This change created a need to investigate the performance of coatings on these new Cu-based preservatives as compared with CCA. This study evaluated performance of a number of semitransparent deck stains on CCA, alkaline copper quat (ACQ), copper azole (CA), and untreated wood samples during 3 years of natural weathering. Coatings were evaluated for their ability to reduce water uptake, color change, checking of wood, and mildew growth and to improve general appearance of preservative-treated wood samples. Overall, Cu-amine-treated wood had on average 50% higher water uptake than CCA-treated wood samples. Although solvent-based coatings had better water repellency performance on CCA-treated and untreated wood, there was no significant difference in water-repellent effectiveness (WRE) between water-based and solvent-based coatings on ACQ- or CA-treated wood. All preservative-treated woods had less color change and better visual ratings than those of untreated wood samples. Based on image analysis which was used to determine the total area of surface checking on samples after 3 years, preservative treatments had no significant effect on reducing checking of wood while coatings reduced surface checking by 30-40%.

These chemicals are essential in leather manufacture to ensure that the leather is not degraded by mold growth and to safeguard the leather’s quality, usefulness and commercial value. Over the years the use of some fungicides has been disallowed due to their toxicity or other issues, while others may be restricted in the future. Consequently, tanners are faced with a more limited number of products to choose from when it comes to these chemicals. In an effort to address this need, Zenith undertook a development project that led to a product specifically designed for the leather industry, which has good fungicidal effectiveness, an acceptable toxicology/eco profile and competitive cost. This paper provides an overview of the performance characteristics of this new leather fungicide.
