Seahorse Portable Waterproof Dry Box Protective Case
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic case, 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.
Plastic degradation and leaching
Prolonged UV exposure or extreme heat can break down thermoplastic polymers and potentially release oligomers or residual monomers into contact with stored items. Risk is low under normal indoor storage but increases with outdoor use or high-temperature environments.
Rubber gasket degradation
Elastomer seals may degrade with ozone exposure, saltwater, or extended storage without maintenance, risking water ingress and mold growth inside the case. Material composition of gaskets is not typically disclosed by the manufacturer.
Adhesive or secondary material leaching
Interior foam padding or label adhesives used in case assembly may off-gas volatile compounds or leach plasticizers if present, though risk is minimal with polypropylene and typical industrial adhesives.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Microplastic shedding
No documented risk from this product category. Rigid injection-molded cases do not shed fibers like textiles, and the plastic is not designed to be heated or abraded during normal use.
Heavy metals
No recall or test data indicating lead, cadmium, or antimony in Seahorse case plastics. Modern injection-molded polypropylene is typically free of heavy metal pigments, though full material specification is not published.

What it's made of and why it matters
Seahorse dry boxes are injection-molded rigid plastic (typically polypropylene or similar thermoplastic), chosen for impact resistance and water sealing without surface coatings. This material class avoids the leaching and degradation risks associated with resin-cured epoxy coatings or polyurethane finishes found in some competing cases. The sealing performance depends on rubber gaskets and mechanical closures, not water-repellent chemical treatments, reducing contact-based chemical exposure.
The brand's record and disclosure
Seahorse (owned by Pelican Products) manufactures protective cases primarily for professional camera and equipment use and maintains a functional safety posture but does not publish chemical composition or PFAS statements. No recalls or documented chemical safety incidents are on record for this product line. The brand prioritizes durability and waterproof performance over material transparency disclosures.
How it compares in its category
Seahorse cases are mid-market rigid alternatives to lower-cost foam-padded soft cases and premium closed-cell foam options. Compared to soft fabric cases with coated nylon shells (potential for dioxane in manufacture or phthalate plasticizers), the rigid thermoplastic approach eliminates textile-based chemical risks. Hard plastic cases in this category rarely involve problematic adhesives or flame retardant treatments because they are not textiles.
If you buy it
Store the case in a cool, dry location away from prolonged direct sunlight to prevent UV degradation of the plastic over time, which can weaken seals. Rinse the rubber gaskets with fresh water after saltwater or humid use to prevent mold and bacterial growth in the seal channel. Replace gaskets if visible cracks appear or if the case no longer maintains a tight seal. Do not expose the case interior to temperatures above 60 degrees Celsius, as the plastic may soften and warp.
