Wood treatment - risk classes

Dye-impregnated used is TANALITH E3492.
Presentation:
Wood is too valuable material to allow degradation or destruction by Xylophagy insects and fungi infestation.
The treatment TANALITH E protects the wood, providing a much longer period of use thereof, away from the attack of insects, termites, white, red and brown rots, soft rot of marine organisms. TANALITH E is a product of Arch Timber Protection Company made without chromium and arsenic.
Use:
It is appropriate to treat all species of wood and has a high efficacy for both wood above the ground and in contact with the ground. It proved a high efficiency by major attacks against destructive agents such as molds, fungi and insects in field tests conducted in Europe, North America and Australia. TANALITH E can be used in countries where  products containing heavy metals are banned and where issues of environmental protection is of major importance.  
Wood treated with TANALITH E shows a green uniform colour, with excellent properties to weather conditions and doesn't smell. There are also a range of paints with pigments if calling different colors. Because of the excellent exhibition and original formulation, TANALITH E became a very popular choice in the treatment of garden furniture, playground equipment and other garments made of wood.

Treatment is applied through a standard vacuum-pressure process. TANALITH E's chemical components are very well fixed in the wood structure, giving the possibility of using both products for different types of furniture and in agriculture (eg: vine pegs).
