The problem
What happens every day without the right product
Paint won't stick
On untreated metal, coatings flake and peel quickly.
Corrosion under the coating
Without phosphating, moisture works under the paint and the part degrades from inside.
Inconsistent quality
Improvised pre-treatments give different results from batch to batch.
The solution
Zinc phosphating: the right base for coating
The treatment builds a zinc phosphate layer that anchors paint to metal: superior adhesion, corrosion protection, repeatable results.
- Uniform anchor layer for paints and powder coating
- Standardized bath parameters: same result for every batch
- Improves salt-spray resistance
