Investigation of bis-[1-(dimethylamino)-2-propanlato] copper (II) as a wood preservative

Bis-[l-(dimethylamino)-2-propanolato] copper (II) (CuDMAP) in the vapor phase was used to treat oriented strandboard (OSB) to investigate its potential as a wood preservative. Treatment time and temperature greatly influenced copper penetration and retention. The leachability of the CuDMAP in OSB was similar to that of ammoniacal copper sulfate (ACS). The efficacy of CuDMAP as a preservative was assessed with soil block tests and compared with that of ACS and chromated copper arsenate (CCA). Results were inconclusive as to the efficacy of CuDMAP against fungal decay.
