– Low Viscosity (7-20 mPa\u00b7s): Good fluidity, suitable for thin-film coating, taste masking coating, and fast-release micro pellet coating.\u200b<\/p>\n\n\n\n

– Medium Viscosity (45-100 mPa\u00b7s): Universal pharmaceutical grade, balanced film strength and permeability, ideal for standard sustained-release coating and common matrix tablets.\u200b<\/p>\n\n\n\n

– High Viscosity (150-300 mPa\u00b7s): Ultra-high barrier and toughness, applied to long-acting sustained-release skeletons and microcapsule wall materials for ultra-slow drug release<\/p>\n\n\n\n
