In addition, latexes that are co-stabilized with Natrosol hydroxyethylcellulose exhibit pseudoplastic rheology and excellent flow and leveling.
Latexes stabilized with Natrosol are widely used in paints and coatings, adhesives, and construction materials.
Monomer selection controls the degree of grafting. With vinyl acetate, the grafting tendency is low enough to achieve desired stability. In contrast, the high grafting tendency of acrylic monomers can cause instability or coagulation. In vinyl-acrylic latexes, the acrylic content should be kept below 30%.
In all-acrylic or high acrylic content latexes, grafting can be controlled through special processing techniques.
Natrosol 250 LR and GR are designed for use in emulsion polymerization.
