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)
