VISIOMER Paper & Water

VISIOMER® - methacrylate monomers for water and paper applications

Application Areas



VISIOMER Flocculants

When it comes to wastewater clearing and sludge dewatering, high molecular weight polyelectrolytes are used alone or in combination with inorganic coagulants. They are active over a wider pH range than inorganic coagulants and produce smaller volumes of more concentrated, rapidly settling and more shear-stable precipitate. Cationic, non-ionic and anionic copolymers are used as well. Generally, cationic polymers are built from acrylamide and cationic methacrylate monomers, such as VISIOMER® TMAEMC and MAPTAC. These products can be customized by tweaking the amount of quaternized monomers incorporated into the polymer.

Paper Coatings


Coating is an important lever for improving paper quality. Key properties, such as print quality, surface protection and increased resistance can all be improved with specific coatings. Here, binders based on acrylic emulsions are commonly used. For more detailed informationn about emulsion, please also refer to the emulsion section.

Sizing Agents


Sizes are primarily used to make the paper more resistant to water and other liquids, and to control ink spread. Additional benefits are increased dry strength, less dusting, improved surface strength and enhanced smoothness. Cationic polymers used as surface sizes are often based on styrene acrylic emulsions. Besides our basic methacrylates VISIOMER® MMA, GMAA, n-BMA and i-BMA, the amino-functionalized methacrylates we propose – DMAPMA, VISIOMER® MADAME™, TMAEMC and MAPTAC – deliver key added value in these applications.

Retention Agents

VISIOMER Paper & Packaging Coatings

Copolymers containing amino methacrylates, such as VISIOMER® MADAME and DMAPMA, are suitable as retention agents in papermaking. Consisting predominantly of cationic polyelectrolytes, they improve retention in the draining of pulp during the paper making process. Their efficiency can be tuned across a wide spectrum via the molecular weight and content of amino groups. In (weakly acid) pulp suspensions, such polymers are present as cationic polyelectrolytes. Besides their role as retention agents, they ensure rapid suspension dewatering. The copolymers of our quaternized amino methacrylate monomers VISIOMER® TMAEMC and MAPTAC act as retention and dewatering agents as well. In their capacity as ‘genuine’ polyelectrolytes, they perform these duties in the acid as well as in neutral range.
