use as an alternative to ‘shot-fire’ in thicker steels
up to 22.0 thick.
With washer

What is
EvoshieldTM
EvoshieldTM is our trade marked fastener coating. EvoshieldTM is a non-organic, tri-layered
ceramic surface coating developed to attain optimum performance in the various pollutive and
atmospheric conditions that cause corrosion.
Layer 1: metallic zinc
Layer 2: high-grade anti-corrosion chemical conversion film
Layer 3: baked ceramic top coating
The distinguishing feature of EvoshieldTM is the tight joining of the baked ceramic top coating and
the chemical conversion film thanks to the cross-linking effect. These layers are bonded together
with the metallic zinc layer through chemical reactions, and this unique method of combining
layers results in a rigid and dense combination of the coating films. EvoshieldTM treatment does
not attribute its anti-corrosion properties to merely a single material, but the synergy of these
three layers, which combined have superb rustproof qualities.
Compatible with metal coated and painted surfaces, fasteners coated with EvoshieldTM are
resistant to acid and alkaline attack, galvanic corrosion and hydrogen embrittlement. These
fasteners conform to corrosive gas test standard (Kesternich) DIN50018 and give a salt spray fog
test to exceed (JISZ2731) 1,000 hours (ASTM B117).
