Abstract

PURPOSE: A stable tannin-type curable adhesive composition having improved adhesiveness and water resistance, and a long pot life, comprising vegetable tannin, urea, formaldehyde, and water of specific composition.
CONSTITUTION: (A) 100 parts by wt.(solid content) of a vegetable tannin, e.g. mimosa, chestnut tannins, etc. is incorporated with (B) 30W300 parts by wt. of urea, (C) 1.5W4 moles per mole of the urea of formaldehyde, and water. The solid content is adjusted to 30 wt.% or higher.
EFFECT: Improved storage stability, long pot life, improved bond strength and water resistance.
USE: Plywood and particle board.
