Halar

Applications

The combination of excellent corrosion-

protection and good non-sticking proper-

ties makes Halar ECTFE an extremely

efficient coating for:

Filtration tanks, vessels, pipe systemsand valves for storage and transport of

very aggressive media.

Machine parts for instance for the galvanic and semiconductor industries.

Surfaces requiring a combination of non-sticking and abrasive resistance proper-

ties are necessary.

Properties and benefits

Halar ECTFE is applied by electrostatic

powderspray. This means the total thick-

ness of the coating is adjustable. The opti-

mum layer thickness will be chosen for the

application concerned. The most important

properties and benefits of Halar ECTFE are:

Excellent corrosionprotection even incombination with high temperatures.

Resistant against abrasive media. Good non-sticking properties. Free of solvents. Halar ECTFE is used as a substitute for

very expensive alloys. If Halar ECTFE is

applied to carbon steel or a standard

stainless steel, the corrosionprotection is

the same or even better than that of very

expensive alloys.

Halar ECTFE can be mechanical-shapedafter the coating procedure.

Durable.

Halar ECTFE is a high-quality thermoplastic fluoropolymer

made by Solvay Solexis, USA. This coating is chemically

very resistant, even at high temperatures (150 C). It has

good non-sticking properties. Kersten Kunststofcoating

also applies other fluoropolymers like PTFE, ETFE, FEP

and PFA.

Construction

All constructions should be accessible for

visual inspection, grit blasting, coating and

thickness and pore control. It is also neces-

sary to round off sharp edges with a radius

of 3 mm. All parts should be totally welded

without pores, polished and welding drops

should be removed. The holes for the bolts

in flanges should be rounded and sized

2 mm. larger in diameter if corrosion-

protection is required. For more detailed

information please ask for the construction

guideline.

Electrostatic powderspray

Halar, ECTFE is applied by electrostatic

powder spaying. The coating procedure is:

Check metal products on arrival to ensure they are suitable for coating.

Grit blasting SA 21/2 or 3 and removedust.

Preheat the products in ovens to abovethe melting temperature of the powder

coating.

Apply Halar coating. After product pre-heating, the powder is sprayed on the

product. The difference in electric

potential between the powder and

surface causes the powder to be drawn

to the surface. After spraying, the

product is placed in the oven to melt the

powder. This procedure is repeated until

the desired coating thickness is reached.

Check the coating thickness and test thepore-freedom of the coating after the

construction has cooled down.
