    Product overview

    KEPERDISP®-604 make the pigments controlled flocculation, can reduce flow hanging and settling.. Provides moderate thixotropy without affecting leveling.

    Physical data

    1. Effective ingredient: Polyether siloxane copolymer

    2.Content:  100%

    3.Solvent:   NO

    Product features

    1.Excellent wettability, unstable bubbles also have good wetting ability for low surface tension substrate.  
    2.Better anti-shrinkage performance, Excellent spreadability and permeability. 
    3.Excellent recoating properties. can be used in water-based (alkaline environment), solvent-based, UV systems. 

    Application test

    We tested the comprehensive performance of KEPERSURF®-127 and T-270 in water-based acrylic baking paint system.

    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. Dry film levelling: Spray normally and observe the surface levelling of the paint film after complete drying.
    3.Wetting property : Add 0.2% additives in the alkyd PU system, spray plate after thinning to observe the wetting property;
    4.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.
    5.Recoatability:After adding additives to the required test system, spray the dry film after secondary spraying to test the adhesion.
