OPTI SHIELD by Coats OptiThrough its Research and Development department, Coats Opti has developed a unique, advanced formula which on the one hand makes the zip’s teeth and slider resistant to corrosion caused by tanning chemicals and exposure to atmospheric agents, and on the other hand improves the zip’s runnability by reducing friction.
Metal zips used in accessories and clothing are prone to oxidation and corrosion caused by the tanning chemicals present in leather. This causes them to jam, and even ruin the appearance of the product. The Shield proprietary finish is the most advanced range of zips, and protects the electroplated finish from chemicals, minimising the damage caused by normal abrasion. Shield combines specially engineered chemical and mechanical properties to improve the appearance and durability of the zip, both for finishes in precious metal (gold, palladium, ruthenium) and standard metals (brass, nickel, etc.)
These product innovations are concentrated in the LUX and SimmiS SHIELD pre-sheared zips in sizes of 4, 6, and 8 mm, available in all finishes and colours present in the electroplating catalogue and with a choice of shiny or matte finish and in the version with symmetrical teeth.
