Wood preservation facilities, copper azole : chapter H-2

2. Physical and Chemical Properties

Copper as Cu and azole as tebuconazole, the two active components of CA-B, are used because of their fungicidal and termiticidal properties and their ability to offer long-term protection in the wood. Copper monoethanolamine complexes allow the copper to be transported and deposited in the wood cells.

General physical and chemical properties can be obtained from manufacturers’ material safety data sheets (MSDS) and from labels for pesticide product. Electronic copies of the pesticide label can be obtained from the Health Canada website (3).

The physical and chemical properties of CA-B and its constituents are outlined in Tables 2 (3, 5).
