Efex Thermoplastic Powder Coating. A polyethylene copolymer based thermoplastic general purpose protective coating powder with outstanding mechanical performance, impact resistance and UV-stability. May be applied by fluidized bed, hot-flocking and electrostatic application methods. Store in a cool area (under 100° F for an unlimited shelf life. VOC content is zero.

 

 

Application

For fluidized-bed dipping, preheat parts to 400° (adjust according to part thickness and mass). Dip parts in fluidized-bed of powder for 4-6 seconds. Carefully blow off the excess powder. Finished thickness should be .008" to .012". Adjust preheat, and/or dip time to control thickness. For smoother surface finish (if necessary), parts may be post-flowed for a short period of time ranging from several minutes or more depending on the amount of heat retained by the part and the post-flow temperature. Suggested post-flow temperatures are 325° to 400°. Post-flow only long enough to obtain a glossy smooth appearance. No cure time is needed. Melting point of the powder is 221°. Overheating may cause browning, degradation or embrittlement. Coated part may be put into service when cooled.

Theoretical coverage:
Sq.Ft.Lb.@.008"=24.7
Sq.Ft.Lb.@.012"=15.5.

Recommended thickness is a minimum of .008" to a maximum of .030".
