This olive sample panel is a visual reference for finish quality when cleaning metal before powder coating is performed correctly. Effective preparation typically includes:
Degrease/Soil removal: alkaline or solvent cleaning to remove oils, cutting fluids, and fingerprints.
Rinse: fresh water rinse to eliminate residues.
Surface prep: mechanical (blast/scotch-brite) and/or chemical etch to open the surface and improve anchor profile.
Conversion coating: iron/zirconium/phosphate to enhance adhesion and corrosion resistance.
Final DI rinse & drying/outgassing: prevents water marks, fisheyes, blisters, and other defects.
With clean substrate and controlled film build and cure, coatings exhibit a uniform matte texture, stable color, and long-term durability on steel or aluminum parts. The minimalist panel—bearing only the embossed BLUETEE logo—keeps attention on color accuracy and surface quality for specification, QC training, and blog illustration.
