About Polysilazanes

What are polysilazanes?
Polysilazanes are polymers consisting of silicon, nitrogen, hydrogen and, in the case of organopolysilazanes, carbon. Such polymers can be considered either inorganic (perhydropolysilazanes) or organic (organopolysilazanes) in nature and have both silicon and nitrogen atoms in their backbone. Polysilazane-based coatings can be modified to make protective layer:
  • Hydrophobic coatings – water contact angle can be up to 120 degrees with OPSZ (Organic Polysilazane Resins)
  • Hydrophilic coatings – water contact angle smaller than 10 degrees with PHPS (Perhydropolysilazanes Resins)
 
Why use polysilazanes?
  • Pre-cursor for hybrid and ceramic materials
  • Melt-accessible to difficult to reach locations
  • Conducive to traditional processing options
  • Non-fugitive with high ceramic yield
  • Favorable release properties
  • Creep resistance
  • Corrosion resistance
  • Oxidation resistance
  • Excellent adhesion to most of substrates
 

Polysilazanes benefits

  • Excellent adhesion on most substrates – glass, polycarbonate, PMMA, PET, aluminum, steel, galvanized steel, stainless steel, silver, copper, brass, bronze, marble, varnishes, etc.
  • Excellent hydrophobic properties for Organic Polysilazanes
  • Excellent hydrophilic properties for Inorganic Polysilazanes (PHPS)
  • Attractive physical characteristics – high hardness, UV transparency, corrosion resistance, thermal durability and stability
  • Excellent candidates as binders for coatings in various environments – high temperature to extreme weather and chemical resistance
  • Contains inactivated sites that can activated to form a cross-linked network through the addition of heat or UV
  • Contains activated sites that can be cured through moisture-induced cross-linking at ambient (room) temperature
