Pigment Dispersants
This polymer functions as an effective dispersant for pigments, aiding in their uniform distribution within various formulations. Its hydrophobic nature contributes to compatibility with non-polar systems.
Paper Sizing Agent
Utilised in the paper industry, it acts as a sizing agent to control the absorption of liquids into the paper. This improves the paper's resistance to ink and water.
Film Leveling Aid
In film formulations, it serves as a leveling agent, promoting a smooth and uniform surface finish. This enhances the aesthetic and functional properties of the film.
Embrittling Agent
It can be employed as an embrittling agent in certain applications, such as shampoos, to modify the texture and properties of the final product. It also functions as an anti-resoil agent.
