Antimicrobial formulations and coatings for medical devices and processes therefor are disclosed. The formulations include at least one water permeable polymer with at least one antimicrobial agent in a liquid medium and are prepared by wet milling the components and can form antimicrobial coatings having uniformly dispersed particles having an average size of no greater than 50 microns.

Antimicrobial coatings for medical devices and processes for preparing such coatings

The present invention provides a nanocapsule of a blocked isocyanate encapsulated within a polymeric nanosphere. In one aspect, the polymeric nanosphere is functionalized. Free isocyanate functionality is released upon thermal annealing or UV exposure of the nanospheres containing the blocked isocyanate. This present invention also provides a novel method for encapsulating isocyanates in aqueous media. In one aspect, the method comprises miniemulsion polymerization. The thermally or UV deblocked isocyanate can be used as an active functional group for many potential applications.

Nanoencapsulation of isocyanates via aqueous media

The present invention is directed to a fatty amide (meth)acrylate monomer, methods of making the monomer, and latex polymers comprising the fatty amide (meth)acrylate monomer. The monomers are derived by reacting unsaturated vegetable oils with ethanolamine or substituted ethanolamine. The vegetable oil derivative is then reacted with either (meth)acryloyl chloride or (meth)acrylic acid to form a fatty amide (meth)acrylate monomer or the product of the reaction of hydroxyethyl (meth)acrylate reacted with isophorone diisocyanate to form a urethane fatty amide (meth)acrylate monomer. The increased hydrophilicity of the fatty amide (meth)acrylate monomer facilitates the diffusion through the aqueous phase. The monomer synthesis is designed to be glycerol ester-free to increase long term stability for monomers and polymers.

Glycerol ester-free functionalized vegetable oil derivatives and their latex compounds

An ethylenically unsaturated vegetable oil is modified by the addition of an enophile or dienophile having an acid, ester or anhydride functionality. The modified vegetable oil is then reacted with a polyethylene glycol (PEG) derivative along with a functional vinyl monomer or a polyethylene glycol derivative that contains a vinyl functionality to form a vegetable oil derivative. The vegetable oil derivative is useful in forming latexes and coatings.

Latex compositions comprising functionalized vegetable oil derivatives

The present invention relates to polyurethane powder coating compositions that do not split off blocking agents and have a low stoving temperature. The powder coating compositions contain a hydroxyl functional binder component having a content of carboxyl groups of from 0.5 to 2.0 wt. %, a polyaddition compound, at least one zinc compound as a hardening catalyst, and a compound reactive to carboxyl groups.
