CORROSION PROTECTION COATINGS

HÜNI + CO offers a wide range of different corrosion protection coatings adjusted to your individual application in order to ensure the best corrosion protection possible. Beside chemical resistance as a primary function, our coatings also meet other requirements like an anti-adhesive surface, food conformity, temperature resistance, wear resistance or electrical discharge. Furthermore we can realize different colourings in order to meet your individual demands.

DESCRIPTION

The PROCO – PA 11 process is particularly suitable for corrosion-proof coating of small and complicated work pieces. The high layer thicknesses provide maximum protection against chemical and mechanical loads and are warm to the touch (e.g. sports equipment, door handles) in addition to an excellent appearance. Resistance against alkalis, saline solutions greases, oils and solvents is good and usually sufficient for chlorinated hydrocarbons, oxidising agents and diluted acids.
Types which are physiologically stable and authorised for contact with food are available.

Processing of PA 12 (VESTOSINT®) at customer’s request.

TYPICAL FEATURES

Smooth surface
Good sliding properties
High elasticity
High corrosion protection
High insulation index
High wear resistance

AREAS OF APPLICATION

Springs, pump housings, gear housings, washing and dishwashing machines, vehicle construction (cardan shafts), coating pans, dispensing systems, tools, handwheels, fixtures and fittings, filter plates, slurry treatment and waste water systems, wire and mesh industry, pressed parts, sports equipment, indoor/outdoor pipelines, tanks, rotary valves.

DESCRIPTION

These powder coatings are used wherever normal paintwork requirements cannot be met. They offer good resistance to diluted acid or lye as well as to aggressive cleaning agents.
Depending on the colour, the coatings are suitable for contact with foodstuffs, drinks and tobacco. We use our Proco – Pes process on components exposed to natural weather.
We use our Proco-EP/KU 600 process (coating thickness 1.500-2.500 μm, colour blue- grey) as insulation coating for live components.

TYPICAL FEATURES

Good anti- corrosion
Impact- and shockproof
Smooth surface
Excellent adhesion to iron, zinc, aluminium, non-ferrous metals, glass, ceramics
