Features & Benefits

Product Highlights
  • Deuteron® VT 819 is a natural biopolymer based on polysaccharides. Due to the glyoxal surface treatment the hydration properties of Deuteron® VT 819 are de- layed. This leads to an easy to use and easy to disperse product. Solutions based on Deuteron® VT 819 tolerate a wide temperature and pH range. At pH levels <2 and >12 depolymerisation and thus a decrease in viscosity can occur.
  • Deuteron® VT 819 is stable in anionic and non-ionic systems. In cationic systems it may come to incompatibilities. Deuteron® VT 819 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 behavior.
  • The product is compatible with most commonly-used binders and thickeners used in the coating industry.
