many tropical plants produce the gum sap for this adhesive sizing ingredient. It comes in hard chip form, but will become gelatinous when mixed with water, a popular sizing agent, obtained from certain varieties of Astragalus, a ‘gum’ or mucilaginous substance obtained from several species ofAstragulus, by natural exudation or incision, in the form of whitish strings or flakes, only partially soluble in water. Used in medic, sarnaneb kummiaraabikuga, kuid on eriti tugeva sidumisvõimega. Kasutatakse limainene ja emulsiooni tekitajana tekstiili- ja värvitööstuses ning farmaatsias.
