Nikon WP-CP3 Marine Case for Camera
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polycarbonate/rubber with waterproof seals, 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.
Polycarbonate degradation over time
Polycarbonate can become brittle and lose optical clarity after prolonged UV exposure or thermal cycling. This affects waterproof integrity only if the rigid body cracks; it does not release chemicals into the stored equipment.
Rubber gasket hardening and seal failure
Natural and synthetic rubber seals gradually harden with age and exposure to heat or ozone, reducing waterproof effectiveness. This is a functional failure mode, not a chemical toxicity issue, but replacement gaskets are required to maintain protection.
Microbial growth in sealed moisture pockets
If the case is closed while wet or stored in high humidity, trapped moisture can support mold and bacterial growth on internal surfaces. This poses no direct chemical hazard but can damage equipment and create odors; regular drying is the simple prevention.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
BPA does not migrate from polycarbonate at room temperature during typical protective case use. No heating, acidic contact, or repeated flexing occurs in a rigid protective case, so leaching risk is negligible.
Source, FDA ↗Formaldehyde / VOCs
No formaldehyde-based curing resins or volatile plasticizers are known to be present in modern camera case gaskets. Off-gassing, if any, occurs during initial manufacturing and dissipates long before retail purchase.

What it's made of and why it matters
The WP-CP3 is constructed from polycarbonate (a rigid plastic) paired with rubber seals and gaskets. Polycarbonate itself does not leach BPA under normal storage conditions when used as a protective case at room temperature, since it is not in direct food contact and not heated during use. The rubber components (seals, gaskets) are inert when dry and do not off-gas volatile organic compounds at ambient conditions.
The brand's record and disclosure
Nikon has not published formal chemical safety disclosures or materials certifications for this product line. The company does not advertise PFAS avoidance or third-party safety testing for protective cases. This silence reflects typical industry practice for protective gear rather than a documented safety concern, but transparency is limited.
How it compares in its category
Polycarbonate hard cases are the standard material in waterproof camera protection. This choice avoids known concerns with vinyl (phthalate softeners) and PVC alternatives. The sealed design with mechanical gaskets, rather than waterproof coatings, eliminates exposure to Teflon-type coating or Teflon-family coating treatments common in textiles and some other case types.
If you buy it
Keep seals and gaskets clean and dry when not in use to prevent mold and bacterial growth in trapped moisture. Do not expose the case to extreme heat (above 60 degrees Celsius) for extended periods, as polycarbonate can degrade and become brittle. Inspect gaskets annually for cracks or hardening; replace them if visible wear appears. The case itself should last many years if stored in a cool, dry location away from direct sunlight.
