Non-stick coatings Ceramic coatings
■ Excellent non-stick properties ■ Hardness = 40-65 HRC
■ High wear protection, easy cleaning ■ Electrical insulation
■ On request with FDA approval ■ High layer thickness of up to 2 mm / Rz 2-50 μm
■ Various surface qualities ■ High temperature resistance
■ Good grip qualities ■ Wear-resistant, cut-resistant and grindable

Rubber coatings Hard metal coatings
■ Design according to customer specifications (various ■ Very hard layer (55-72 HRC)
Shore hardnesses, colours, finishes) with grip, non-stick, ■ Cut-resistant
wear protection, electrical conductivity and anti-static ■ Higher durability compared to hard chrome
■ e.g. NBR, EPDM, PU, silicone NR, XNBR, SBR, CR (3-5x service life)
■ Low porosity <1%; Rz 1-25 μm / grindable
■ Resistant to erosion, abrasion and oxidation

Hard anodisation Anodisation E6/EV1
■ Increased protection against corrosion and wear ■ Medium protection against corrosion and wear
■ Layer thickness 50+/-10 μm
