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.

The invention provides a novel hydrophilic polymer and latex polymer blend coating formulation and compositions thereof, and their use on various devices (e.g., prophylactic and medical devices) to form hydrophilic and flexible coatings with durable lubricity.

A puncture sealing agent is disclosed which comprises natural rubber latex, an aqueous solution of an adhesive and an antifreezing agent. The adhesive is a carbohydrate and the puncture sealing agent comprises a solid content resulting from the natural rubber latex in an amount of 21 wt % or less, based on the total weight of the puncture sealing agent.

Disclosed herein is a polymeric paint additive that increases the open time and the flow and leveling of paint compositions, as well as, maintaining/improving paint film properties such as scrub resistance, water sensitivity, surfactant leaching and stain removal. The polymeric open time additive preferably has a high glass transition temperature, e.g., above 100 C., as determined by the well-known Fox's equation, and molecular weight of less than 20,000 Daltons (number average molecular weight). The particle size of the inventive polymeric open time additive is in the range of about 130 nm to about 230 nm (volume average), prior to being dissolved in a basic solution, such as an aqueous architectural composition.
