Wespine Blue: General Attributes
Wespine Blue Treated Framing Timber is Deemed to be Resistant Against the Most Common
Termites and European House Borers in Australia.
Specifically Wespine Blue is approved for protection of framing and construction timber
in H2 - F applications (interior and protected from direct weather and moisture) against
attack by the major pest termite species such as Coptotermes spp, Schedorhinotermes and
Cryptotermes. However Wespine Blue is not approved at this time for protection of
timber against Mastotermes darwiniensis and Wespine Blue treated timber is deemed not to be
termite resistant in regions north of the Tropic of Capricorn.
Wespine Blue Has Been Exhaustively Tested and Researched
Extensive testing on the effectiveness of Wespine Blue treatment against termites
has been carried out for over three years in four
locations throughout Australia. The organisations conducting this test work
are respected and accredited testing
service providers, specifically the CSIRO Division of Forest Products,
State Forests of NSW and the Queensland Department of Primary Industries
Forest Research Laboratory. This testing has supported registration by the
APVMA (formerly the NRA), Australian Standards and complementing State
Legislation. Other attributes of the treatment and the treated timber have
been examined and reported by suitably qualified agencies or companies.
Wespine Blue is Suitable For a Range of Timber Sizes
It is Koppers Arch position that the efficacy of an envelope treatment has to be
evaluated in comparison to the overall cross section size of the treated timber. Thus,
the use of an envelope treatment over a large size timber section may not be an
appropriate combination. This assessment is based on risk analysis of the percentage of remaining
sound timber section if the untreated timber section was destroyed. At this time
Wespine Blue is suitable for treatment of any available timber sizes, up to 300 x 45, covering the great
majority of light framing requirements.
Wespine Blue Preservative Fluid is a Low Hazard Material
The treatment fluid is a solution of permethrin in a combination of oils including
natural vegetable oils and other additives that have special rheological properties to
allow the envelope penetration of wood. The application system of dipping or flood
immersion in an autoclave does not result in hazardous mists or fumes. The treatment
fluid has been specifically designed to be suitable for use in close proximity of a
wood processing plant and other machinery. The Iow potential for environmental work
site hazard or occupational exposure has been verified by two studies. Not rated as
flammable (flash point 77° C - combustible liquid class C1), Low VOC content « 7% w/w
according to EU definitions), Low skin irritation potential from contact with treatment
fluid or treated wood (permethrin content in product < 0.4%wlv).
