Chemonite® ACZA

For more than 75 years, Chemonite® as either ACA (Ammoniacal Copper Arsenate) or ACZA (Ammoniacal Copper Zinc Arsenate) treatment has protected wood used in industrial applications from termites and fungal decay. Chemonite® ACZA treated wood is ideal for industrial applications including marine piling, utility poles, and railroad ties.

Especially effective in treating refractory species, this waterborne preservative extends the service life of wood with consistently penetration. Along with decades of commercial production and performance, long-term field tests and laboratory fungal and termite tests have demonstrated the efficacy and service life of wood treated with ACZA.

Chemonite® ACZA treated wood offers all of the benefits of wood along with prolonged service life. It is leach-resistant and is protected against the major causes of wood degradation: decay and termites (including Formosan), marine organisms, carpenter ants, and woodpeckers. It can be stored, handled, and worked with just as untreated wood. Chemonite® ACZA also displays the properties of a Class B fire retardant.
