Original title: What is the difference between thickeners commonly used in water-based wood coatings and polyurethane associative thickeners?

Among the consumers of water-based wood paint, furniture factories and toy factories are the most important consumers

The types of thickeners are mainly divided into inorganic thickeners, cellulose thickeners, alkali-swellable thickeners and polyurethane associative thickeners

wood lacquer with thickener

The same type of thickener, the higher the thickening efficiency, the higher the viscosity of the paint liquid, and the better the storage stability

The polyurethane associative thickener achieves the thickening effect through the formation of micelles by part of the hydrophobic segment and the association of part of the hydrophobic segment with the particles of the solution

Application scenarios of wood lacquer

Spray construction:

The sample paint was diluted and used for spraying.

Leveling:

The leveling of the coating film will affect the final quality of the coating film, and the thickener has a great influence on the leveling of the coating film

Summarize:

Polyurethane associative thickeners have good sprayability and leveling properties, but these thickeners have poor performance in anti-settling of fillers with polar surfaces
