Hydropalat 875 Anionic compound Cognis Surfactants ADHESIVE >> Water-based Anionic compound. HYDROPALAT® 875 is a very good wetting agent with only a medium tendency of foam formation in aqueous solutions or in polymer dispersions. The relatively low critical micelle concentration of approximately 1 g active substance/l and the strong reduction in surface tension of aqueous solutions, even when using low concentrations, make HYDROPALAT® 875 an ideal surface active agent. HYDROPALAT® 875 is just slightly water-soluble. The water solubility may be increased by the addition of a small amount of a solubilizer allowing solubility of up to 80 % to be achieved. Diluting HYDROPALAT® 875 with water is possible up to a certain extent, but liquid-crystalline gel type phases may occur in the region of approximately 50 % active substance. HYDROPALAT® 875 is used as a wetting agent in aqueous coatings, printing inks and related systems. On account of its good wetting properties it is particularly suitable for difficult-to-wet substrates such as plastics and metal surfaces, cellulose film, aluminium and plastic foils, silicone treated papers or glass. HYDROPALAT® 875 can be used to optimise the compatibility (colouracceptance) of aqueous pigment concentrates in different coatings. HYDROPALAT® 875 can be incorparated either into the pigment concentrate or directly into the base paint. It can also be used as "Post additive". HYDROPALAT® 875 may be used as an emulsifier for the emulsion polymerization of practically all types of monomers. The polymer dispersions stabilized by means of HYDROPALAT® 875 excell by their very good wetting properties. If outstanding wetting properties of a dispersion must be combined with high mechanical stability, we recommend the use of HYDROPALAT® 875 together with our highly ethoxylated non-ionic surfactants of the Disponil LS, TA or NP type. Highly efficient anionic wetting agent. Possesses a medium tendency of foam formation in aqueous solutions or in polymer dispersions. Provides strong reduction in surface tension of aqueous solutions, even when using low concentrations. Suits for difficult-to-wet substrates such as plastics and metal surfaces, cellulose film, aluminium and plastic foils, silicone treated papers or glass. May be used as an emulsifier for the emulsion polymerization of practically all types of monomers.
