Short answer: Coating defects on metal — pinholing, cissing, peeling, orange peel and rust bleed — almost always trace back to surface preparation, film thickness or application; they are prevented by cleaning, correct blasting profile and controlled application.
At a Glance
Why Coatings Fail
Nine times out of ten the root cause is the surface: oil, oxide or low roughness lets the film let go. Prep discipline lives in Metal Degreasing Guide e Metal Coating Thickness Guide; selection with Anodizing Vs Powder Coating e Thermal Spray Coating Guide.
Reading the Defects
Pinholing means trapped gas or too-thin film; cissing means silicone or oil contamination; peeling means poor adhesion profile; orange peel means wrong spray/viscosity; rust bleed means substrate was not fully cleaned. All tie to Metal Surface Treatment Guide e How To Prevent Metal Rust.
Control, QA & Supply
Blast to spec, measure DFT, degrease and bake out gas; add Metal Corrosion Inhibitor Guide in the primer, verify via Metal Ndt Guide and document per Mill Test Certificate Guide. HXSCO supplies pre-treated, coat-ready stock.
