An improved method for fixedly binding particles of a solid, heat absorbing material or additive, especially polymer additives, to the surface of prepolymer and/or polymer particles.

Polymer particle coating method

Efficient antimicrobial additives are provided comprising a wettable, cake-forming inorganic material having dispersed therein an inorganic or organometallic antimicrobial agent capable of releasing antimicrobial metal ions. These antimicrobial additives are especially effective for use in cements, mortars and cementitious compositions.

Antimicrobial cements and cementitious compositions

An improved method for fixedly coating powder coating prepolymer and/or polymer particles with microparticles of solid, heat absorbing polymer additive materials, especially antimicrobial additive materials.

Antimicrobial powder coatings and method

Novel dispenser means are provided for mixing and dispensing two-part curable compositions wherein the mixer elements are isolated from the curable components.

Dispenser with dynamic mixer for two-part compositions

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. Another embodiment of the invention is an article prepared from the polymer compositions comprising the microcapsules and a matrix polymer.

Encapsulated inorganic antimicrobial additive for controlled release

According to the present invention there are provided antimicrobial catheters and other medical devices having controlled release of an antimicrobial metal or metal ion. Specifically, antimicrobial catheters and other medical devices manifest antimicrobial properties as a result of the incorporation therein of antimicrobial microcapsules comprising an inorganic antimicrobial agent and a hydrophilic polymer.
