Samsung Misty Band for Galaxy Watch9 (Watch8)
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes silicone elastomer band, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial or fungal growth on elastomer
Silicone is hydrophobic and non-porous, limiting microbial adhesion, but sweat and dead skin cells trapped under a continuously worn band can create localized moisture. Regular cleaning prevents this risk.
Degradation of band material under UV or heat stress
Prolonged exposure to direct sunlight or heat may cause silicone to become brittle or lose elasticity over months to years. This is aesthetic and functional degradation rather than a direct toxicological hazard.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Skin irritation or contact dermatitis from dyes or additives
No reports of allergic reactions or irritation from the Misty Band. Silicone elastomers used in wearables are typically free of azo dyes and common allergens, though individual sensitivities vary.
Leaching of colorants or processing residues
Silicone elastomer is chemically stable post-cure; colorants are bound into the polymer matrix rather than applied as surface coatings. Migration into sweat under normal wear is not established as a concern for this material class.
Formaldehyde / VOCs
Medical-grade silicone used in wearables is cured without formaldehyde-releasing agents. No evidence of residual formaldehyde in finished silicone elastomer bands.

What it's made of and why it matters
The Misty Band is constructed from silicone elastomer, a synthetic rubber polymer prized for flexibility, durability, and skin compatibility. Silicone does not readily leach into skin under normal wear conditions and is considered a low-migration material by FDA standards for food contact and dermal use. Unlike vinyl or PVC elastomers, silicone lacks plasticizers such as phthalates that require chemical migration to maintain flexibility. The material's stability and inertness make it a standard choice for smartwatch bands and medical-grade wearables.
The brand's record and disclosure
Samsung does not publish detailed material safety disclosures for wearable bands in the same manner as some competitors, but maintains general compliance with consumer safety regulations across major markets. No recalls or safety controversies have been established for Samsung smartwatch bands or the Misty Band specifically. The brand's silence on PFAS is not unusual for silicone elastomer products, as the material class does not typically employ PFAS water-repellent coatings; the water resistance comes from the inherent hydrophobic nature of silicone itself.
How it compares in its category
Silicone bands are now standard in the smartwatch accessory market and represent lower concern among elastomer choices compared to vinyl or rubber alternatives. Most major competitors (Apple, Garmin, Fitbit) offer comparable silicone options. Unlike cloth or leather bands, silicone avoids formaldehyde-based tanning agents and dyes. The Misty Band's material profile aligns with industry best practice for skin-contact wearables.
If you buy it
Wash the band regularly with mild soap and water to prevent bacterial buildup in sweat residue, especially if worn continuously. Avoid prolonged exposure to extreme heat (above 60°C / 140°F) or direct sunlight for extended periods, as this can degrade silicone elasticity over time. Replace the band if it becomes visibly cracked, sticky, or shows loss of flexibility. Inspect the attachment points monthly to ensure the band seals properly to the watch body.
