Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch. Dextrin Glue is a liquid adhesive that is prepared by cooking to 200° F in water to form a solution which is then modified for tack, open time and various other properties. There are three main types of dextrin adhesives: white dextrins, canary (or yellow) dextrins and british gums.
Dextrin glue is often used as a packaging adhesive and also in the graphic arts industry, for example, in game-board manufacture. Dextrin glue is a water-based adhesive and is easily customizable in a variety of ways, including color.
All dextrin glues possess clean machining capability and excellent bonding properties to cellusic materials, which means they are made from a biofuel produced from wood, certain grasses, or other non-edible parts of plant life.
