CytoN 561

CytoN 561 is a non-reactive, ethylene glycol based polymeric surfactant compatible with most polar solvent (alcohol) based inks, coatings, resists and emulsions. 561 is non-ionic and provides low surface tension in polar coating systems. This is an excellent wetting, leveling and spreading agent for a variety of waterborne, high-solids and radiation curable coatings. CytoN 561 may replace Capstone FS3100. CytoN 561 may also be an alternative for Fluorad FC-430, FC-4430, or FC-171.

Comparing CytoN 561 and 562: CytoN 560 series products have four pendant groups on a polypropylene glycol backbone. CytoN 561 has two active pendant groups and two polyethylene glycol groups. For CytoN 562 the ratio is one pendant group and three polyethylene glycol groups. Therefore, CytoN 561 has a slightly lower surface than CytoN 562.
Applications: CytoN 561 is used as an additive in architectural coatings, inks, floor polishes, waxes, high solids coatings, water reducible coatings, radiation curable coatings and photoresists. Recommended use level is between 0.05% and 1.0% active surfactant. However, use level can vary depending on the application and concentration of other additives and solvents in the formulation.
Regulatory: CytoN 561 is compliant with the chemical notification requirements of TSCA and REACH.
