ORMOCER®s as
bulk materials
ORMOCER® resins/composites (processing-relevant data)
  • Solvent-free resins/composites
  • Storable for up to several months
  • Resin rheology: 0.1 to 100,000 Pa•s at 25 °C, viscosity drops significantly when temperature rises
  • Curing by means of conventional polymerization or polyaddition reactions (thermal, photochemical and redox-initiated)
  • Processing (manual, fiber drawing, injection molding, casting, etc.)
