Systems and methods are provided for treating products containing wood fibers to provide protection against wood destroying organisms and fire, and resistance against leaching of the preservative from the wood by water in exposed environments such as exterior applications. The methods involve applying to a substrate a first aqueous composition containing a boron compound, a source of zinc, and ammonia, followed by application of a second aqueous composition containing an alkali metal silicate. T...

A process for preparing coated nanoscale quinacridone pigment particles, includes providing a first solution containing a surface additive compound in an acid; adding a quinacridone pigment precursor or crude quinacridone pigment into the first solution and causing the surface additive compound to coat formed nanoscale quinacridone pigment particles; and adding the first solution and coated nanoscale quinacridone pigment particles into a second solution containing deionized water to form a third...
