The following thinner is recommended for PPG SigmaCover 350:


  • The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity

  • Thinner should be added after mixing the components

Please refer to the product Data Sheet for further details regarding the required volume of thinner.
