Capability and application£ºIn addition to being colorless, tasteless, nontoxic and uneasy to volatilize, the product also is high in flash point, low in solidifying point, good in viscosity-temperature characteristics and defoaming property but worse in oil solubility, which will affect deflation property of oil products. So it is the defoaming agent of oil products with wider application at present, besides, it also can be used as release agent and others.
