Since the 15 th century, linseed oil has been extensively used in varnishes and oil-based house paints (Lazzari & Chiantore 1999).It has also been applied for treating wood and in manufacturing of linoleum, a floor covering made from mixture of natural materials, such asGet Price
Low-temperature oxidation | SpringerLink
Low-temperature oxidation is controlled by the nature of the oxide; whether it is a network former or a modifier. A period of fast, linear oxidation is followed by a slow logarithmic reaction whose rate, in turn, can increase if the oxide film crystallizes to form grain boundaries.
