Carbon-Based Chemical

LIFESPAN® has been treated with a solvent-based (non-aqueous), colorless, carbon-based, wood preservative (LOSP-Light Carbon-based Solvent Preservative). Three active ingredients (propiconazole, tebuconazole and permethrin) synergistically provide protection against a wide range of fungi, insects and rot:

  • Propiconazole and tebuconazole are EPA registered systemic fungicides, used widely to control mould and mildew in agricultural and horticultural applications. Together, they protect lumber from a wide range of wood destroying fungi.
  • Permethrin is an EPA registered insecticide used to protect wood against termites and borers. Permethrin is used in many agricultural, household and pharmaceutical applications.

This combination has been specifically formulated as an EPA registered wood preservative. It can be used to treat wood for use in American Wood Preservers Protection UC3A applications. The chemicals are virtually insoluble in water, remaining permanently in the wood and not leaching into the soil. The LOSP used in LIFESPAN® is non-corrosive to fasteners, so LIFESPAN® can be used with regular galvanized fasteners in exterior applications and any fastener type in interior applications.

The LOSP wood preservative, Vacsol® Azure, is manufactured and supplied in New Zealand by Arch Wood Protection (NZ) Limited, a wholly owned subsidiary of Arch Chemicals, Inc. of the USA.
