A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

A crosslinking agent composition for water-compatible resins which comprises a hydrophobic crosslinking agent, a water-soluble organic compound, one or more oily media selected from among hydrocarbon-based solvents and ketone-based solvents having a solubility parameter of 9.0 (cal/cm.sup.−3).sup.1/2 or less, and an aqueous medium. The crosslinking agent composition can improve the storage stability of a water-compatible resin composition. The water-compatible resin composition which contains this crosslinking agent composition can give cured objects satisfactory in terms of water resistance and solvent resistance and is suitable also for use in wet-on-wet coating.

A method of manufacturing a processed body having a hydrophobic and water-repellent surface, and a processed body having a hydrophobic and water-repellent surface. The method includes: a step of contacting a member made of a crystalline or semicrystalline polymer with a solvent in a solvent-contacting region; and a step of taking the member contacted with the solvent out of the solvent-contacting region and drying the member.
