Ottopol 25-30 is the ammonia-cut version of Ottopol 25-50E. This solution polymer has good adhesion to non-porous surfaces. Belonging to the Ottopol 25 Series, it is specifically designed for use as a grinding and letdown vehicle for water-based rotogravure and flexographic inks. It provides high gloss and excellent press stability. Ink and coating makers will benefit from the versatility of this series as a sole binder or component of high-gloss inks and overlay varnishes. These polymers are derived from the same monomer composition, and the dry resin is identical throughout the series.
Function: Binder, Grinding Aid
Chemical Family: Acrylics & Acrylates
Compatible Polymers & Resins: Polystyrenes (PS), Polyesters, Polyvinyl Chloride (PVC), Cellulose & Cellulosics

Ottopol 25-30 Features & Benefits
Product Highlights
Superior Printing Qualities
- Ottopol 25 Series’ unique characteristics impart excellent flow and leveling to inks and coatings, making gravure print quality possible that could only be attained with solvent systems in the past. The viscosity curve of this resin is relatively flat and shows a very low degree of thixotropy. The result is superior printing quality.
Good Pigment Wetting
- High industry standards are met when Ottopol 25 Series is used as a dispersion stabilizer, or purely for wetting purposes. Optimum color development is achieved with a large variety of pigments.
Excellent Gloss
- The rheological properties of Ottopol 25 solutions contribute to high gloss, while the use of maximum amounts of alcohol will increase the gloss of this resin.
Excellent Adhesion to Substrates
- On PVC, Polyester, Polystyrene, and Coated Cellophane, this series of polymers provide excellent adhesion.
