PTFE Coating Process
Most of our coating systems are applied to O-rings, gaskets, & custom molded parts using conventional compressed air driven spraying techniques. The coatings are supplied as liquids and are decanted into either gravity fed or pressure fed spraying equipment.
Powder systems such as PFA and FEP are applied electrostatically to O-rings, gaskets, & custom molded parts, where the coating material (powder) and the part receive opposing electrical charges so that the powder will be attracted to the part. This is particularly useful where complex shapes are involved.
Please consult a TKF Tech Engineer about your specific application and we will use our decades of experience to formulate a solution that fits your need.
