TIB KAT 808 is a copper derivative of naphthenic acid.
Although commonly called salts of naphthenic acid, TIB KAT 808 is not ionic, but is a covalent coordination complex, hence its lipophilic character.
TIB KAT 808 is most widely used in wood preservation and for protecting other cellulosic materials such as textiles and cordage from damage by decay, fungi and insects.
Other metal naphthenates are used as paint driers, rubber adhesion promoters, lubricant additives, and catalysts where oil solubility is required.
Composition
TIB KAT 808 has the general formula Cu(RCOO)2.
TIB KAT 808's structure is assumed to resemble that of copper(II) acetate.
TIB KAT 808 is commonly prepared by treatment of naphthenic acid with copper(II) compounds such as basic copper carbonate or copper hydroxide.
Even copper(II) sulfate can be treated with sodium or potassium naphthenate in aqueous solutions.
The reaction of copper metal with naphthenic acid, which has been used commercially, requires more forcing reaction conditions and generates excessive impurities.
Less commonly practiced methods of synthesis include reaction of copper acetate with naphthenic acid, which generates acetic acid as a byproduct, and electrochemically using copper electrodes.
TIB KAT 808 is a dark-green, amorphous glassy solid, paste or viscous liquid that is freely soluble in various organic solvents including mineral spirits, diesel fuel and other fuel oils, and creosote-petroleum mixtures.
TIB KAT 808 free of any solvent has a copper content ranging from 10-13% by weight, depending on the acid number/molecular weight of the naphthenic acid used.
The properties of TIB KAT 808 treating solutions are dependent on the type of oil used as the carrier.
TIB KAT 808 sold for pressure treatment of wood is typically supplied as an 8% copper (as metal) concentrate for dilution to 0.5-1.5% copper (as metal) treating solutions.
TIB KAT 808 sold at retail for consumer use is typically a 1% or 2% copper ready-to-use solution in mineral spirits or other similar solvents.
Waterborne TIB KAT 808 formulations are also available as a 5% copper (as metal) concentrate and used after further dilution with water.
TIB KAT 808 is a copper carboxylate made with naphthenic acid.
Naphthenic acids are by-products of petroleum.
TIB KAT 808 is not registered as a pesticide.
TIB KAT 808 exhibits a wide range of efficacy toward most decay fungi, termites, and many other wood destroying insects.
TIB KAT 808 is a general-use wood preservative.
TIB KAT 808 is also used as a textile preservative.
TIB KAT 808 has been used safely in greenhouse applications.
TIB KAT 808 is recommended for the treatment of beehives, by which it has not harmed bees or significantly affected the quality of honey produced.
TIB KAT 808 is approved as an over the counter topical treatment for treating horses and ponies for thrush at concentrations of 37.5%.
Livestock exposed to TIB KAT 808 shelters and water troughs exhibited no adverse health effects.

Wood preservative and other uses
TIB KAT 808 is an active ingredient used predominantly in industrial and commercial wood preservation for non-pressure (dip/brush/spray) and pressure treatments (vacuum/full cell) to protect against fungal rot, decay, termites and wood-boring insects in unfinished wood and various fabricated wood products.
This preservative is also used for remedial treatments to in-service poles including internal/external surfaces at ground or below ground level via brush/trowel, mechanical injection, or bandage wrap.
Wood treated with TIB KAT 808 is specified for exterior above ground, ground contact, below ground and fresh water contact use applications.
TIB KAT 808 is also used as protective wood preservative surface treatments when applied to bare seasoned wood.
For this use, TIB KAT 808 is readily available to the general public and sold over-the-counter to consumers as wood protection coatings and water repellants.
TIB KAT 808 has been commercially produced and industry utilized as wood preservative since its first use in Europe in 1889.
TIB KAT 808 is typically formulated in hydrocarbon solvents such as diesel, heavier fuel oils, or mineral spirits, although waterborne formulations are also used to preserve dimensional lumber and in non-pressure applications such as wooden roof shakes and shingles.
TIB KAT 808 in oil is a heavy duty wood preservative used for utility poles, railroad crossties and bridge timbers, highway construction such as posts and guardrails, fence posts, and piles.
Preparation
TIB KAT 808 is prepared by the reaction of copper(II) hydroxide or basic copper(II) carbonate with naphthenic acid in a hydrocarbon solvent or by the reaction of copper(II) sulfate with sodium naphthenate.
TIB KAT 808 is insoluble in water.
TIB KAT 808 is used to control fungi and mildew in textiles, woods, and in antifouling pigments.
TIB KAT 808 is usually marketed as a solution containing 8% copper.
