Disclosed herein are methods specifically tailored for facilitating the mitigation of cosmetic impressions associated with fingerprint impressions on surface(s) of articles of manufacture made from anodized substrates. To this end, such methods provide for removal of fingerprints by enzymatically functionalizing the surface(s) of the article of manufacture (e.g., a cosmetic coating thereof) to generate an enzymatically active surface and activating such enzymatically functionalized surface(s) to promote such fingerprint removal. Thus methods and articles of manufacture made in accordance with such methods provide improved end-use utility and functionality of many products for consumer electronic applications, automotive applications, building materials applications, and the like.

The present disclosure is generally directed to a mold inhibiting composition. The mold inhibiting composition can be used to treat various different substrates, including building material products, such as facing layers for wallboard. In general, any suitable paper product may be treated with the composition. The composition contains a mold inhibiting agent in combination with a defoamer. The mold inhibiting agent may comprise a pyrithione. The defoamer, on the other hand, may comprise an oil based defoamer containing metal oxide particles, such as silica particles. The mold inhibiting composition can be combined with a water repellent and applied to a substrate without excessive amounts of foam or froth being formed. The defoamer is selected so as to not interfere with the resulting water absorption properties of the product.

The embodiments herein relate to a non-aqueous liquid foul release coating composition and process for controlling aqueous biofouling on man-made objects, including a curable resin system (A) comprising i) a curable polymer free of fluorine atoms and having a backbone selected from a polyurethane, a polyether, a polyester, a polycarbonate or a hybrid of two or more thereof, and having at least one terminal or pendant alkoxysilyl group and ii) optionally a curing agent and/or a catalyst; and (B) a marine biocide and/or a non-curable, non-volatile compound is selected from the group consisting of fluorinated polymers, sterols and sterol derivatives, and hydrophilic-modified polysiloxane oils, wherein the coating composition is essentially free of a curable polysiloxane, and wherein the coating composition is essentially free of non-curable polysiloxanes other than non-curable hydrophilic-modified polysiloxane oils.
