Product Name
Butyl acrylate resin
Description
Butyl acrylate appears as a clear colorless liquid with a sharp characteristic odor. Very slightly soluble in water and somewhat less dense than water. Hence forms surface slick on water. Flash point 105°F. Density 7.5 lb / gal. Used for making paints, coatings, caulks, sealants, adhesives.;Liquid;COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.;Clear, colorless liquid with a strong, fruity odor.;Clear, colorless liquid with a strong, fruity odor. [Note: Highly reactive; may contain an inhibitor to prevent spontaneous polymerization.]
