ALLUVERSAL COLOURANT UHS

The Solution To Plasticizing Effect: Alluversal Colourant UHS

Colourants specifically formulated for use in multi-component resin systems such as epoxy, polyurethane, and polyaspartic are composed of pigments finely ground into a binder or vehicle. The chemistry of both the binder and the specific product in which it is integrated may induce a plasticizing effect.

For instance, if a colourant is formulated from an epoxy resin, it may produce a plasticizing effect when used in polyurethane or polyaspartic systems. This happens as the chemistry of the colourant interacts with the resin system’s matrix, altering its properties. Similarly, a universal binder lacking specific functionality in any of these chemistries can also lead to a plasticizing effect.

This plasticizing influence is critical to the overall behavior of the resin system, demanding careful consideration during formulation and processing to attain the desired material characteristics without unintended consequences. A highly concentrated colourant outperforms one with a lower pigment concentration because the high pigment concentration can replace the plasticizing effect in a film.

This, in turn, leads to improved physical properties, typically including higher glass transition temperatures (Tg), reduced risks of impaired adhesion, leaching, migration, tire staining effect, compatibility issues, and a variety of other performance-related challenges.
