Features Of Allnex ADDITOL AQ-1680 Alkali swellable thickener

  1. High-efficiency rheology control in waterborne systems via alkali-induced swelling.

  2. Excellent compatibility with acrylic, styrene-acrylic, and vinyl acetate-based emulsions.

  3. Provides outstanding sag resistance and brush/roller drag reduction in architectural coatings.

  4. Enables low-shear viscosity build with minimal impact on high-shear flow and spray atomization.

  5. Stable performance across a broad pH range (pH 8.5–10.5) without gelation or viscosity drift.

Typical Applications Of Allnex ADDITOL AQ-1680 Alkali swellable thickener

  1. Interior and exterior architectural wall paints (flat to semi-gloss).

  2. Waterborne primers and undercoats for wood and drywall substrates.

  3. Textured decorative coatings and elastomeric wall systems.

  4. Industrial maintenance coatings for metal and concrete surfaces.
