Powder Coating

Pinholes in powder coating are small crater-like defects that can appear after curing, often caused by trapped gases, surface contamination, outgassing substrates, or over-baking. This square sample card visually represents pinholes for training and quality documentation. BLUETEE mitigates pinholes through rigorous surface prep (cleaning, degassing, proper pretreatment), controlled film builds, optimized curing profiles, and selecting formulations with good degassing characteristics. For production teams, adopting consistent blasting/pretreatment, proper substrate venting, and accurate temperature profiling greatly reduces the risk. With process discipline and the right powder chemistry, BLUETEE delivers smooth, durable, and aesthetically consistent coatings across industrial, automotive, and architectural applications.
