The Problem-Solution Series: Part 13

By

Limited Disposition?

Experiencing limited disposition due to charged particles? We’re here to help!

Problem: Charged powder coating particles are limiting further disposition onto the surface of the part.

Origin/Cause: The part is inadequately grounded creating a surface charge that repels the powder.

Solution: Check contact areas to ensure that there is no buildup of cured coating, grease, or other insulating material that impedes ground continuity. Also, make sure to avoid heavy powder buildup.

Second Origin: The high voltage is creating a strong magnetic field.

Solution: Reduce the voltage to the electrical field to eliminate or reduce electrostatic rejection.

Third Origin: If the gun is too close to the part, it will create a strong magnetic field.

Solution: Simply move the gun and part further from one another.

TCI's formulation lab uses innovative technology to enhance the economic and environmental benefits of our offerings. One way we do that is by offering fast cure technology. The benefits of these cures include:  1) Energy Savings: Increased line speeds = reduced manufacturing hours 2) Maximized Output Profit: By coating more parts in the same amount of time, the manufacturing costs  is lowered improving the profit margin per part 3) Eliminate bottlenecks associated with cure time/temperature restraints of the power application/cure process 4) Reduced carbon footprint in combination with reduced operating hours The faster you can cure, the less you need to run the cure oven, and the greener your powder coating process will be.  Discover our stock Fast Cure (FC) product offerings on our color card here:  https://tcipowder.com/products/color-cards/stock-color-card/

Fabtech is always an exciting and electrifying show, and this year in Chicago was no different. The event attendees totaled over 48,000 from 95 different countries. TCI utilized the same booth we did last year, a 20’ x 20’ space with graphics highlighting our values: innovation, service and performance, and also our 7 core markets. This year we brought TCI product literature such as stock color cards, case studies and RAL Decks. We also used this opportunity to launch our new high-performance FenceCoat Gen II platform and highlighted it with various fence parts coated in popular architectural colors. Other powder coated parts we displayed included domes and speed shapes. The bright colors and variety of textures on these pieces brought much attention and people were intrigued by all the options that powder coatings can offer. Our favorite part of the show was getting the opportunity to chat with attendees and the other exhibitors involved in the Finishing Market. I...
