Title:
MOLD RELEASE AND ANTI-BLOCKING COATING FOR POWDER-FREE NATURAL OR SYNTHETIC RUBBER ARTICLES
Document Type and Number:
WIPO Patent Application WO2002068168
Kind Code:
A3
Abstract:
The present invention is directed to a release composition for molds and formers used in the production of natural and synthetic latex articles. The release coating contains a water-borne, high Tg polymer formed from at least one hydrophobic monomer and at least one hydrophilic monomer, where the Tg of the polymer is at least - 10 DEG C. One advantage of the release composition is that it is compatible with a coagulant solution used in the formation of latex gloves. Articles formed using the release coating have good anti-blocking properties.
