Canon WP-DC1 Waterproof Case
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polycarbonate, 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 stress-cracking and degradation
Polycarbonate is susceptible to damage from UV exposure, impact, and contact with certain solvents. Over time (5-10+ years), the plastic may yellow, become brittle, or crack, compromising waterproof integrity and potentially releasing small fragments; this is a mechanical failure mode, not chemical leaching.
Gasket and seal material degradation
The WP-DC1 uses rubber or silicone gaskets to maintain the waterproof seal. These materials can harden, crack, or degrade over years of UV exposure and thermal cycling, leading to water ingress; replacement gaskets may not be readily available for this legacy model.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
While modern polycarbonate resin used by Canon is typically BPA-free or trace-only, the product's age and lack of explicit material certification means BPA presence cannot be ruled out with certainty; however, no documented exposure risk exists because the case does not contact food or drinking water.
Source, FDA ↗Microplastics
Polycarbonate cases do not shed microplastics during normal dry storage or handling. Risk of fragmentation is limited to mechanical damage (cracking, breaking) that would occur visibly and suddenly, not as invisible particulate release.
Source, EPA ↗Chemical leaching into water during immersion
Polycarbonate resin itself does not leach meaningful quantities of additives into water during temporary or repeated waterproof use. The case is designed for intermittent submersion to protect electronics, not as a long-term water storage container, so chemical migration is not a documented concern.
The full breakdown
What it's made of and why it matters
The WP-DC1 is constructed from polycarbonate, a rigid engineering plastic chosen for optical clarity and impact resistance in camera protection. Polycarbonate does not contain BPA, BPS, or phthalates in the resin itself, though older formulations occasionally included BPA as a processing aid. Canon's polycarbonate cases are not a material linked to documented leaching into water or contact food applications. The material's main weakness is UV degradation and stress cracking over years of intense sunlight exposure, not chemical leaching.
The brand's record and disclosure
Canon has not published detailed material safety disclosures or PFAS statements for this legacy camera accessory line. The company maintains general product safety certifications but does not routinely highlight polycarbonate sourcing or additive transparency. No recalls or documented contamination incidents are on record for the WP-DC1 specifically. Canon's silence on PFAS in waterproof cases reflects an older era of accessory documentation rather than evidence of problematic chemistry.
How it compares in its category
Polycarbonate waterproof cases are a standard, mid-tier choice between cheaper PVC (which can off-gas phthalates) and premium rubberized or silicone-lined cases. The WP-DC1 competes directly with other polycarbonate rigid housings like Pelican knock-offs and generic underwater boxes, all of which carry similar low chemical hazard profiles. The waterproof seal depends on mechanical gaskets and latches, not chemical coatings, which avoids PFAS or other finish hazards common in treated fabrics. Polycarbonate yellows and becomes brittle over 5-10 years, a cosmetic rather than safety issue.
If you buy it
Store the case indoors in cool, dry conditions away from direct sunlight to slow UV degradation and maintain optical clarity. Do not expose it to solvents, acetone, or strong household chemicals, which can stress-crack polycarbonate. Clean gaskets with mild soap and water, and inspect them annually for tears or hardening; replace if sealing fails. Avoid dropping or subjecting it to extreme temperature swings, as polycarbonate becomes brittle in cold and can deform near heat sources.
