Abstract
PURPOSE: An inexpensive water-resistant composition, obtained by incorporating an aqueous solution containing starch or a derivative thereof essentially with specific starch derivative and an isocyanate compound with low pollution, and suitable particularly for wood adhesives.
CONSTITUTION: A water-resistant composition obtained by incorporating 100pts.wt. aqueous solution containig starch and a derivative thereof, e.g. wheat, preferably in a concentration of 0.5W40wt% with 1W50pts.wt. aldehyde starch having two or more aldehyde groups in one molecule or a derivative thereof, e.g. dialdehyde starch, and further 1W50pts.wt. isocyanate compound having two or more isocyanate groups in one molecule, e.g. tolylene disocyanate. The addition of 10W100pts.wt. aqueous latex, e.g. natural rubber latex, based on 100pts.wt. aqueous solution of the starch further improves the effect.
