    Application test

    We tested the comprehensive performance of KEPERSURF®-159N and B-358N in Alkyd, hydroxyl acrylic acid ,Polyester/amino systems.

    Compare items and methods

    1.Compatibility: Add 0.1%, 0.3%, 1% and 2% additives to be tested in alkyd PU system and hydroxypropyl PU system respectively, and observe the transparency after adding different amounts.
    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.Recoatability:After adding additives to the required test system, spray the dry film after secondary spraying to test the adhesion.
