Product Description
Dextrin is a white, amorphous, odorless powder with a mildly sweet taste. It is slightly soluble in cold water, more easily soluble in hot water, and insoluble in ethanol and ether. When reacted with iodine, it produces a red coloration. Dextrin is extensively used as an adhesive in a wide range of industries, including pharmaceuticals, food processing, papermaking, casting, wallpaper production, labels, stamps, and adhesive tapes.

Product Application
Dextrin is widely applied as an adhesive in various industries, including pharmaceuticals, food, papermaking, casting, wallpaper production, labels, stamps, and adhesive tapes. When used as a tablet adhesive, it is required to dry quickly, spread evenly, bond rapidly, and remain soluble under moist conditions. In such applications, white dextrin or low-viscosity yellow dextrin products are commonly selected. For label and stamp adhesives, high viscosity and strong film toughness are essential, and white dextrin or British gum is suitable. In addition, dextrin is also used as a printing paste in textile printing and dyeing processes.
