Boron Family

boron-header      boron-plant     

Boron is one of nature’s best wood preservatives and is ideal for the protection of many types of wood products.  It is economical, easy to use and effective against a very broad range of decay fungi, moulds and insect pests that can infect wood.

arxada offer the industry leading range of boron based wood preservatives for solid wood and timber products used in appearance and structural applications. Our boron wood preservative family of products can be applied by simple dipping processes through to fully automated pressure impregnation processes.

Our Brands Include:

Brightener™ Solution

Treatment of certain hardwoods with boron can result in accumulation of tannin and other dark coloured extractives from the wood in the treatment solution which produces a darkened appearance of wood after treatment.  Addition of Brightener™ Solution can clean up discoloured boron treatment preservatives quickly by deactivating those extractives. This results in a fresher and cleaner appearance of the treated wood.
