Abstract
Although borates have been recognized as desirable for use in wood-based articles because of their preservative properties and low toxicity, it has not until now been possible to make effective use of them. A lignocellulosic e.g. wood-based composite article in accordance with the present Invention includes a low solubility borate compound which is mixed with the lignocellulosic furnish, resin adhesive, and a flow agent, the resultant mixture being pressed into a mat and cured. The low solubility borate can be used in a quantity from about 1% to 10% by weight of the furnish. Suitable flow agents are polyethylene glycol and glycerol in the amount of 0.4% to about 4% by weight of the furnish.
