The original developer of copper azole technology more than 20 years ago, Lonza is now supplying its fifth generation formulation. Our Wolman® E preservative with BARamine® technology is the most advanced copper azole system on the market. Only available from Lonza, this formulation incorporates patented technology that provides enhanced protection against decay organisms, including copper-tolerant fungi, and a deeper and more consistent penetration of preservative in the wood. This enhanced technology is available in both dissolved and micronized formulations. 

Wolmanized® Outdoor® Wood is ideal for decks, retaining walls, fences, picnic tables, planter boxes, raised garden beds, walkways, sill plate and structural members. Wolmanized® Outdoor® Wood, at appropriate retention levels, can be used for Above Ground, Ground Contact, and Heavy Duty Ground Contact applications.
