Controlling viscosity, maintaining suspension stability, and achieving consistent binding are important requirements across industrial manufacturing. From water-based coatings and textile printing to welding electrode production, the choice of functional polymer can influence material behaviour and processing performance.
Scogin® and Protaweld® Alginate BioPolymers, are seaweed-derived polymers that provide thickening, binding, gelling, and water-retention functionality. These renewable biopolymers offer different formulation options for aqueous industrial systems and welding electrode manufacturing.
Alginates are naturally occurring polysaccharides extracted from brown seaweed. Their polymer structure consists of mannuronate (M) and guluronate (G) units, which influence viscosity and gel-forming behaviour. One distinctive property is their ability to form gels in the presence of calcium ions. This occurs through interactions between calcium and alginate chains, creating a water-retaining network.
Depending on the grade and formulation conditions, alginates can modify rheology, stabilise suspensions, form films, and bind. These properties make them useful wherever you need to control the consistency of water-based materials or structural cohesion.
The Scogin® and Protaweld® portfolios address different manufacturing challenges.

Welding electrode manufacturing |
Alginate selection depends on intended function and manufacturing conditions, not application category alone. For water-based formulations, key selection criteria include viscosity, hydration rate, dispersion behaviour, and gelation requirements. A textile printing formulation may require controlled paste consistency, while a water treatment application may prioritise floc formation and suspension behaviour. In welding electrode manufacturing, the focus shifts to binder strength, plasticity, and extrusion performance. The selected Protaweld® grade must provide the required coating characteristics while supporting consistent processing.
ChemPoint's industrial alginate portfolio provides grades with different characteristics, allowing manufacturers to evaluate their suitability against specific formulation and production requirements.
