2-pack HS Performance surfacer

Method of application: “spray”.
 

2-pack HS Performance surfacer

–  Application viscosity 4 mm, +20 °C, DIN 53211
Application viscosity 4 mm, gravity-feed spray gun “compliant” and “HVLP”.
 

2-pack HS Performance surfacer

Add 10-15% VHS Performance hardener at material temperature +20 °C.
–  If hardener is added, use measuring stick to mix.
 

2-pack HS Performance surfacer

–  Adjust spray nozzle following manufacturer's instructions to 1.4-1.8 mm for “compliancy”.
–  Adjust spray nozzle following manufacturer's instructions to 1.7-1.9 mm for “HVLP”.
–  Adjust spray pressure following manufacturer's instructions to 1.5-2.0 bar for “compliancy”.
–  Adjust atomising pressure following manufacturer's instructions to 0.7 bar for “HVLP”.
 

2-pack HS Performance surfacer

–  One to three spray coats (with intermediate flash-off time) are necessary to attain the recommended dry-film thickness of 60-250 µm.
 

2-pack HS Performance surfacer

Drying
The material can be sanded after 2-3 hours (film thickness of 60-150 µm and air drying at +20 °C ambient temperature).
If a film thickness of 150-250 µm was applied, allow the material to dry overnight before sanding.
 

2-pack HS Performance surfacer

Final flash-off time with force drying is at least 5-15 minutes.
 

2-pack HS Performance surfacer

Force drying at +60 °C material temperature up to 60-150 µm, 15-20 minutes, and 150-250 µm 20-25 minutes.
 

2-pack HS Performance surfacer

Final flash-off time with infrared drying is at least 5-10 minutes.
 

2-pack HS Performance surfacer

Infrared drying (depending on film thickness): short-wave radiant heater, 10 minutes (dry 2 minutes at 50% power and 8 minutes at 100% power).
 

2-pack HS Performance surfacer

Further steps
–  Dry sand using orbital sander with P500 to P600-grain sandpaper and dust collector.
 

2-pack HS Performance surfacer

–  Wet sand with P800 to P1000-grain sandpaper.
 

2-pack HS Performance surfacer

Recoating
Recoat with:
  Waterborne base coat and 2-pack HS clear coat
  2-pack HS top coat
 

2-pack HS Performance surfacer

Special notes
Elasticization for rigid and semi-rigid plastics:
  First mix the base material with 15% elastic additive -ALZ 011 001-. Mixing ratio 4:1 with VHS Performance hardeners and 10% thinner.
  Any substrate defects can be treated with 2-pack polyester filler. After drying and intermediate sanding, isolate the filler patches with 2-pack HS Performance surfacer.
  When isolating certain spots - even on problem substrates - the best results are achieved with a medium film thickness of 80-120 μm in 2 coats, after either air drying overnight, force drying or infrared drying. With problem substrates, careful pretreatment is imperative, and the surfacer must be applied to the entire surface.
  For isolating thermoplastic paint, 2-pack HS Vario surfacer -LGF 786 004 A4-, grey is recommended.
  A minimum temperature of +15°C is recommended for air drying.

Personal protective equipment:
  Adhere to the safety data sheet.
  Wear personal protective equipment during application.
