1 Coating shall be carried on at ambient temperature between 0℃ and 35℃. Minding weather changes. Under rainy, foggy, snowy days and relative humidity ≥85%, direct summer sunlight the application is prohibited. The substrate must be dry, otherwise it will bubble

2 Adjust the viscosity with our exempt solvents. Thinners from other companies or other brands are not allowed to use, otherwise we will not be held responsible for any problems.

3 Polyurethane coating belongs to reactive paint. Before application, it must be fully stirred to evenness, accurately proportioned according to instruction, ready for use after standing and curing for 10min. If the temperature is low, the curing time can be appropriately extended. The prepared coating must be used up within 2 hours, to avoid waste due to cementation. Do not pour the unused though prepared paint back into the can.

4. After coating is taken out for use, the cover of the packaging can must be tightly sealed. Air leakage shall be avoided to prevent paint deterioration or failure. Avoid long-time inhalation of solvent vapor and fog. The workplace shall enhance ventilation.
