Permacure ACQ is a new-generation wood preservative and is considered an environmentally friendly choice.
A water-borne preservative, it protects wood from wood-destroying fungi, insect larvae and termites. Permacure ACQ can be used for structural timber, agriculture poles (pine and eucalyptus) and transmission poles.
It is applied by impregnation into the timber by vacuum pressure at a timber treatment plant. Permacure ACQ can be used for hazard classes H1 to H5.
Ammonium Copper Quaternary, or ACQ, is new generation compound recently introduced in countries where there is a demand for alternatives to CCA. A waterborne preservative, it is applied by vacuum pressure impregnation at a timber treatment plant.Dolphin Bay supplies two brands of Permacure ACQ: Permacure ACQ 223 and Permacure ACQ 224.Permacure ACQ 223 has two active ingredients, copper and alkyldimethyl benzammonium chloride (ADBAC). Permacure ACQ 224 has the active ingredients copper and didecyldimethylammonium chloride (DDAC).The copper in each brand functions as a bactericide and fungicide, just as in Permacure CCA, allowing the treated wood to be resistant to biological attack. The pressure impregnation of the bivalent copper into timber allows the preservative to bond to the cellulose and hemicellulose within the wood.
The quaternary ammonium salts ADBAC and DDAC act as biocides, increasing the tolerance of treated timber to copper-resistant bacteria and fungi, and also acting as an insecticide.A quaternary ammonium salt is a compound in which the number of bonds to a central nitrogen atom is four instead of three, leading to a positively charged ion (balanced by the chloride anion).These quaternary ammonium salts also bond to cellulose in the wood, and provide an action to allow for the bonding of bivalent copper ions to the cellulose structure.The action of copper and quaternary salts results in Permacure ACQ being an effective and environmentally friendly wood preservative.
Permacure ACQ is a new wood preservative offering a high level of protection against the elements and weathering. It is applied by industrial vacuum-pressure impregnation at a timber treatment plant.Permacure ACQ can be used for wood in hazard classes H2 to H5, where H2 stands for low exposure to the elements and weathering, and H5 for high exposure, according to the South African National Standards. While there is only one method of application of this preservative, its concentration increases with corresponding expected levels of exposure of the timber.The timber can be installed after it has been treated and the fixation period has passed. The fixation period allows Permacure ACQ to bond with the cellulose of the wood.Permacure ACQ-treated timber can be used for:
- Structural timber: Used in the construction of homes, e.g. roof trusses, indoor and outdoor decking.
- Agricultural poles: Used in vineyards and orchards. Permacure ACQ poles are safe and easy to handle as the preservative is fixed within the timber and does not leach out.
- Transmission poles: Electrification or telecommunications transmission lines.
- Building and fencing.
Permacure ACQ prolongs the natural life of timber by up to 25 years, depending on the final application. Permacure ACQ is also classified as a green alternative to existing timber preservatives. Timber treated with this wood preservative is safe to handle.
Permacure ACQ adds a distinctive green tint to the timber. A pigment can be introduced at the timber treatment plant, colouring the timber in a range of green to brown hues.
Permacure ACQ-treated timber can be painted, although this is not necessary.
