Fuctional Coatings – Henkel Vietnam
Functional Coating Overview
Why we need pre-treatment?
Prior to painting, substrates often are:
Dirty and full of dust
Covered in oil (processing oils, temporary
corrosion protection)
Corroded (rust, welding scale)
Pre-Treatment provides:
Cleaning
Paint adhesion
Corrosion protection

Nanoceramic Pre-Treatment Technology
More Savings, Fewer Steps
Improve quality through complexity
reduction (simple process control).
Increase productivity by 10% or more
by reducing maintenance time (no
sludge)
Multi-metal conversion (iron, steel,
aluminum…).
Minimize environmental impact.
Save money by reducing process costs
up to 50% (energy, time, waste, water,
chemical)
