Abstract
A cold-setting starch adhesive comprising the mixture of three different types of corn starch having widely different properties, i.e., high amylose corn starch having an amylose content of at least 50%, ordinary corn starch and waxy corn starch, in specific proportions. The adhesive shows excellent properties due to the effective combination of the outstanding properties of the individual types of starch.
