90 Line Glasurit® Basecoat
G / T



Metallic and solid-colour basecoat/clearcoat finishing. Wet-on-wet process with Glasurit 923- Clear.



Very good hiding power, high efficiency.

Water-thinnable, less than 10% organic solvents.


  • Mixing formulas with 90-M4 and mixing bases are available to cover the whole range of colours needed in automotive refinishing.
  • At rather high temperatures or when refinishing large surfaces, it is possible to replace 90-M4 by 90-M4 slow, while replacing 93-E3 Adjusting base by 93-E3 slow at the same time.
  • Mixtures will keep for up to 6 months when stored in plastic containers or cans coated inside.
  • Use of 93-IC 330 if recommended by car manufacturers (see Technical Information).
  • Flash-off times can be reduced significantly by using appropriate air blow equipment.
  • Flash-off time before application of 923- Clear: 2-3 min. (until surface is mat).
  • When using white colors with high spray viscosity the mixing ratio can be changed to 100 : 80.
