Protaweld® and Scogin® Alginates


Scogin® and Protaweld® Alginates are naturally occurring polysaccharide polymers that are extracted from brown seaweed that is harvested out of the Norwegian coast line.  Scogin® and Protaweld® are used in industrial applications as binders, thickeners, and gelling agents.  Alginates like Scogin® and Protaweld® are composed of two monomers: (1-4)-linked D-mannuronate (M) and l-guluronate (G).  In nature, alginate polymers consist of recurring G-G-G, M-M-M or M-G-M-G blocks.  The ratio of these blocks in the polymer dictates the polymer properties for example,  alginate polymers with higher G-block content exhibit higher gel strength.  Scogin® and Protaweld® Alginates offer a wide variety of functional properties that are useful in industrial applications, such as:

-Cold / hot water solubility
-Gelling capabilities triggered by the addition of calcium
-Rheology modification
-High water retention efficiency
-Improved suspension
-Water soluble film formation

The unique properties listed above make Scogin® and Protaweld® Alginates useful in a variety of industrial applications including welding rods, textile printing, paper, packaging, and water treatment.  Selection of the proper grade of Scogin® or Protaweld® for a particular application is based on viscosity & gelation requirements, speed of hydration, and desired shear required for dispersion.  View the commercially available grades of Scogin® and Protaweld® below for more details.
