Coating quality is half determined by the coating itself, and half by how well the surface was prepared.
Too many factories focus entirely on "what paint to use" while ignoring "what was done before painting." The result: peeling, fisheyes, failed salt spray tests, customer returns. The problem looks like it is in the coating — but the root cause is surface treatment.
Pre-Treatment — The "Invisible Process" That Determines Coating Fate
Coating pre-treatment is the foundational core process before metal spraying. It directly determines coating adhesion and anti-corrosion lifespan.
GEOOMET's pre-treatment process:
Pre-degreasing — removes most surface oil from workpieces
Main degreasing — deep cleaning of residual grease
Multi-stage rinsing — thorough removal of dust and chemical residues
Anti-rust film formation — generates a dense conversion film on the metal surface
Thermal curing — cures the film layer, ensuring subsequent coatings adhere firmly
When these five steps are done right, the paint film locks onto the substrate, eliminating fisheyes and peeling from the source. Anti-rust and salt spray performance for brake discs, wheel hubs, and other auto parts jumps to the next level.
Coating Materials: Good Coatings Need Good Ingredients
GEOOMET does not just build equipment — we supply high-quality coating materials:
Dacromet / Geomet coatings: Chromium-free zinc-aluminum coatings with exceptional corrosion resistance, widely used in automotive fasteners and braking systems
Chromium-free water-based zinc-aluminum coatings: The environmentally friendly alternative, matching traditional Geomet performance
High-performance water-based coatings: Including single-component and dual-component epoxy, as well as single-component acrylic coatings, suited for different application requirements
Materials, equipment, and process as one integrated system — something neither a pure equipment supplier nor a pure coating supplier can easily offer.
