What is the difference between old-fashioned stinky oil-based wood stain and BRODA ® natural oil water borne stain? First, we use water, not harsh solvents to carry the oils into the wood. But the oils we use are an important part of the picture, too.
Rather than use petrochemical-based oils that must be drilled or mined and refined, we use a combination of oils created by plants, using good clean sunlight.
Tung oil is pressed from the seed from the nut of the tung tree (Vernicia fordii). It is a drying oil, so it hardens upon exposure to air. The tung oil coating is transparent and plastic-like, yet permeable to water vapour. Tung oil is believed to have been used in ancient China and appears in the writings of Confucius from about 400 B.C.
Linseed oil (pictured above) comes from the dried, ripened seeds of the flax plant (Linum usitatissimum, Linaceae). Linseed oil is also a drying oil, which shrinks little upon hardening. Linseed oil soaks into microscopic pores of the wood, leaving a smooth surface that shows off the grain.
Both of these oils are generally considered to be non-toxic, though they can be irritants and generate allergic reactions in certain individuals.
Other water-borne oil stains contain ingredients such as aliphatic hydrocarbons, xylene, and ‘petroleum hydrocarbon’. By working with low-VOC and low-toxicity oils and other ingredients, the BRODA ® team has created a long-lasting beautiful product that protects much more than just wood.
