ALGIN is a water-soluble polysaccharide and gives viscous colloidal solution.

Sodium alginate has a strong affinity with water and care is required to achieve a homogeneous aqueous solution.

It’s most important to first prepare uniform aqueous solution of ALGIN before it is utilized as a thickening agent, gelling agent, etc.

Poor dispersion in water will occur if sodium alginate is added too rapidly, producing pasty, floury lumps wetted only on the outside.

Alginate are all soluble to cold & hot water, and generate viscous aqueous solution with long-flow properties

Preparation print sotck paste:

Put sodium alginate into water, stirring with high-speed stirrer until the viscosity rises to a stable state. Lay the stock paste aside for several hours, let it dilate completely. Stir for a while and then the stock paste is ready for using.
