What does CBA stand for?

According to Monaghan, many conventional acrylic waterborne semitransparent stains have poor adhesion to the new types of wood treatments, such as copper azole, leading to early failures on exposure.

Horizontal up exposures with and without foot traffic on cedar, Trex, weathered CCA, copper azole treated pine, Ipe, and mahogany were evaluated.

The most widely used replacements for CCA treatment are ACQ (alkaline copper quaternary compound), copper boron azole (CBA) and copper azole (CA-B) treatments.

Copper Azole (CBA) Wolmanized[R] Wood products treated with Natural Select[TM] Copper Azole have been used effectively around the Wolmanized[R] world since 1992.

residential uses, replaced by several chemical compound treatments, namely alkaline copper quat (ACQ) and copper azole.

Demand for monoethanolamine -- which rapidly gained popularity in the wood treatment market as chromated copper arsenate was phased out in favor of alkaline copper quaternary and copper azole -- will expand at a healthy rate through 2012 despite decelerating significantly from the 1997-2007 pace.

The biggest factor affecting the wood coating market today is the change from CCA pressure-treated wood formula to new alternative formulas such as alkaline copper quat and copper azole," said Rick Mendenhall, manager, Wolman Certified Contractor Program.
