D-Gel – Solvent for Hydrophobic Filler (Hydrophobin) Removal from Fiber Optic Cores


Product description:
MENDELEEV research and production company has developed and put into production Turbo-Reactive Solvent grade D, an equivalent (substitute) of imported D-gel. It is designed to degrease optic parts and remove hydrophobic filler (hydrophobin) from fiber optic cores in the course of assembly.

  • Low volatility allows to minimize solvent consumption during degreasing operations or hydrophobin removal;
  • Safe for PVC plastics and optical fiber;
  • Excellent detergent properties in relation to oils, fats, soot and smut;
  • Efficiently removes silicone hydrophobizated fillers during fiber optic cable stripping;
  • Does not conduct electrical current (dielectric);
  • Flashpoint is above 60°С, not a HIL;
  • Does not cause corrosion of metal surfaces (ferrous and non-ferrous metals) and contains no aggressive components;
  • Does not contain chlorinated hydrocarbons that destruct the ozone layer;
  • Has water displacing properties and is suitable for wet surface cleaning.
