a pyrrolidine, a piperidine or a hexahydroazepine. Exemplary compounds include: N,N-diethyldodecanamide; N,N-di-n-propyldodecanamide; 1-dodecly-2-pyrrolidone; 1-dodecyl-2-piperidone; 1-dodcylhexahydro-2H-azepin-2-one; 1-dodecanoylpiperidine; 1-dodecanoylpyrrolidone; 1-dodecanoylhexahydroazepine; N,N-diethylhexadecanamide; N,N-di-n-propylhexadecanamide; 1-hexadecyl-2-pyrrolidone; 1-hexadecyl-2-piperidone; 1-hexadecylhexahydro-2H-azepin-2-one; 1-hexadecanoylpyrrolidine; 1-hexadecanoylpiperidine; 1-hexadecanoylhexahydroazepine; N,N-dioctylbutanamide; N,N-didodecylbutanamide.
