Emulsion paint containing HEC components has the properties of fast dissolution, low foam, good thickening effect, good color expansion and more stability. Its nonionic nature helps to stabilize over a wide pH range and allows a wide formulation latitude.
A further advantage of some models is that the thickener is added to the water at the beginning of the pigment grind to control hydration.
High-viscosity grades are mainly developed for the production of water-soluble latex paints. And the dosage is smaller than other thickeners.
●Paper and Ink
HEC can be used as a polishing agent for paper and board and as a protective glue for inks. HEC has the advantage of being independent of paper size in printing. And can be used for printing of high-quality images. At the same time, because HEC has low surface permeability and strong gloss, it can also reduce costs.
It can also be applied to any size paper or cardboard printing or calendar printing. In paper sizing, its usual dosage is 0.5 ~ 2.0g/㎡.
HEC can increase the water retention performance in the color of the paint, especially for the paint with a high proportion of latex.
In the papermaking process, HEC has other superior properties. Including compatibility with most gums, resins and inorganic salts, instant solubility, low foam, low oxygen consumption and the ability to form a smooth surface film.
In ink manufacturing, HEC is used in the production of water-based copying inks, which can dry quickly and have good color diffusion without sticking.
