Glasurit® Racing Additive
523-15
 
G / Z

Application:

 

Drying accelerator for Glasurit standard clears (VOC-compliant and non-VOC-compliant), 22 Line, 22 Line VOC, 22 VOC MC600 and 285- HS-Primerfiller / Filler

Properties:

 
  • Reduction of drying times
  • Improves surface drying and curing performance as well as tape resistance

Properties:

 

No add of 523-15 Racing Additive in 285- Primerfiller / Filler at temperatures > 25°C possible, due to too short potlife
