CAS 68239-43-0

2-Propenoic acid, 2-methyl-, 2-ethylhexyl ester, polymer with α-fluoro-ω-[2-[(2-methyl-1-oxo-2-propen-1-yl)oxy]ethyl]poly(difluoromethylene), 2-hydroxyethyl 2-methyl-2-propenoate and N-(hydroxymethyl)-2-propenamide

This fluorinated acrylic copolymer is used in stain- and water‑resistant paints, sealants, and textile/paper coatings. The polymer is low‑volatility, but unreacted acrylate ingredients and wear particles can irritate skin and lungs, and fluorinated coatings can contribute PFAS to indoor dust [1][2][3].

Where It Comes From

Specialty surface treatments and coatings for fabrics, leather, paper/packaging, flooring, and architectural/industrial paints [1].

How You Are Exposed

Vapors/mist during application or curing, skin contact with uncured product, dust from sanding/abrasion, and household dust that can contain PFAS from fluorinated coatings [2][3].

Why It Matters

Short‑term eye, skin, and airway irritation; some acrylates can trigger allergic skin reactions in sensitized people [3][4]. Certain PFAS build up in people and have been linked to immune and cholesterol effects [2].

Who Is at Risk

Workers making/applying coatings; DIYers in poorly ventilated spaces; remodelers who sand treated surfaces; young children who ingest dust; people with asthma or skin sensitivities [2][3][4].

How to Lower Your Exposure

Choose PFAS‑free/stain‑resistant‑free options when possible [1][2]. Use good ventilation, follow label/SDS, and wear nitrile gloves and eye protection [3][5]. Avoid dry sanding; use wet methods and HEPA vacuums. Clean dust with HEPA vacuum and damp wiping; wash hands before eating [2][5].
