Provided is a solvent borne coating composition comprising (a) one or more polymeric biocide comprising multivalent metal cations and multivalent organic anions, (b) one or more polymer-encapsulated biocide, and (c) one or more ethoxylated triglyceride that has average number of moles of ethylene oxide units per mole of triglyceride molecules of 10 to 45. Also provided are a method of making such composition and a method of using such a composition.

Stable biocide compositions

A composition is provided, comprising microcapsules, wherein said microcapsules comprise a core and an outer shell, wherein said core comprises one or more water-insoluble compound having melting point above 15&#xb0; C., wherein said outer shell comprises one or more amino resin that is a reaction product of reactants comprising one or more polyamine and formaldehyde, and wherein said composition further comprises one or more formaldehyde scavenger, one or more reaction product of said amino resin with a formaldehyde scavenger, or a mixture thereof. Also provided is a method of making such a composition.

Microcapsules

Described are methods of determining free hydrophobic active in aqueous formulations including the steps of encapsulating a hydrophobic active, preparing a formulation containing encapsulated hydrophobic active, adding a cyclodextrin to the formulation, thereby entraining any free hydrophobic active; and quantifying the amount of free hydrophobic active.

Method for measuring encapsulation efficiency for hydrophobic actives

A coated substrate having an epoxy coating. The epoxy coating contains 4,5-dichloro-2-n-octylisothiazolin-3-one.

Antifouling paint system

A composition containing 4,5-dichloro-2-n-octylisothiazolin-3-one and an activated carbon having a surface area of at least 700 m/g.
