It’s a common question many people have when looking to powder coating their items. How long does powder coating take to dry?
As with any type of coating, the answer depends on the specific situation. Here are some factors that can influence how quickly your powder coat will dry:
Powder coating is sensitive to temperature and it typically needs a minimum of 65 degrees Fahrenheit in order for it to properly cure. If the temperature falls below this, then the curing process could be substantially slowed down or even halted completely.
High levels of humidity also adversely affect curing time as moisture can cause issues with adhesion and paint defects. While there are ways to mitigate this issue (such as using a dehumidifier), it should still be taken into consideration.
Thickness Of The Coating
Generally speaking, thicker coats of powder take longer to cure than thinner coats. This is primarily because a thicker coating will require more heat and energy in order to be fully cured.
In general, most powder coatings can take anywhere from 4-24 hours to completely dry and cure depending on how thick the coating is and how warm it is outside. If you’re looking for an exact number, then it’s best to consult with your powder coater who can give you an accurate estimate based on their experience.
At the end of the day, how long does powder coating take to dry? It all depends on a variety of factors, but with a little patience and the right conditions you should be able to get your items looking great in no time. For even more information on powder coating, check out Tomburn.
