What is methyl soyate?
SoyGuard® is formulated with methyl soyate, a natural solvent and oil that absorbs deeply into wood providing superior protection from degradation. In addition to the polystyrene barrier provided by our products, the methyl soyate acts as a sealer, supplying additional surface protection for wood from water damage.
Methyl soyate is a soy methyl ester derived from soybean oil. It has numerous environmentally friendly and worker friendly properties and characteristics. It is lower in toxicity than most petroleum derived solvents. It is readily biodegradable. It has a very high flash point, and a low level of volatile organic compounds (VOC) - less than 0.4 lbs/gallon. It is also a non-irritant to eyes or skin. It is NOT classified by the US Environmental Protection Agency as a hazardous air pollutant, an ozone depleting chemical, or a volatile organic compound.
