Catalog Number
ACMA00017316
Product Name
Butyl Methacrylate
Description
N-butyl methacrylate appears as a clear colorless liquid. Flash point 130°F. Less dense (7.5 lb / gal) than water and insoluble in water. Hence floats on water. Vapors heavier than air. Used to make resins adhesives, and oil additives.;Liquid;COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.
