Provided is a method for manufacturing a laminated rubber hose that includes a first layer and a second layer laminated on an outer surface of the first layer, the first layer containing a thermosetting resin in an amount of 4.5 parts by mass or less relative to 100 parts by mass of a rubber component, the method including laminating the second layer on the outer surface of the first layer with the outer surface of the first layer maintained at a temperature range of 65 C. or more and 105 C. or less.

The present invention is directed to film-forming compositions comprising: a) a non-chlorinated, linear polyolefin polymer comprising 0.5 to 10 percent by weight residues of an ethylenically unsaturated anhydride or acid; b) an aminoplast; and c) a component comprising: i) at least one non-chlorinated hydrocarbon having at least 18 carbon atoms and optionally aromatic groups and/or oxygen heteroatoms; and/or ii) an alkyd resin. The present invention is also drawn to methods of improving fuel resistance of a coated article, comprising: (1) applying the film-forming composition to a substrate to form a coated substrate; (2) optionally subjecting the coated substrate to a temperature for a time sufficient to cure the film-forming composition; (3) applying at least one curable film-forming composition to the coated substrate to form a multi-layer coated substrate; and (4) subjecting the multi-layer coated substrate to a temperature and for a time sufficient to cure all of the film-forming compositions.

This invention relates generally to vulcanization compounds and relates more specifically to vulcanization compositions with reduced allergenic potential that include accelerator compositions for vulcanizing elastomeric articles. Vulcanization compositions are disclosed that include a single fugitive dihydrocarbyl xanthogen polysulfide accelerator and a single aldehyde-aniline condensate accelerator.

An elastomeric article having a rubber component comprising polyisoprene and an aldehyde aniline condensate, the elastomeric article having less than 1 ppm diisopropyl xanthogen polysulfide residue.

Disclosed is a method of coating an elastomeric article including providing an elastomeric article having a first polymer latex, and coating the elastomeric article with a coating composition having a latex dispersion, the latex dispersion having polyisoprene and a vulcanization composition having a source of sulfur, at least one fugitive dihydrocarbyl xanthogen polysulfide accelerator, at least one aldehyde-aniline condensate, and a metal oxide, and a second polymer latex selected from the group consisting of natural rubber, polyurethane, polybutadiene, polychloroprene, nitrile rubber, block copolymers of styrene and butadiene, block copolymers of styrene and isoprene, and synthetic polyisoprene, and water.

Covalent network polymers that include one or more of a cure rate modifying (CRM) additive, a tack modifying additive, a flame retardant additive, a physical additive, and a viscosity modifying additive allow the viscosity, pot life, tackiness and safety of chemical mixtures and products to be tailored without sacrificing the mechanical properties or reprocessability of the final vitrimers. Use of additives also enables previously infeasible manufacturing techniques.
