Product Description
Hydroxyethyl cellulose (HEC) is white or light yellow, odorless, non-toxic fibrous or powdery solid, soaked in raw cotton linters or refined pulp in 30% liquid alkali, and taken out after half an hour. Press until the ratio of alkaline water reaches 1: 2.8, and crush it. Then prepared by etherification reaction, it belongs to non-ionic soluble cellulose ethers. HEC is an important thickener in latex paints. Let's talk about how to use hydroxyethyl cellulose HEC in latex paints and precautions.
Equipped with mother liquor for standby: use HEC to equip the mother liquor with higher concentration before adding to the product.
The advantage of this method is that it has greater flexibility and can be added directly to the finished product, but it must be properly stored. This method does not use a high-shear stirrer, but only a stirrer with sufficient power to keep the HEC uniformly dispersed in the solution. Continue to stir until completely dissolved into a viscous solution. However, it must be noted that the mold inhibitor must be added to the mother liquor as soon as possible.
