MC390 is a 2K UHS clearcoat (VOC < 350 g/l) formulated with “Air-Tech” technology. The fast air drying speed allows significant energy savings as well as high levels of productivity thanks to a very rapid working process.
The very low emission of gas combustion during the drying step along with the low product solvent emission (VOC <350 g/l) ensure a high level of environment sustainability.
MC390 Clearcoat for two-coat mica, metallic and solid finishes, conceived for all types of repairs in the car body shop; its use is especially recommended as part of the AIR-Tech Process.
Application
By conventional high transfer spray and HVLP.
Setup
Spray viscosity at 20°C: 13-15" DIN4 Ø
Air cap: 1.2 mm (recommended)
Air pressure: as recommended by the producer
Dry film thickness: 45-60 µ
Time of use at 20°C and 50% R.H.: 30 min.
Theoretical coverage: 9,4 m² for 1 kg mixture at 40 µ; 9,6 m² for 1 l mixture at 50 µ
Drying time
Air drying at 20°C and R.H. 50% (High humidity makes the product drying faster.) The drying continues for the following 48 hours.
- Dust-free 15 min.
- Handling 45 min.
- Polishing 1,5 hours
- Through-drying 6 hours
Low bake at 40-50°C: 10-15 min.
IR lamps: not recommended.
Important about SUBSTRATE PREPARATION. Surfaces already painted only with the following matt basecoats:
- HYDROFAN HE Basecoat activated at 7% with HH981 HYDROFAN BC EASY ACTIVATOR (see relevant TDS)
See the technical datasheet for more.
- Excellent air drying speed
- Important cost reduction in the drying process (low energy consumption)
- High productivity and profitability (also low baking is possible)
- Very good flow and gloss
- Very good film hardness and good surface sliding.
- High execution speed of the repair process; the product can be polished after just over 1 hour
- Low environmental impact, due to very low VOC emissions <350 g/l and no baking
- Industries: Car Refinish
- Brand: Lechler
