Procedure

3000 g of treatment solution was prepared by diluting 90 g (50% solids) of polymer with 2000 g of tap water containing 3 drops of Tego Foamex 805 defoamer with stirring for 20 minutes. (Tap water optionally containing additional surfactant, such as a metal salt of dodecylbenzene sulfonic acid or an alkyl ethoxylate) (0.06%) To the well stirred solution was slowly added 22.5 g (20% DCOIT dissolved in propylene glycol phenyl ether with 0.04% PG, for a final concentration of 1500 ppm DCOIT). Tap water was added to make 3000 g of total solution and the solution was stirred for 60 minutes, and used as is to treat wood.
