Abstract of the Disclosure: An agent for the after-care or
treatment of the heartwood of wooden masts and the like,
based on a chemical compound which releases methyl iso-
thiocyanate, contains tetrahydro-3,5-dimethyl-2H-1,3,5-
thiadiazine-2-thione (dazomet) and an essentially anhydrous
solvent or dispersant, with the proviso that the mixing
ratio and intrinsic viscosity of the solvent or dispersant
and, where relevant, the concomitant use of a thickener
result in the said agent having a pasty consistency.
