BARamine® Technology

BARamine® is a platform of technologies that offer: • EPA-registered preservative additive • Increased Efficacy

• Improved decay protection • Penetration enhancement

• Enhanced mold protection • Solution stability

What is BARamine®?

This proprietary patented technology provides the most effective copper azole system available only from Lonza

• Combination of actives enhances protection against copper tolerant fungi • Improved protection

against aggressive fungi, e.g. Antrodia, Serpula

• Better control of standard fungi, e.g. Coniophora, Poria

• Improved preservative penetration offers better protection

BARamine® Decay Efficacy

• Increased solution uptake leads to deeper penetration • Improved management of

extractives in recycled solution

• Extractives can reduce pickup and penetration in wood

Penetration Enhancement

Pine Matched Boards

BARamine® significantly improves penetration of recycled CA-C preservative into wood similar to that of fresh solution.

In a commercial trial on 2”x6” lumber, significantly more preservative reached the middle and inner zones when used in combination with BARamine® as compared to Copper Azole alone.

Solution Stability with BARamine® Technology

Charge without BARamine® displays undesirable copper residue

BARamine® treated wood better penetrates with less residue remaining on the wood

Increased solution stability leads to improved penetration and better appearance

BARamine® provides superior mold protection • Allows reduced reliance

on isothiazolones Note: Additional moldicide requirements dependent upon

• Treating cycle – FC / MFC • Geographical location • Customer expectations –

time in storage • Storage practices – wrapped,

shed, open etc.

Enhanced Mold Protection

• Treated wood with BARamine® and Lumbrella® has desirable dry appearance and low drippage even at higher water repellent loadings

Water Repellency

• Boosts existing Copper Azole preservation • Improved penetration equals better protection thus

reducing potential for failures • More consistent preservative distribution for better

performing treated wood • Improved resistance to certain aggressive copper-tolerant

fungi reduces likelihood of rot • Broad moldicide protection for brighter, cleaner looking

wood • A patented technology that is only available through

Lonza
