Surface modifiers are added to formulations to modify the surface characteristics of polymer systems. XIBOND™ can migrate to the surface where its functional groups will increase the polarity and reactivity of polymers 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, thus resulting in a modified surface chemistry. Furthermore, these reactive groups can optimize the interfacial tension and by this the 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 a benefit in different secondary operations such as gluing, painting and multilayer systems.
