Where It Comes From
Made and used in epoxy formulations for adhesives, coatings, electrical laminates, and composites; typically present in uncured resin mixes as a reactive diluent [1][2].
How You Are Exposed
Mainly through skin contact and breathing vapors or mists when mixing, applying, or cleaning up epoxy products at work or during DIY projects [2][3].
Why It Matters
Causes skin/eye irritation and allergic dermatitis; EU classifies it as mutagenic (may damage DNA) and carcinogenic (may cause cancer) [1][2].
Who Is at Risk
Workers who formulate or use epoxy systems (composites, flooring, electronics, boat/auto repair), laboratory staff, and frequent DIY users; people with damaged skin are more vulnerable [2][3].
How to Lower Your Exposure
Choose products without DGRE (check SDS for CAS 101-90-6); wear chemical-resistant gloves (e.g., nitrile), goggles, and sleeves; use local exhaust/ventilation; avoid skin contact and clean spills promptly; follow cure times and disposal guidance [1][3].
