Abstract: Encapsulated cure systems are provided wherein a curative is incorporated into a solid or semi-solid carrier material whereby mere fracturing or failure of the capsule wall encapsulating such cure systems will not provide for or allow sufficient release of the curative. Also provided are adhesive systems incorporating said encapsulated cure systems.

Abstract: The present invention provides for a color stable antimicrobial coatings and coating systems comprising a silver ion-exchange type antimicrobial agent. In particular, coatings and coating systems having little, if any, discoloration are provided with no loss of antimicrobial efficacy.
Abstract: This invention provides for a curable antimicrobial coating system comprising a base coating composition and a top coat coating composition wherein each contains and antimicrobial agent. The base coat forms a non-hydrophilic polymer layer and the top coat preferably forms a hydrophilic polymer layer or a non-hydrophilic polymer layer which does not preclude the release of the antimicrobial agent. This two-layer coating is especially designed for erosive environments and provides continual antimicrobial activity regardless of the stage of wear or erosion.
Abstract: The invention relates to a microcapsule comprising an inorganic antimicrobial agent coated with a hydrophilic polymer. The hydrophilic polymer is able to absorb sufficient water as to enable the action of the encapsulated antimicrobial agent. These microcapsules are useful to impart antimicrobial activity and can be used in polymer compositions, sprays and coatings. A method of preparing the microcapsule by treatment of the antimicrobial agent with a solution of the hydrophilic polymer is provided. Another embodiment of the invention is a method of preparing the microcapsule by coating of the antimicrobial agent with a polymer precursor followed by treatment with a reactive ingredient. Another embodiment of the invention is a method of preparing the microcapsule by melt compounding the antimicrobial agent with the hydrophilic polymer followed by grinding to the desired particle size. Polymer compositions comprising the microcapsules and a matrix polymer are also provided.
