ANVENDNING AV KOPPAR- OCH/ELLER ZINKSALTER AV ETTIKSYRA OCH/ELLER PROPIONSYRA SOM KONSERVERINGSMEDEL FOR TRE

摘要

The present invention deals with preservatives for wood and other organic fiber products. It is based on water-soluble copper and zinc salts of weak acids. After a solution of the salts has been introduced into the wood the salts are converted so that relatively insoluble preserving metal radicals are precipitated in the wood. The protecting effect of the preservatives and the precipitation of the metal radicals can be increased by suitable additives.
