PU polymer coating for glove

PU Polymer coating  

All latex gloves, natural or synthetic, is tacky and sticky by nature on the surface. This stickiness provides the grip, which is an inherent property of dry rubber.

In the manufacture of gloves, a thin surface technology, the film becomes sticky after manufacture. This is overcome by applying a powder like modified absorbable corn starch to the glove.

Another method is via halogenation, where a light solution of chlorine is applied to the surface of the gloves for a short duration and then fully washed away. This is a treatment that smoothens the surface of the gloves.

A third method is to apply a thin coating of polymeric material-like polyurethane-based polymer. This polymer imparts a non sticky surface to the gloves as well as acting as a second layer. This method has been widely accepted in that not only the polymer layer acts to cut off the tackiness, but as a coating, it also acts as a barrier against direct contact with the main base material like latex or synthetic butadiene. For some users this may be an advantage if they are extra sensitive to certain materials.

The polyurethane coated gloves ordinarily have knit liner and are coated with polyurethane resin, so have a thin coated resin layer and feels comfortable when wearing. Besides, the gloves are oil-proofing, wearproof, and low-cost.
