Epflor™ Modified Thermosetting Powder Coating

General Description

Epflor™ is a blend of thermosetting powder coating and polytetrafluoroethylene (PTFE). Epflor™ is available in polyester, epoxy, urethane, and hybrid chemistries. Epflor™ reduces the coefficient of friction by as much as 36.4%* compared to pure epoxy and has an increased resistance to corrosion and abrasion. Epflor™ can be applied with your current electrostatic spray equipment. Epflor™ is available in standard and custom colors.

Pretreatment

Metal components to be coated must be free of rust, grease, scale, and other contaminants. For best results, sharp corners, edges and ridges should be rounded off before the coating is applied. If chemical pretreatment is desired, appropriate chemical pretreatment based on metal type (steel vs. aluminum) should be employed.

Application

Epflor™ is typically applied at an average thickness of 3-5 mils. The electrostatic charge and air flow settings may vary depending on the substrate. Creating the fluidization of the powder in the hopper is best done by air as opposed to vibration. Corona charging is the most widely used application technique for this material.

Possible Applications

Epflor™ is an ideal coating for applications that require better lubricity or a lower coefficient of friction. Currently there are many items being coated with Epflor™. Some of those include but are not limited to luggage racks, wire shelving, cutting blades, wire baskets, shopping carts, impellers, point of purchase displays, shelving, racks, mechanical toys, playground equipment and compressions springs.

Troubleshooting

Troubleshooting
Defects	Causes	Remedy
Powder appears clumpy	Exposure to moisture	Re-mix powder on a drum roller or manually agitate in the hopper
Excessive wax-like film	Percentage of PTFE to thermosetting resin is too high	Add more Epflor™ to the hopper and manually agitate or mix in hopper.
Separation of PTFE from thermosetting resin	Improper fluidization	Use air as opposed to vibratory methods.
