Diethoxypolycarbosilane is a
viscous liquid polymer that can be cured into solid at room
temperature by moisture from air. It can also form a sol-gel
material by reacting with water. Ethanol is a by-product from
curing or sol-gel reactions. The resultant coatings from
direct-air curing or sol-gel reactions can then be heated to
400°C
to achieve better mechanical properties. Either resulting
solid can be pyrolyzed to form a silicon oxycarbide by heating
to 1000°C.

Precursor for SiOxCy ceramic
Handling and
storage:
Store in tightly sealed containers. Keep away from heat,
sparks, and open "
ame. Material is moisture sensitive, store
in a cool dry place.
Safety:
Respiratory protection:
Do not breathe vapor or mists. Use NIOSH/MSHA
approved organic vapor/acid gas respirator.
A self-contained breathing
apparatus is required if the polymer is used at over 100°C
outside
a
ventilation
hood. Mechanical exhaust engineering controls required, or use
only in chemical
fume hood.
Protective Gloves:
Compatible chemical resistant gloves (Viton or Sliver Shield
are recommended).
Eye Protection: Other Protective Clothing/Equipment:
Do not get in eyes, on skin, or clothing. Safety
glasses/goggles, face shield (8-inch
minimum), and
chemical resistant clothing/apron should be worn. Emergency
shower
and eye bath should be available
