BORON BASED Preservatives - History

Active Dry Rot showing Fruiting Bodies

Compounds of Boron, known as Borates, have been mined since the 1800s and have been used to control insect pests for over 100 years.

By the 1940s borate formulations were being used to protect wood. Because they are water soluble, Borates diffuse into wood using the wood's own moisture (even 'air dry' timber has a moisture content of 12-15%) and they protect against termites, wood destroying beetles, carpenter ants and fungi, including Dry rot.

BORON - Inorganic Borate Compounds

SINGLE CHEMICAL - TRIPLE ACTION

TIMBER & MASONRY TREATMENTS

Introduction

Carpenter Kit Borons are fungicidal and insecticidal treatments manufactured from Inorganic Compounds of the Element Boron. They prevent insect attack and eradicate Dry rot in timber, being mobile in dry timber. They allow the use of the ZERO CUTBACK OPTION - no sound timber need be removed beyond the physically damaged zone. They also provide permanent protection, as the active ingredient does not break down or evaporate.

WORLDWIDE USE

Over 40 years of successful use in Europe, Australia, New Zealand and the USA. Used in dusting, foaming, spraying, brushing and pressure treatment applications. Other major uses include: glass production, detergent preparations, enamel and ceramic glazes.

PENETRATION

Even when applied in its most basic form, as a solution (up to 12.5% active) in water, Borates penetrate a minimum of 2-3 mm in 'DRY' timber and more, depending on the moisture content of the timber. In conjunction with Glycols, as gels and pastes (in concentrations of up to 78%) penetration increases dramatically. These more expensive products are designed for situations where deep seated decay requires high below-surface concentration of the active ingredient. This is not required, or desirable for normal Common furniture beetle spraying.

DURABILITY

Boron remains inert in the timber, providing protection long enough for Railtrack to have specified it for Railway Sleeper protection.

All 'Ultra Kit' products are supported technically with Method Statements, Specifications and a comprehensive Training Program. Please ask for our Training Brochure.

WOOD PRESERVATIVE AND BIOCIDE SAFETY

Use wood preservatives and biocides safely. Always read the label and product information Data Sheet before use.

Wear the correct safety equipment and keep unprotected people and animals out of the treated area for the statutory period given on the label.

All products have some hazards and the COSHH Regulations (Control of Substances Hazardous to Health) apply to ALL building repair and construction products that we sell, even Cement.

If in doubt consult us for free technical help. Take care not to contaminate soil, waterways or the environment with the product or the waste and packaging. These can be returned to us for disposal.

Avoid using any type of chemical in your home if any of the following are likely to come into contact with treated surfaces: babies, young children, asthmatics, pregnant women or those vulnerable due to ill health.

PROPOSED BORON RECLASSIFICATION - ongoing action by Rio Tinto Borax

Borax are currently appealing against the European reclassification of some Borates. We will advise you when we have a definitive ruling for the UK from the UK Authority, the HSE. Many of our Products will be unaffected. If they are reclassified, a warning label will only indicate a hazard to pregnant women if they chose to eat a significant quantity of high concentration Borate, an unlikely risk in our Industry. Long term testing of Borate Miners' health shows no related health hazards.

'Boron' is a generic term (more correctly used for the Element Boron) applied to a range of Boron Compounds known as Borates and sold under the names D.O.T., Timbor, Tim Bor and Borax, all made by the company U. S. Borax, of '20 Mule Team Train' fame.
