Surface modifiers

Surface modifiers are added to formulations to modify the surface characteristics of polymer systems. XIBOND® surface modifiers can migrate to the polymer’s surface, where their functional groups will increase its polarity and reactivity, optimizing it for secondary operations.

Specific secondary operations such as printing, painting and gluing require a certain surface chemistry. The addition of surface modifiers can enhance the surface characteristics by bringing functional groups to the surface of a polymer system. The migration of the surface modifiers influences the surface tension, resulting in a modified surface chemistry. These reactive groups can optimize interfacial tension, thereby facilitating adhesion between two materials in a co-extrusion or multilayer process.

The addition of XIBOND® Surface Modifiers influences the polarity of the surface due to the presence of polar maleic anhydride (MA) functionality. This increases the surface tension of polymer matrices, especially for styrenics such as ABS and PS. This can be beneficial to different secondary operations such as gluing, painting and multilayer systems.
