【Transportation and Storage】
The direct addition of the product to water causes the formation of lumps . Lumping results from incomplete wetting of the individual powder particles . Only the powder in contact with water dissolves and the formed gelatinous membrane prevents the remaining powder from dissolving , causing a delay in the dissolution time . The following three methods are recommended for dissolution without forming lumps . The most convenient method should be chosen according to the purpose of your application.
