Protected Zips

What a hard life a zipper must lead.

Silver, copper, brass, zinc alloys or galvanic plating are stressed by chemicals, even by chemicals in the air. Without any protection of the metal surface the colours change and the surface structure changes.

During transport, storage and manufacturing, proper protective measures are needed. Exceptionally high temperatures or humidity causes corrosion or tarnishing.

Chemical and mechanical treatments vary greatly and can be harmful to the zip fastener. Piece dyeing of garments, bleaching, scouring, stone-washing, enzyme washing, double dyeing, steaming, centrifuging and mass laundering are all strong and dangerous processes, easily causing discolouration, corrosion, shrinkage etc.

SALMI avoids such reactions with treatments developed specifically for different metals.
