The following thinner is recommended for PPG SigmaCover 350:
- PPG Thinner 91-92 for global
- 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
- Adding too much thinner results in reduced sag resistance
- Thinner should be added after mixing the components
Please refer to the product Data Sheet for further details regarding the required volume of thinner.
