PfAS Benifits

pFAS^® Coating Technology is offered as an alternative to conventional roll coating to make the coil coating process safer, more reliable and more profitable. Coating is applied without the use of metering or pick-up rolls. Coating film thickness is more uniform across the width and through the length. The pFAS^® coater set-up can eliminate Ribs that must flow out to obtain high gloss or uniform appearance. This can minimize the length or even the need for a flowout zone. Conversion to pFAS^® Coating Technology is not simply improving an existing Coil Coating Line. The old rules for line utilization no longer exist. The paradigms for theoretical capacities and costs are broken for the Coil Coating Line. Products can be changed from Good Metal to Good Metal in under two minutes. Meeting new customer demands for quicker delivery requirements and smaller coil sizes can be achieved.

Hands off coating changes

1.	Elimination of operator exposure to coating fumes
2.	Increases up time
3.	Eliminates need to stop line
4.	Eliminates associated scrap in the line if done on the fly
5.	Automated Applicator Roll clean-up during product change
6.	Accurate read-out for start-up Film thickness

Precise controlability of critical process variables for film thickness control

1.	Provides control to insure coating thickness is within specification
2.	Permits tighter film thickness control with reduced variablity
3.	Accurate real time film thickness measurement

Insures higher quality coating is delivered to the web

1.	All coating can be filtered before entering the pFAS^® system. Excess material is returned for refiltration before being reintroduced to the applicator roll. This differs from conventional roll coating. Coating in a pan can collect contaminates from the atmosphere, coating dry-out, coating foaming or contaminates from web contamination and can be deposited back on the applicator roll and then the web.
2.	Temperature of all material delivered to the applicator roll can be controlled although not needed.
3.	Film thickness control is independent of temperature and viscosity.

Improved surface appearance/reduced scrap.

1.	Defects such as skips and voids are eliminated because the sources of these defects are eliminated. These defects result from problems in the pan or interactions between roll nips. Both sources are eliminated.
2.	The application process can be rib free. This eliminates the need for a flow out zone, improves appearance and/or permits application with more viscous materials

Permits operation of higher line speeds. Elimination of rolls in a coating pan eliminating problems associated with sheet contamination, elimination of the powered nip safety hazard and generally eliminates most clean-up problems.

For a new coating line the initial cost for the coating process is reduced by over 50% where dual coaters or traversing coaters are conventionally used. Building and foundation costs are dramaticly reduced. Long term operator accessibility and process management is simplified with elimination of a second coater machine. In many cases the need for a second coater operator can be eliminated with elimination of a second coater head. A single pFAS^® coater machine can provide nearly the same or better product change times with much less long term maintenance. A pFAS^® coater on the bottom head can provide rapid product changes where there are no other viable solutions.
