The primary concern textile engineers face when specifying magnetic hardware is moisture ingress: low-quality neodymium oxidizes rapidly, generating brown iron oxide stains that destroy finished garments. magtech® has solved this engineering bottleneck through triple-barrier hermetic sealing.

1. Hermetic TPU and Silicone Envelopes

All magtech® magnetic components are permanently sealed inside waterproof thermoplastic polyurethane (TPU) or flexible silicone casings. High-frequency RF welding creates seamless, pinhole-free envelopes that block moisture, detergents, and body sweat entirely.

2. Inherent Corrosion Resistance of SmFeN

Our flexible cords and round snaps utilize Samarium-Iron-Nitrogen alloy matrices dispersed in polymer binders. Unlike bare NdFeB which is vulnerable to atmospheric corrosion, SmFeN exhibits exceptional electrochemical stability against saltwater and machine washing.

3. Industrial Laundry Test Standards

• Tested up to 50 domestic wash and tumble dry cycles at 60°C.
• Dry-cleaning solvent resistance certified (Perchloroethylene).
• Salt spray tested for 96 hours with zero rust or structural degradation.
