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.
