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, allowing for precise tint, shade, and hue control. The chemistry of both the binder and the specific product in which it is integrated may also influence the consistency and viscosity, sometimes inducing 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, affecting properties like saturation and blend quality. Similarly, a universal binder lacking specific functionality in any of these chemistries can also lead to a plasticizing effect, impacting the final paint or dye application.

This plasticizing influence is critical to the overall behavior of the resin system, demanding careful consideration during formulation and processing to customize and attain the desired material characteristics without unintended consequences. A highly concentrated colourant with carefully balanced additives can mix more effectively and outperform one with a lower pigment concentration, as 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 effects, compatibility issues, and a variety of other performance-related challenges.
