( fine powder )
Dextrin is used as a water
soluble glue, as a thickening agent in food processing, and as a binding
agent in pharmaceuticals. In pyrotechnics, it is added to colored fire
formulas, allowing them to solidify as pellets or "Stars".
Typically 5% to 7% (by weight) of Dextrin is added to colored fire
formulas allowing them to be pressed, rolled, or cut into Stars.
Drying problems begin to occur in Stars when
the Dextrin content exceeds 10%.
