Compare items and methods
2. Wet film levelling: test the spray plate after thinning, and observe the surface levelling after spraying.
3. Dry film levelling: Spray normally and observe the surface levelling of the paint film after complete drying.
4. Wetting property : Add 0.2% additives in the alkyd PU system, spray plate after thinning to observe the wetting property;
5. Unstable bubble performance: After adding the tested additives to the paint and diluting it, fill the same amount of paint with a test tube and observe the number of bubbles and elimination time.
6. Recoatability:After adding additives to the required test system, spray the dry film after secondary spraying to test the adhesion.
