Original title: Associative alkali swelling thickener - two commonly used thickeners for adhesives
At present, there are two kinds of thickeners commonly used in adhesives, namely traditional compound thickeners (external thickeners) and emerging associative alkali swelling thickeners (internal thickeners)
adhesive thickener
adhesive thickenerAdvantages of Adhesive Thickeners:
The composition of the adhesive thickener is alkali-soluble acrylate emulsion resin, and the thickening of the associative thickener is divided into two aspects
One aspect is that the macromolecule dissolved in water increases the viscosity of the water; the second aspect is that the associative alkali solvent thickener associates the latex particles and the powder particles to form a network structure to reduce the fluidity of the system and make the adhesion.
Another advantage of the associative alkali swell thickener is that its composition is the same as that of the acrylic emulsion for adhesives.

It is not scientific to use the two thickeners together.
