Chromated copper arsenate (CCA) for years was the most commonly used chemical to give wood decay resistance, for wood intended for use in construction. Other preservatives used are amine copper quat (ACQ), copper boron azole, copper azole (CA), acid copper chromate and copper citrate. An alternate category of chemicals are borate-based. Sodium borate and zinc borate are two available compounds. CCA, ACQ,CA and sodium borate are applied by pressure treatment.

Dimension lumber and plywood are available treated with CCA or borate. OSB treated with borate and CCA-treated Parallam are also available. Glulam can be effectively treated with oil-based preservatives, but these are not suitable for use in buildings. Glulam and LVL are very difficult to pressure-treat, however, it may be possible to treat these products with borate during production as with borate-treated OSB currently available commercially.

The wool has been cleaned with a mild soap and water solution and rinsed in hydrogen peroxide. No chemicals have been added.

No. Properly used off-the-shelf waterproofing products and wood stains will have no adverse effects on the system.

Wood products for construction are typically treated in a factory, using a pressure process. The product is loaded into a vessel, then the vessel is filled with a water solution containing the preservative chemicals. The vessel is pressurised to force the solution into the wood. Most dimension lumber can be treated this way, as well as plywood and Parallam. Other composite products are hard to pressure-treat, for example, OSB, LVL and glulam.

Yes. But be cautioned that Shingle Shield is designed specifically for use with three tab shingles. The installer assumes complete responsibility as to how to attach the product to a wood roof. The primary objective is to have rain water run over Shingle Shield, then onto the areas affected by fungus, moss, or algae.

Yes, but be aware of woods that have an inherent high level of natural oils, such as teak and kiaat. With milk paint being a water-based paint, there is an expected aversion to oil, including naturally oily woods and pre-treated timber.

When constructing a raised bed, treated wood is often used as it is resistant to rot. The most commonly available treated wood is impregnated with a CCA (chromated copper arsenate), often known as Wolmanized wood. To treat wood throughout, CCA is applied under very high pressure. This treatment fixes the CCA inside the wood, greatly reducing to potential for loss at the surface. However, with time, small amounts of arsenic, chromium, and copper will leach out to the surrounding soil.

Accepta’s advanced boiler water treatment chemicals include scale and corrosion inhibitors, antifoams, sludge conditioners and more, used for improving the efficiency of steam and other boiler systems.

Accepta’s cooling water treatment chemicals are used to protect systems from the four problems suffered by such systems namely, scale, corrosion, suspended solids and bio-fouling. These chemicals help improve system efficiency and maintain safe working conditions within the cooling system itself.

Tarceva is approved as monotherapy, meaning it is used without chemotherapy, for second- and third-line treatment of advanced NSCLC patients. This means that your doctor can prescribe Tarceva after one chemotherapy regimen has not worked.

The tricyclic antidepressants can provide relief for some neuropathic pain, particularly pain that the patient describes as burning, tingling, numb, painful to a light touch or like pins and needles. Amitriptyline (Elavil), desipramine (Norpramin), and nortriptyline (Pamelor) are the most commonly used. Start with 25mg per day. Typically, these medications are increased by 25mg every 3 days until the patient has pain relief or encounters unacceptable side effects.

Water, Butanol, and Acetone are often used in the extraction process of OPCs, but evaporate before the process is complete. OPCs are 100% natural.

Once the coconut meat is transported to the local oil factory it is crushed, heated and pressed. Only one single pressing is performed. No chemicals are used during the entire production and the oil is never mixed with a lesser quality second pressed oil. This traditional process is a unique particularity of the local Tahiti oil plant.

All of the components in the MagicTan tanning solution have been used in cosmetics and food products for decades. These components are approved for use on the skin and are considered safe.

No chemicals are used in vapor steam cleaning. We do need to stress that we still advise using a natural surfactant on heavily soiled and stained carpeting. Also some bathrooms may need some extra surfactant help. Vapor steam cleaning is best used in tiling bath surrounds not fiber glass. Our testing of residential vapor steam cleaners showed us that you will find steam alone will not be sufficient for these kinds of cleaning challenges.

No. All filters contain natural elements such as salt, resin beads and carbon sediment and are environmentally safe.
