Anti-cratering & Dispersing Agent (Rheoflo...

Description Rheoflow DXW-4040 is based on a water soluble high molecular weight polymer. It has execllent anticratering and dispersing power with good levelling properties. It can be added in the water based coatings and cationic ED-paints etc.. Composition Specialized water soluble high molecular weight polymer Properties Active ingredients 40±2% Viscosity(23°C) 9,000~20,000cps Appearance yellow or amber, clear liquid Density(20°C) 1.05±0.02g/cm3 Flashpoint Min 100°C Meq-acid 120-150 Advantages Excellent anticratering power on the coated film Excellent wetting and dispersing effect on filler and pigments. Good flow and levelling properties. Good film appearance and recoatable properties. Applications ED-paints - Anionic and cationic coatings Water based coatings. - Urethane, acrylic, epoxy, polyester, alkyd etc. Water based any other coatings and inks oxies. Recommended Amounts and Incorporation Methods In coating systems, Rheoflow DXW-4040 can be added 2~8% of delivery form on the resin solid. Usually it is added the CED bath directly under stirring. And also it can be added to the resin before the dispersion. Storage Water containing resins may freeze at temperatures below 0°C or become inhomogenous. Rheoflow DXW-4040 does not suffer any damage from it, the necessary regeneration depends however on a warmth treatment at 40°C~50°C while stirring. Therefore, such products should be stored away from frost. At temperatures till 30°C the storage stability of the originally packed product is at least 3 months.
