BORACOL 20 - 2 is a wood preservative which is fungicidal and insecticidal in its preventative action and fungicidal when used as an eradicant.

BORACOL 20 - 2 is a clear solution of 20% Disodium octaborate tetrahydrate in propylene glycol. It is designed for use as a surface treatment in-situ building material to eradicate fungal attack and preserve against attack from both fungus and wood boring insects. It penetrates 3 - 5mm into the wood and establishes a reserve from where further penetration takes place (40mm in 2 years has been demonstrated).

Shelf life is 6 - 12 months in cool, dry conditions.
