Questions
Frequently asked
Why is surface preparation important for powder coating?
Contamination, oxide, scale and poor pretreatment can reduce adhesion and corrosion performance even when the powder itself is high quality.
Can old powder coating be recoated?
Sometimes, but the existing coating condition, adhesion, compatibility and required finish should be evaluated. Stripping back to a suitable substrate may be necessary.
