You can have confidence in Tanalith®

copper based preservatives

The original Tanalith® E formulations using

the unique copper and azole preservative

system were developed and patented for

the European market in the early 1990’s in

response to increasing regulatory pressure

on chromium and arsenic containing pre-

servatives. Since those times copper based

preservatives have become the dominant

and most widely used treatments globally

particularly for residential and other non-

industrial use wood products. They com-

bine robust protection for wood against

decay and insects with high levels of safety

and convenience for users.

Remember these important tips for use of Tanalith® treated wood

products;

All end cuts, rebates, drill holes and notches should be resealed

with an approved “in-can” supplementary timber protective such

as Tanalised® Enseal. It is recommended not to place cut ends into

ground contact.

All sawn timber products in outdoor situations are recommended

to be painted, stained or sealed for best performance against dis-

colouration, mould and dimensional distortion. Even a simple

fence paint can make a dramatic difference to the appearance of a

timber structure after a few years weathering.

Use hot dipped galvanized steel or other corrosion resistant fas-

teners for all exterior timber applications. For heavy load fasten-

ers (≥ 6 mm thick), when in contact with high retention treated

wood (H4 & H5), for permanent structures (50 year expected

service life) or in proximity to sea water, stainless steel (type

316) is recommended.

You will never regret the small additional costs of taking these

steps when you appreciate the long term benefits of durable out-

door timber structures protected with Tanalith® copper based

preservative.

Dispose of treated wood wastes properly. Do not burn treated

wood for heating, cooking or as a means of disposal.

Tanalith® Copper Based Preservatives

Product Formulation

Tanalith® E Copper and azole fungicides

(propiconazole and tebuconazole) in a

solution form

Tanalith® Eµ Copper and azole fungicides

(propiconazole and tebuconazole) in a

dispersed or suspension form

Tanalith® Q Copper and quaternary ammonium fungi-

cide DDAC (didecyl dimethyl ammonium

carbonate) in a solution form.

See individual product data sheets for full details.

Lonza Wood Protection offer a range of copper based pre-

servatives for protection of wood and timber products

used in general outdoor and ground contact use. These

advanced preservatives incorporate copper in combina-

tion with azole or quaternary ammonium co-biocide wood

protection system.

Solution Copper:

Tanalith® E and Tanalith® Q incorporate a solution form of

copper and co-biocides where the copper is present as an

ethanolamine complex hence the dark blue colour. This

form of copper is suitable for treatment of the widest

range of different species including hardwoods and re-

fractory or difficult to treat softwoods such as Red Baltic

pine (Pinus sylvestris) and similar.

Dispersed Copper:

Tanalith® Eµ uses copper in a dispersed or micronised

form where the copper is present as a very fine suspen-

sion in water. This form of copper has some important

advantages and is suitable for treatment of permeable

species such as Radiata pine and Southern Yellow pine

(Pinus elliottii and similar).

Treatment Plant and Processing:

Tanalith® copper based preservatives are intended for use

through approved industrial pressure treatment facilities

only. Conventional water borne treatment plants and treat-

ment processes are suitable. Some plant and process modifi-

cations may be required if changing from CCA (copper chromi-

um arsenate) preservative. All wood and timber products

must be dry (< 20% M.C.) and clean for treatment. Contact

Lonza for further details.

Optional Additives:

Lonza has a range of optional additives such as colouring

additives, water repellents to extend the performance of

Tanalith® copper based wood preservatives.

Tanatone® In-treatment colour additive that provides

a durable penetrating coloration for the

treated wood.

WR Additive Water repellent additive to improve water

repellency and dimensional stability of

the treated wood.

Tanaguard® Anti-mould additive to minimise mould

development on the surface of the treated

timber.

BARamine® Penetration enhancement for treatment

of heartwood and refractory timber

species.

Not all additives may be available, compatible or suitable for

certain treatment applications. Consult Lonza for further

details.

International Acceptance:

Tanalith® copper based preservatives conform to the latest

Unites States EPA, European Union and Australian regulatory

directives regarding preservatives for use in wood products

for residential and close human contact use such as decking,

outdoor furniture, playground equipment and similar.

Tanalith® and other brand copper based preservatives from

Lonza are in wide use around the world including in many

countries in Europe, the United States, Asia and more specifi-

cally, New Zealand, Australia and Fiji in the Pacific region.

Consult Lonza for details of approvals and requirements for

specific countries.
