HYDROPALAT WE 3475
HYDROPALAT WE 3475
HYDROPALAT® WE 3475 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 WE 3475 an ideal surface active agent.
This material 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 this wetting agent 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 WE 3475 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.
It can be used to optimize the compatibility (colour acceptance) of aqueous pigment concentrates in different coatings and can be incorporated either into the pigment concentrate or directly into the base paint. It can also be used as “Post additive”. It may be used as an emulsifier for the emulsion polymerization of practically all types of monomers. The polymer dispersions stabilized by means of HYDROPALAT WE 3475 excel by their very good wetting properties.
