Resulting Properties

The above formulation is for a dextrin that is commonly used for winding paper tubes. It has improved wet tack in which the bond remains firm immediately after being established. This adhesive also has fast drying time and good strength to resist crushing.

Dextrin adhesives are readily available, low in cost, and easy to apply from water dispersion. They are considered to be the least expensive class of paper packaging adhesive. Formulated dextrin adhesives can be applied hot or cold.

Also:

Improved wet tack
Controlled degree of penetration
Thixotropic properties that eliminate stringiness and provide good adhesion
Fast drying time
Greater strength to resist crushing
