IX. Precautions
1. Paint and thinner should be sealed and stored in a cool place, fireproof, leak-proof, sun-proof, high-temperature resistant, and kept away from fire sources.
2. The storage period for paint is one year. Please ensure it is used within one year to avoid affecting quality.
3. After opening the paint can, stir thoroughly and evenly. Mix any residue from the bottom of the can into the mixing tank to prevent pigment settling and color difference.
4. After diluting the paint, use 200 mesh screen filter. Sprayed workpieces should be placed in a dust-free environment for 5-10 minutes before placing them into the oven.
