The PTI preservative imparts very little color to the wood. Producers generally add a color agent or a trace amount of copper solution so as to identify the wood as pressure treated and to better match the color of other pressure treated wood products. The PTI wood products are very well adapted for paint and stain applications with no bleed ...
The chromium acts as a chemical fixing agent and has little or no preserving properties; it helps the other chemicals to fix in the timber, binding them through chemical complexes to the wood's cellulose and lignin. The copper acts primarily to protect the wood against decay, fungi, and bacteria, while the arsenic is the main insecticidal ...

The copper in ACQ treated wood accelerates corrosion of galvanized steel fasteners (such as nails and screws) 10 times or more in comparison with CCA-treated wood. Stainless steel (AISI 316) is not affected. [7] Aluminium and Galvalum fasteners should be avoided. [8] One should use fasteners made of hot-dipped galvanized steel, copper, or ...
The "Bethell process"—or as it later became known, the full-cell process—involves placing wood to be treated in a sealed chamber and applying a vacuum to remove air and moisture from wood "cells". The wood is then pressure-treated to imbue it with creosote or other preservative chemicals, after which vacuum is reapplied to separate the ...
Koppers Carbon Materials and Chemicals are used in the production of a variety of manufactured goods including aluminum, steel, plastics, resins, treated wood, and rubber products. These products also increase the durability and extend the life of products such as railroad ties, utility and transmission poles, and marine pilings. [ 9 ]
