Glasurit® Primer Filler, black
285-790
 
G / PF

Application:

 

Primer filler with

Properties:

 

excellent spray ability, sagging resistance and filling properties
wet and dry sanding properties

Remarks:

 
  • 285-790 can be mixed with Glasurit Primer Filler 285-730 to achieve different grey shades
  • 285-790 can be mixed with Glasurit 523-15 Racing Additive to reduce the drying time (to 15 min at 60°C, 1.5h at 20°C or 6 min with short-wave infrared). Please observe that the mixture has a potlife of only 20 min at 20°C and can only be used for applying film thicknesses of 50-70 μm.
