CHEMICAL- RESISTANT BASE COAT
SOLVENT BASE
Zinc-Aluminium Flakes | Nano-Carbon Crystals
Our solvent-based base coat combines zinc and aluminium flakes
with Corundum and nano-carbon crystals to create a thin, ultra-protective anti-corrosion film.

Chemical Resistance: Industrial-grade resilience against aggressive compounds.
Automotive Fluids: Resists fuels, oils, and brake fluids without degradation.

TECHNICAL APPLICATION
APPLICATION
PRECISION
Our non-electrolytic process ensures consistent application for high-strength fasteners and complex components.
- SUBMERSION- Components are submerged in a precision coating solution containing zinc and aluminum flakes, ensuring 100% even coverage
- CURING PROCESS- Parts are cured in controlled ovens, creating a molecular bond that shields against the harshest environmental conditions.
- SUPERIOR SHIELD- The final layer provides unmatched corrosion resistance without the risk of hydrogen embrittlement.
Deployment Methods- Flexible application techniques optimized for your production volume.
Dip-Spin | Rack Dip-Spin | Spray Application

Safety Standard- Zero risk of Hydrogen Embrittlement,unlike traditional electrolytic methods.
