Abstract
Methods of forming a chemical barrier against the transmission of disease-causing microbes and other harmful agents through a membrane such as latex. In the principal method, a mold or former is coded with a coagulant, which is dried, and then the former is dipped into liquid latex, which is allowed to gel, and then the former is dipped into a solution containing the biocide, and then the former is dipped again into the liquid latex, after which the entire coating on the former is cured. Alternatively, the biocide may be sprayed or otherwise applied onto the gelled latex.
