Abstract
A composition comprising 50 to 98 weight percent sulfur, 0.2 to 20 weight percent of an organic compound reactive with sulfur to plasticize sulfur, 1 to 40 weight percent mica, and 0.02 to 5 weight percent phosphorus sulfide. Preferably the organic compound used to plasticize the sulfur is dicyclopentadiene or a glycol. The composition is advantageously used to coat a concrete or metal surface and thereby obtain a coated surface which is resistant to acid attack and resistant to crazing on exposure to fluctuating temperatures.
