Wood treatment designed for maximum solubility

Tim-bor® is a high-performance borate wood preservative that has been specially designed to provide the highest concentration of boron at the maximum possible solubility and rate of dissolution in water. Wood treated with Tim-bor can be used for a variety of purposes, such as trussed rafters, studding, cladding, and exterior joinery.

What can Tim-bor do for your process?

Tim-bor has a well-known and proven record of performance in the United States, Southeast Asia, Australia, and New Zealand. The product’s performance has been demonstrated by independent laboratory and field studies carried out by universities and government testing facilities around the world. (The use of Tim-bor varies according to working requirements and country- or market-specific product labels.)

Benefits of Tim-bor for wood protection

Safety: Tim-bor combines a broad spectrum of efficacy and low acute mammalian toxicity. The product has proven efficacy against wood decay fungi, wood boring beetles, and termites. In addition, it contains no organic or heavy-metal components or organic solvents.

Ease of use: You can apply Tim-bor as a pretreatment to dry (via vacuum-pressure processes) or green (via vacuum-pressure processes or dip diffusion) timber. The ability to treat green timber successfully and the subsequent diffusion of borates in wood enables penetration of species that are known to be difficult to treat, such as Douglas fir, spruce, and many hardwoods.

Beautiful results: Wood treated with Tim-bor retains its natural appearance and strength. Tim-bor wood treatment has little or no effect on ferrous metals, plastics, rubber, putties, bituminous solutions, other sealants, or primer paints.
