A VOC-Free, Environmentally Friendly Finishing Solution.

This is a common myth based on early powder coating technology. While powder coatings are excellent at creating textured finishes, modern formulations and high-performance powder coating equipment can achieve a "Class A" level of smoothness that rivals liquid paint. The key is using a very fine-milled powder, applying it with a precisely controlled electrostatic gun to create a uniform layer, and having a curing oven with excellent temperature stability. The stable heat allows the powder to melt and flow out into a perfectly smooth, glass-like surface before it cross-links and hardens. A modern system from TIMS COATING can absolutely deliver a high-gloss, smooth finish.

Powder coating equipment works through a multi-stage process. 1. Pretreatment: A metal part is first thoroughly cleaned and prepared in a series of chemical washes. 2. Application: The part is then moved into a spray booth. An electrostatic spray gun applies a positive charge to particles of a dry, paint-like powder and sprays them towards the negatively grounded part. The opposing charges cause the powder to adhere to the entire surface. 3. Curing: The powder-covered part is then moved into a curing oven. The heat melts the powder, causing it to flow together and form a smooth, liquid-like layer. As it continues to heat, it chemically cross-links to form a hard, durable, and solid finish.

"Orange peel" is a textured surface defect that looks like the skin of an orange. It can be caused by several factors related to your powder coating equipment and process. One common cause is applying the powder coating too thickly. Another is improper curing; if the oven temperature is too low or the part passes through too quickly, the powder doesn't have enough time to fully melt and flow out into a smooth surface before it cures. It can also be a property of the powder formulation itself. To solve this, you need powder coating equipment with precise application controls to manage film thickness and a high-quality oven with stable, uniform heat to ensure a full, proper cure.

Powder reclamation is the process of capturing unused powder (overspray) in a spray booth and recycling it for reuse. It is the single most important feature for the economic and environmental viability of an powder coating equipment system. A high-efficiency booth from TIMS COATING uses a cyclonic separator to remove over 98% of the overspray from the air. This reclaimed powder is sieved and mixed back in with the fresh powder from the feed hopper. This closed-loop process means that unlike liquid paint where overspray is hazardous waste, powder overspray is a reusable raw material, drastically cutting material costs and waste disposal fees.
