<strong>TRU</strong> <strong>CORE®</strong> PROCESS PROPERTIES<br />
�� Chemically based<br />
�� Rapidly drives preservatives,<br />
insecticides into wood <strong>and</strong> wood<br />
composites<br />
�� Uses minimal amount <strong>of</strong> water<br />
�� Applied by dip or in-line in line spray<br />
(60-65 (60 65° C)<br />
�� Full penetration achieved after<br />
12-24 12 24 hour activation period<br />
�� Can be accelerated using<br />
vacuum or pressure<br />
Wood <strong>for</strong> Life ®<br />
Patented & Patents Pending

<strong>TRU</strong> <strong>CORE®</strong> PROCESS COMPONENTS<br />
�� Water<br />
�� Non-volatile Non volatile polar carriers<br />
(TANOs)<br />
�� Wood preservatives <strong>and</strong><br />
insecticides (carbon based<br />
– most are compatible)<br />

<strong>TRU</strong>-<strong>CORE®</strong> <strong>Process</strong> Advantages<br />
� Completely penetrates:<br />
- engineered woods <strong>and</strong> panels like OSB, plywood, <strong>and</strong> LVL<br />
- “untreatable” woods like SPF <strong>and</strong> Douglas fir<br />
- heartwood <strong>and</strong> sapwood<br />
� No re-drying after treating Radiata pine <strong>and</strong> other easily “wettable” wood<br />
� No damage to wood strength or surface appearance<br />
� No volatile solvents or harmful chemicals<br />
� Easily adaptable to many wood processing plants <strong>for</strong> “in-line” or “batch”<br />
treatment<br />
� Can be used to carry many types <strong>of</strong> protective elements into the center <strong>of</strong> wood<br />
products:<br />
- fungicides<br />
- insecticides<br />
- mold inhibitors<br />
- water repellents

Conclusions<br />
<strong>TRU</strong>-CORE<br />
<strong>TRU</strong> <strong>CORE®</strong> <strong>Process</strong>:<br />
�� Can be used to successfully treat previously<br />
“untreatable untreatable” wood species (White Baltic<br />
Pine, Red Pine, Douglas fir, SPF, etc.).<br />
�� Can be used to successfully treat E-Wood E Wood<br />
(LVL, OSB, etc.) without solvents <strong>and</strong><br />
without impairing appearance or mechanical<br />
properties.
Conclusions<br />
<strong>TRU</strong>-CORE<br />
<strong>TRU</strong> <strong>CORE®</strong> <strong>Process</strong>:<br />
�� No re-dry re dry needed when treating Radiata<br />
pine <strong>and</strong> other easy-to easy to-treat treat species.<br />
�� Three independent labs demonstrate<br />
Permethrin penetration to the core <strong>of</strong> treated<br />
lumber <strong>and</strong> engineered wood.
