Features & Benefits

Product Highlights
  • Deuteron® SR 28 is a natural biopolymer based on polysaccharides. It is soluble in cold and hot water and results in pseudoplastic solutions. Solutions based on Deuteron® SR 28 tolerate a wide temperature and pH range. At pH levels < 2 and > 12 depolymerisation and thus a decrease in viscosity can occur.
  • Deuteron® SR 28 solutions tolerate the presence of up to 40 % of organic solvents such as alcohols or glycol ethers.
  • Deuteron® SR 28 is insoluble in pure organic solvents. Deuteron® SR 28 is stable in anionic and non-ionic systems. In cationic systems it may come to incom- patibilities.
  • Deuteron® SR 28 creates a strong structure viscosity. The viscosity decreases when the shear force is increased. It quickly returns to the base viscosity when the shear force is removed. This prevents settling of pigments and fillers and separation of the liquid phase during storage. It also makes application easier by stabilising the sagging behaviour. The product is compatible with most commonly-used binders and thickeners used in the coating industry.
