ROKAnol® L30 is a non-ionic surfactant used mainly as an emulsifier in the emulsion polymerization process. The product comes in the form of white wax with a solidification point of approximately 45°C. At the synthesis stage, ROKAnol® L30 emulsifies the monomer and stabilizes the particles of the resulting polymer, preventing coagulation of the emerging dispersion.
The high efficiency of the agent during a reaction is obtained in combination with a suitable anionic surfactant, in particular SULFOROKAnol L430/1, SULFOROKAnol L725/1 or SULFOROKAnol L1230/1. The combination with anionic agents allows perfect control of the dispersion particle size.
After the polymerization reaction, ROKAnol® L30 demonstrates excellent dispersion stabilizing properties. The high content of ethylene oxide in the product (30 moles EO) provides significant resistance to electrolytes and greatly improves the resistance of the dispersion to repeated freezing and thawing.
ROKAnol® L30 is used in the production of most polymer-acrylic and styrene-acrylic dispersions as well as vinyl acetate homo- and copolymers (including VAE dispersions). The recommended product concentration of the entire formulation is 0.5%-3% by weight.
