Can BioThane Get Wet? Performance in Water and Humidity

How does moisture exposure affect the structural integrity of this material over time?

Moisture does not degrade the core polyester webbing because the TPU or PVC shell acts as a hermetic seal. Unlike organic materials that swell or rot, this synthetic composite maintains its tensile strength even after years of constant submersion. Many users assume that frequent wetting will eventually cause the inner core to fray or weaken from the inside out, but the material is chemically inert to water. As long as the outer sheath remains intact and free of deep gouges, the structural integrity stays consistent regardless of how often it gets wet.

Is the webbing prone to mildew or mold growth when left in damp conditions?

No, the material is inherently resistant to microbial growth because it lacks the porous surface required for mold spores to take root. Since the non-porous coating prevents moisture from reaching the inner fibers, the material remains inhospitable to fungi, even when stored in high-humidity environments exceeding 90 percent.

What are the recommended cleaning procedures after the material has been submerged in salt water?

Rinsing gear thoroughly with fresh water is the most effective way to prevent salt crystallization and subsequent hardware degradation.

• Fresh water: Use a pressurized spray or a deep basin to flush out every crevice where salt crystals might hide.
• Soft cloth: Wipe the entire surface area with a clean, damp towel to remove any microscopic salt residue that remains after the initial rinse.
• Air drying: Hang the gear in a well-ventilated area away from direct, high-intensity sunlight to make sure the hardware and webbing dry completely.
• Lubricant: Apply a small amount of silicone-based oil to the rivets or buckles once the gear is bone-dry to displace any lingering moisture.

Does the coating prevent the absorption of liquids and odors compared to traditional leather?

Yes, the non-porous coating acts as a complete barrier, keeping the material at a 0 percent absorption rate for both liquids and odors. This differs significantly from leather, which can absorb its own weight in moisture and trap bacteria that lead to permanent, deep-seated odors over time.

How quickly does the surface dry after being exposed to rain or water?

The surface dries almost instantly because it is non-absorbent, meaning water beads up and rolls off rather than soaking in. In practical terms, a quick wipe with a towel after a heavy rainstorm leaves the gear ready for immediate use. For example, a leash used during a walk in a downpour will feel dry to the touch within seconds of being wiped down.

However, there is a nuance regarding the edges. While the flat surfaces dry immediately, the cut edges where the webbing is exposed during the manufacturing process can hold a tiny droplet of water. While these edges are typically sealed during production, they might take a few minutes longer to evaporate than the smooth face of the strap.

Are the hardware components resistant to rust or corrosion when frequently used in wet environments?

Hardware resistance depends entirely on the specific metal alloy used, as not all components are created equal in their ability to withstand oxidation.

• Stainless steel: This material is the most reliable choice for saltwater environments because its high chromium content creates a passive layer that prevents rust.
• Brass: These fittings are highly resistant to corrosion, though they may develop a dull patina or greenish oxidation over time when exposed to salt.
• Zinc die-cast: These cheaper, plated options are prone to pitting and rust within a few weeks of consistent exposure to salt spray or ocean water.
• 316 grade: This specific designation of steel is the industry standard for marine applications, offering the highest level of protection against pitting in harsh, saline conditions.

Does the material lose its flexibility or become brittle after repeated cycles of wetting and drying?

The material retains its original flexibility regardless of how many times it undergoes wetting and drying cycles. Unlike leather, which loses its natural oils and becomes stiff or cracked after getting wet, this synthetic webbing remains supple and pliable in both freezing temperatures and extreme heat. For instance, a collar will maintain the same degree of softness in the middle of winter as it does on a hot summer day.

The only exception occurs when the material is subjected to extreme, prolonged heat exposure, such as being left on a hot dashboard or near a heating element. While water itself does not cause brittleness, excessive heat can eventually cause the TPU coating to lose its elasticity and become rigid. Keeping the gear away from direct heat sources makes sure it stays flexible for the duration of its service life.
