    Description
    Isobutyl methacrylate is a colorless liquid with a flash point of 120°F. When heated to high temperatures it may release acrid smoke and fumes. If it is subjected to heat for prolonged periods or becomes contaminated, it is subject to polymerization. If the polymerization takes place inside a container, the container may violently rupture. The vapors are heavier than air. It may be irritating to skin and eyes and produce a narcotic effect. It is used in making acrylic resins.;Liquid
