Wood products used in exterior applications must be protected against biodeterioration. Traditionally, wood products used CCA or the older inexpensive organic biocides, but environmental, disposal and governmental regulations have resulted in a rapid and dramatic worldwide shift. This book covers the many steps involved in developing a wood preservative and gives overviews on modified wood, wood deterioration, worldwide trends in wood protections, and mold in homes.

The effective and lasting treatment of wood against insect and fungal attack grows in importance as forestry reserves decline and as cost increases feed through to the building trade and other timber users. At the same time, environmental pressures bear ever more heavily on the types of chemicals and processes employed in the preservation industry. This book records the proceedings of an international meeting arranged to address such issues. The 15 principal chapters are based upon papers by invited experts to a combined audience of preservation practitioners and non-specialists. The chapter sequence follows the logical pattern of the conference, beginning with a review of the biological threats to be contended. There follow historical and state-of-the-art accounts of aqueous, organic solvent and non-liquid treatment processes. Preservatives increasingly must meet international product and environmental standards, which along with the related test, analytical and quality control procedures, are described and referenced. Contributors from the wood preservation industry address a range of needs associated with cost, safety and performance efficacy, not neglecting a search for a better understanding of the finer chemical mechanisms involved. Remaining problems are outlined in strategies for further research and development. - Address a range of needs associated with cost, safety and performance efficacy - Problems are outlined in strategies for further research and development

NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT-- OVERSTOCK SALE -- Significantly reduced list price Wood preservatives are generally grouped into two categories: preservatives used for in-place field (remedial)treatment and preservatives used for pressure treatments.A limitation of in-place treatments is that they cannot beforced deeply into the wood under pressure. However, theycan be applied into the center of large wooden membersvia treatment holes. These preservatives may be availableas liquids, rods, or pastes. Pressure-treated wood has muchdeeper and more uniform preservative penetration thanwood treated with other methods. The type of pressuretreated wood is often dependent on the requirements of thespecific application. To guide selection of pressure-treatedwood, the American Wood Protection Association developedUse Category System standards. Other preservative characteristics, such as color, odor, and surface oiliness may alsobe relevant. Guidelines for selection and application of fieldtreatments and for selection and specification of pressure-treated wood are provided in this document.

An in-depth examination of deterioration caused by fungi and other microorganisms, Wood Microbiology explores the major damages to wood and wood products during growth, harvesting, storage, and conversion to finished lumber. The characteristics, causes, detection, effects, and control measures for wood damage are stressed. - Reviews characteristics, classification, and metabolism of fungi responsible for wood deterioration and discoloration - Examines the anatomical, structural, and chemical features of decay - Covers effects of decay on physical and structural properties of wood - Presents methods for preventing biodegradation and for preserving wood - Extensively classroom tested--suitable for a two-quarter or one-semester course - Each chapter contains a summary and detailed references

For decades chromated copper arsenate (CCA) was the primary preservative for treated wood used in residential construction. However, recent label changes submitted by CCA registrants will withdraw CCA from most residential applications. This action has increased interest in arsenic free preservative systems that have been standardized by the American Wood Preservers? Association. These include acid copper chromate (ACC), alkaline copper quat (ACQ), copper azole (CBA-A and CA-B), copper citrate (CC), copper dimethyldithio-carbamate (CDDC), and copper HDO (CX-A). All of these CCA alternatives rely on copper as their primary biocide, although some have co-biocides to help prevent attack by copper-tolerant fungi. These alternative treatments have appearance and handling properties‍?similar to those of CCA and are likely to be readily accepted by consumers. Prior studies indicate that these treatments release preservative components into the environment at a rate greater than or equal to that of CCA, but because their components have lower mammalian toxicity they are less likely to cause concern in residential applications. As the treated wood industry evolves, it is probable that a wider range of types and retentions of wood preservatives will become available, with the treatment more closely tailored to a specific type of construction application.

This handbook contains comprehensive information on more than 5000 trade names and generic chemicals and materials that are used in a broad range of formulations to prevent the contamination and decomposition of end products. Product degradation can be caused by exposure to oxygen, ozone, bacteria, molds, yeast, mildew, and fungi. The industries that depend on the proper selection of preserving chemicals and materials are diverse and include: plastics, elastomers, construction, paper/pulp, agriculture, textiles, paints and coatings, pharmaceutical, cosmetics, food, beverages.This handbook contains comprehensive information on a variety of preservatives available from major chemical manufacturers and can expedite the material selection process for chemists, formulators and purchasing agents by providing the answers to these questions:? Is the agent capable of inhibiting the detrimental effects of oxygen, ozone, or microbes to the extent necessary?? Is the agent's overall physical and chemical attributes compatible with the product or system being protected?? Can the agent remain stable under storage conditions and for the application requirements?? Is its safety in production and handling acceptable?? Does its level of toxicity meet environmental regulations?? Does it meet cost requirements?
