Sulfonation of clear plastic parts confers excellent anti-fog properties.
Sulfonated plastic parts lead to enhanced dissipation of static electricity, relative to untreated parts.
Sulfonation of plastic in many cases increase adhesion, of top coats, paint or metal to plastics.
Sulfonation provides an alternative to chromium VI pretreatment of ABS and PC/ABS and is also effective on a broad spectrum of other polymers.
Many polymers have hydrophobic surfaces, but often a hydrophilic surface is desired for various applications where there is a need for a wettable or lubricious surface.
