Canon WP-DC43 Underwater Camera Housing
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polycarbonate housing, rubber 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 structural degradation (optical clarity loss)
Polycarbonate yellows and becomes cloudy over 5-10 years with UV exposure and temperature cycling, particularly if stored in direct sunlight. This does not release harmful chemicals but reduces image quality and may necessitate replacement.
Rubber seal degradation and water ingress
Nitrile and EPDM seals degrade through chlorine exposure, salt crystallization, and mechanical stress. Failed seals allow water ingress, risking internal corrosion of the camera; this is a functional rather than toxicological hazard but warrants routine inspection and replacement.
Microplastic shedding from seals during use
Nitrile and EPDM seals may shed microscopic particles during compression cycles in deep water or thermal cycling. While the housing itself is not heated during use, particles shed into seawater contribute to marine microplastic burden; this is an environmental rather than direct consumer safety concern.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Modern polycarbonate used in optical housings undergoes purification steps to minimize free BPA. No published studies document BPA leaching from underwater camera housings under normal freshwater or saltwater immersion conditions.
Source, FDA ↗Heavy metals
Canon does not disclose additive packages for the WP-DC43 housing. Polycarbonate used for optics-grade applications typically avoids heavy metal colorants and relies on UV absorbers and processing aids. No recalls or contamination reports exist for this product.

What it's made of and why it matters
The WP-DC43 uses polycarbonate as its primary housing material, a rigid thermoplastic chosen for its optical clarity, impact resistance, and ability to withstand pressure at depth. Polycarbonate does not inherently leach BPA or other endocrine disruptors under normal use conditions, though older formulations may contain trace BPA as a residual monomer. The rubber seals (typically nitrile or EPDM) are designed to remain external and contact only water or the camera body, not food or skin for prolonged periods, minimizing direct exposure risk.
The brand's record and disclosure
Canon has not issued a public PFAS statement for this product line or broader chemical disclosure for camera housings. The company maintains general environmental compliance statements but does not publish third-party certifications (such as Cradle to Cradle or bluesign) for protective gear. No recalls or safety investigations specific to the WP-DC43 housing material composition have been documented in public records.
How it compares in its category
Polycarbonate underwater housings are the industry standard for this price and depth range; alternatives include acrylic (brittle, clearer optically) and aluminum (corrosion risk in salt water). The WP-DC43 sits in the mid-range for consumer-grade underwater camera protection and uses conventional materials consistent with competitors from Nikon, Sony, and third-party manufacturers. Most rigid housings in this category rely on mechanical seals rather than chemical coatings, reducing chemical leaching risk compared to soft cases with synthetic fabric.
If you buy it
Rinse the housing and seals with fresh water after saltwater use to prevent mineral buildup and seal degradation. Replace rubber seals every 2-3 years or if visible cracks appear, as degraded seals are the primary failure mode. Store dry in a cool location away from direct sunlight to minimize polycarbonate micro-stress over time. Do not expose to prolonged heat (above 60°C / 140°F) or harsh solvents, as these can compromise optical clarity and seal integrity.
