Description
Colorless liquid or solid (below 55 degrees F) with a distinctive, acrid odor; Note: Shipped with an inhibitor (e.g., hydroquinone) since it readily polymerizes; [NIOSH]
Sources/Uses
Acrylic acid is used to manufacture acrylic resins and acrylates for leather coatings, paints, and adhesives. [ACGIH]
Comments
Liquid causes second degree burns after contact for a few minutes. [CHRIS] Can cause pulmonary edema after heavy inhalation exposure; [ICSC] [Daecke C, et al. Contact urticaria from acrylic acid in Fixomull tape. Contact Dermatitis. 1993 Oct;29(4):216-7. No abstract available.] Corrosive to skin; [Quick CPC] Acrylic acid, stabilized (UN2218) has warning of explosive polymerization; [ERG 2016]
