This invention relates to preservatives at neutral or slightly acidic pH containing copper complexes and calcium, magnesium, and/or zinc cations for protection of wood, cellulose, hemicellulose, and lignocellulose from decay caused by fungi.

Copper complexes and their use as wood preservatives

This invention relates to wood preservatives containing copper complexes and calcium ions, zinc ions or calcium and zinc ions for protection of wood, cellulose, hemicellulose, lignocellulose, cellulosic materials and articles derived from cellulosic materials from decay caused by fungi. The calcium ions, zinc ions, or calcium and zinc ions improve the penetration of copper preservative agent into the interior of a treated material or article.

Wood preservatives containing copper complexes

Semiconductor processing compositions comprising amidoxime compounds having two or more amidoxime functional groups and their use in semiconductor processing to remove photoresist, polymeric materials, etching residues and copper oxides from semiconductor substrates, particularly substrates comprising copper, low-k dielectric material, titanium nitride, and/or titanium oxynitride.

Nitrile and amidoxime compounds and methods of preparation for semiconductor processing

The present invention is directed to an aqueous dispersion composition which comprises an ethylene-unsaturated carboxylic acid ionomer resin (A) neutralized with a mixture of ions including at least one divalent metal ion and at least one ammonium ion, (B) a non-water soluble vapor phase corrosion inhibitor, and (C) water. The dispersion exhibits good shelf-life and excellent rust-prevention properties. Durable corrosion resistant ionomeric coatings can be easily formed therefrom, which when applied to metal surfaces and baked, can form a rust-preventive coating layer showing excellent coating adhesion both to the metal surface and to an over coat paint. Such coatings are particularly useful when applied to a vehicle body or part thereof.

Aqueous dispersions containing ionomer resins and rust-preventive ionomeric coatings made therefrom

Processes for providing durable antimicrobial surfaces are disclosed that comprise treating a polymer substrate surface with formaldehyde followed by treatment with an antimicrobial peptide. Further embodiments include articles, including medical devices, characterized by a durable antimicrobial surface provided by the processes of the invention.

Process for providing antimicrobial surfaces

Complexes of copper and/or zinc with hydrolyzed olefin/maleic anhydride copolymers were solubilized in ammoniacal solution providing preservative solutions that fully penetrate wood. With loss of the ammonia from the wood, the complexes were stably retained in the wood providing a long lasting preservative.

Metal salts of hydrolyzed olefin/maleic anhydride copolymers and their use as wood preservatives

Complexes of copper and/or zinc with molybdate and/or tungstate were solubilized in ammonia or ammoniacal solution providing preservative solutions that fully penetrate wood. With loss of the ammonia from the wood, the complexes were stably retained in the wood providing a long lasting preservative.

Tungstate and molybate wood preservatives

Complexes of ibuprofen and copper and/or zinc were solubilized in ammoniacal solution providing preservative solutions that fully penetrate wood. With loss of the ammonia from the wood, the complexes were stably retained in the wood providing a long lasting preservative.

Ibuprofen complexes as wood preservatives

Complexes of tropolone and copper and/or zinc were solubilized in ammoniacal solution providing preservative solutions that fully penetrate wood. With loss of the ammonia from the wood, the complexes were stably retained in the wood providing a long lasting preservative.

Tropolone complexes as wood preservatives

This invention relates to copper complexes that significantly reduce the decay of wood, cellulose, hemicellulose, and lignin caused by fungi. A process for treating such materials with these copper-containing anti-fungal agents is also disclosed.

An improved aqueous cathodic electrocoating composition having a binder of an epoxy-amine adduct and a crosslinking agent; wherein the improvement is the use of a crosslinking agent having at least one, preferably a plurality of morpholine dione groups per molecule. Electrodeposited finishes are formed that have reduced volatile emissions and film weight loss when heated to cure.

Cathodic electrocoating composition containing a morpholine dione crosslinking agent

An improved aqueous cathodic electrocoating composition having a binder of an epoxy-amine adduct and a polyisocyanate crosslinking agent; wherein the improvement is the use of a polyisocyanate crosslinking agent having at least one crosslinkable morpholine dione group per molecule. Electrodeposited finishes are formed that have reduced volatile emissions and film weight loss when heated to cure.

Cathodic electrocoating composition containing morpholine dione blocked polyisocyanate crosslinking agent

The rate of aminolysis of butyrolactones is predictably adjusted by attaching a substituent having a known field effect value (F) to the alpha position before reacting the substituted buytrolactone with an amine. The aminolysis product is a gamma-hydroxy amide. The resulting materials are useful as the cross-linking agents in a variety of coatings and coatings processes.

Preparation and use of gamma-butyrolactones as cross-linking agents

The present invention concerns the preparation of polymers of low polydispersity and/or controlled molecular weight and architecture employing living free radical polymerization initiated by an alkoxyamine initiator or nitroxide plus, optionally, a free radical initiator, the polymer produced thereby; selected nitroxide and alkoxyamine initiators; and a process for making the initiators; the polymeric products being useful in protective coatings.
