CARBOQUAT 250 T
Dialkyl Dimethylammonium Bicarbonate/Carbonate Wood Preservative
Carboquat 250 T, a true fifth-generation quaternary from Lonza, is the most innovative quatbased
wood preservative since the introduction of DDAC (didecyldimethyl ammonium chloride)
in the 1970’s. While retaining all of DDACs broad-spectrum potency, Carboquat 250 T has a
lower ionic strength afforded by replacing the chloride counter-ion with bicarbonate/carbonate.
