Formulation development with Kollicoat Smartseal: Impact of plasticizers

How can plasticizers impact the functionality of film-coating latex-based dispersion?

When formulating a film coating, plasticizers are often required to increase polymer chain mobility, improve mechanical properties, such as elasticity and cracking resistance, and reduce the minimum film forming temperature.

The plasticizer selection and concentration are based on the plasticizing effect, similar physicochemical characteristics, desired flexibility, and compatibility with all formulation components.

However, particular attention should be paid to latex dispersions when adding this ingredient. Plasticizers can interfere with the dispersion’s stability by changing the electrostatic repulsion between particles, causing coagulation and a lack of polymer functionality.
