Trusted Partner for Glove Offline Polymer Coating

Offline polymer coating is a crucial finishing process in glove manufacturing that adds a polymer layer to gloves after they have been fully formed and cured. Unlike online polymer coating, which is applied during production, offline polymer coating is used as a separate step once the glove has been stripped from the mold and vulcanized. This process significantly enhances the gloves’ usability, comfort, and barrier properties, making them ideal for a wide range of applications.

During the offline polymer coating method, gloves are either dipped or sprayed with a coating solution of polymer, usually on the inside (donning) side or the outside. This polymer coating lowers tackiness, makes the donning process easier, and enhances the overall performance of the glove, such as its barrier ability, comfort, etc. Polymers made of polyurethane and modified acrylic copolymer are usually used. A surface promoter, like sodium chloride or calcium nitrate, is commonly included to increase the amount of polymer absorbed on the glove surface, as well as to provide a smooth, non-yellowed finish. Following the application, the gloves are cured or dried to fix the polymer coating.

Offline polymer coating is one of the environmentally friendly methods for reducing powder use and eliminating the risk of exposing users to latex proteins, making it a suitable choice for powder-free nitrile (NBR) and natural rubber (NR) gloves. The coating enhances the properties of the gloves on the surface, making them very comfortable for users and allowing for easy wear.
