What is "Fluoro-Coat" X-550? This coating is made with PTFE resin and has as good a release as other coatings made with Teflon® and heat shrinkable tubing products. The "Fluoro-Coat"™ X-550 is sprayed on while the dryer is rotating slowly, then the steam is turned into the dryer and it is heated to maximum temperature. It requires a minimum of 250º F to harden the coating.
"Fluoro-Coat" X-550 has the release characteristics of Teflon® and is the result of a five-year development effort. X-550 can be applied to the dryer and cured on site and can be field applied in less time than conventional dryer sleeves made with Teflon® FEP. This coating is ideal for dryers, even those subject to mechanical damage from pike poles
X-550 was developed to overcome the three major shortcomings of dryer covers made with Teflon® FEP:
- The life of the dryer cover is dependent upon the adhesive bond of the cover to the dryer. This bond deteriorates with time and deteriorates faster as temperature increases. X- 550 is good for continuous service up to 550ºF (288ºC).
- When a dryer cover is cut or damaged with a pike pole, it needs to be replaced. An X- 550 coating, when cut with a knife or pike pole, barely shows any damage and does not cause bond breakage leading to premature failure.
- X-550 is durable enough to be applied as a coating, thereby having as much as 20-fold improvement in heat transfer as compared to a roll cover.
