Protective metal surface treatments engineering robust barriers against severe atmospheric corrosion, high-temperature oxidation up to 650°C, and heavy mechanical abrasive wear.
Heavy-duty barrier coating providing superior salt spray and chemical corrosion protection.
Ceramic-reinforced protective coating maintaining integrity under continuous high temperatures.
Ultra-hard surface treatment engineered to resist abrasion, scratching, and chemical wear.
Engineering walkthrough demonstrating how Chemtech specialty materials prevent defects and optimize production yields at each stage.
Stage 01 • Surface Prep
Substrate metal is degreased and abrasive blasted to Near-White Metal (SSPC-SP 10 / NACE No. 2) with a uniform 50–75 µm anchor profile.
Why it matters: Eliminating mill scale, rust, and surface contaminants ensures maximum chemical crosslinking and prevents underfilm blistering.
Stage 02 • Anti-Corrosion
High-solids passivating barrier primer is applied via airless spray, sealing substrate micro-crevices and passivating steel against oxidation.
Why it matters: Exceeds 1,200+ hours in ASTM B117 salt spray exposure without blister formation or undercut creep.
Stage 03 • Thermal Shield
Modified silicone-ceramic matrix is applied across thermal zones, engineered for continuous operation up to 650°C (1200°F).
Why it matters: Prevents metal decarburization, thermal oxidation scaling, and flaking under relentless thermal quenching cycles.
Stage 04 • Hard Armor
Ultra-hard wear-resistant topcoat is cured, providing Shore D 85+ surface hardness and high Taber abrasion resistance.
Why it matters: Shields high-value valves, machine shafts, and tooling dies from abrasive slurries, gouging, and mechanical fretting.
Stage 05 • Validation
Finished component undergoes dry film thickness (DFT) verification, cross-hatch adhesion testing, and holiday porosity spark inspection.
Why it matters: Guarantees 100% pinhole-free coverage for long-term asset life in offshore, chemical plant, and furnace environments.
