Applications: hard coating is applied to improve the wettability and permeability and spreading properties of the substrate. Better coatings and inks to reduce static and dynamic surface tension. Does not affect the re-coating. Increase water-soluble coating of polyethylene, polypropylene, high smoothness, wettability leveling low surface energy material. Oil solve coating due to oil or surfactant-induced shrinkage, etc. * crater disease. Improve water-based varnish oiled speed. For improving the wettability of reducing the amount of organic solvent, to improve the printing properties. Typical properties: Parameter Unit Value Appearance colorless transparent liquid Viscosity 25 degrees m㎡ / s 60 Closed Cup C> effective component content 110% 100 HLB-EO 11.5 cloud point (1% water) ℃ <10 Application Methods: ink formulations, typically added in the range of 5211 0.1% -0.6% by weight. By balancing and dynamic surface tension of aqueous solutions of comparison, 5211 to enable the system to reduce the surface tension of the British 20.5--25 value. Aqueous system has a better leveling effect. Adding to be added directly or after dilution dispersed evenly in order to avoid foaming.
