Koppers Celbrite protects unseasoned wood from the growth of mould and sapstain fungi during drying, transport and storage.
Celbrite is a concentrate which is diluted with water to make a solution for industrial application to freshly felled or freshly sawn wood by dip or spray.
Mould and sapstain fungal spores occur in the air and settle on surfaces, including the surfaces of freshly felled and freshly sawn wood. If conditions are suitable, the spores are able to germinate.
Celbrite treated wood has been treated by the correct application of Koppers Celbrite by immersion or spray, and then allowed to dry. Celbrite treated wood is protected against the growth of mould and sapstain fungal hyphae.
Koppers Celbrite treated wood is not protected against wood destroying insects or wood decaying fungi. Preservative treatment is required to protect against these organisms.
The timber to be treated should be freshly felled and freshly sawn to avoid mould and sapstain development before treatment. Timber surfaces should be free of bark, soil, ice or sawdust. Timber packs should be stickered to ensure all wood surfaces are completely covered by the treating solution.
The Koppers Celbrite treating Solution is applied by immersion or spray. Each piece of timber should be dipped for at least 30 seconds, to ensure complete coverage and sufficient uptake. Packs should be dipped for at least 1 minute.
Dip tanks should be agitated at the beginning of each working day, and accumulation of sawdust in the tank should be avoided.
The effectiveness of the preventive treatment depends upon the use of an appropriate concentration for the timber species, region, season and weather conditions.
Celbrite Treated wood should be held until surfaces are dry within a bunded area on a site which is maintained to prevent loss of treatment product to the environment.
Treated timber will dry naturally, but to minimise the drying period, packs should be stickered and then allowed to stand in a well-ventilated area. Care should be taken not to despatch timber which still contains free liquid on its surfaces.
