Where It Comes From
Specialty paints, sealants, fabric/floor protectors, and coating additives for durability and stain resistance [1][3].
How You Are Exposed
Workers may inhale spray mists or vapors during application/curing and get skin contact; consumers can be exposed when using spray protectors indoors or via PFAS migrating to household dust [1][2][3].
Why It Matters
Isocyanates can cause sensitization and asthma; once sensitized, very low levels can trigger symptoms. PFAS are long‑lasting; some are linked to increased cholesterol, immune effects, and certain cancers [1][2][3].
Who Is at Risk
Painters, auto refinishers, floor/fabric treatment workers; people with asthma; pregnant people, babies, and young children due to PFAS‑related developmental concerns [1][2].
How to Lower Your Exposure
At work, use local exhaust, closed systems, and proper respirators and gloves; avoid spraying when possible and monitor isocyanate levels [1]. At home, choose PFAS‑free/isocyanate‑free products, avoid spraying indoors, ventilate well, clean dust with a HEPA vacuum, and follow disposal guidance [2][3].
