 Make sure the substracts in well prepare
 Lacquer must be well mix with proper thinner and check
viscosity , when hardener in use, make sure its well mix and
be sure of pot-life
 Make sure the application equipment is properly clean and
right nozzle of spray gun and output of lacquer paints be
adjusted.

12. Terms use in mixture
1. Single pack: just dilute with thinner
2. Ready to use: just spray (RTU)
3. Atmosphere cure or self crosslink : react with oxygen
and crosslink
4. Two pack : part A & part B (hardener pot-life applied
PU, NC)
5. Three pack : part A (lacquer); B (mek peroxide); C
(cobalt-diluene strene monomer)
6. U.V cure by UV lamp
7. Open grain and full grain cover; semi open grain.

13. Recommended viscosity for different
application
 Viscosity (hand spray recommended) 12 second to 13
second (Ford cup 4) ;
 Viscosity airless spray – 18 second (Ford cup 4)
 Viscosity curtain coater & rainbow – 33 second (Ford cup 4)
 Disk electrostatic – 9 second
 Roller coater – 2 minute
 Dipping – 10 second

14. Thinner is very important
1. To achieve better dilution.
2. Too slow drying cause stacking problem. Too fast drying causing flow
problem.
3. Good electrostatic charge
4. Blushing
5. Orange peel
6. Fast dry (pin hole) in two pack system
7. Using recycle thinner may cause many problem
 Mixture of different kind of coatings in inter coat
 PU sealer & NC top (ok)
 NC sealer & PU top (not allow)
 AC sealer & PU top (not allow)
 PU sealer & AC top (not allow)
 PE sealer & PU top (ok)
