Anti-yellowing Silicone Curing Agent C-15
C-15 is a kind of peroxide system curing agent, the cured silicone by this agent are characterized
non-toxic and good anti-yellowing performance. Silicone raw material should be cured at high
temperature.
Note: This agent is inflammable and volatile. Please watch out during work time
Composition:
1,Anti-Yellowing Agent
2,peroxide
3,polysiloxane
Physical Properties :(Tested by KE-951U silicone rubber)
Appearance: Milk white or semi-transparent paste
Specific Gravity(g/cm³)(23℃): 0.9~1.0
Hardness(ShoreA) :49~51
Tensile Strength(Mpa): 10~13
Elongation(%): 500~530

This agent must be added by many times with a small quantity. If not, fewer electrostatic
spark and over heat from roller will cause material burning during the mixing time, The fire can
be put out by foam extinguisher.
Attention:
1. Avoid to contact with rust, heavy metal compound, metal salt, drying agent etc.
2. High vapour pressure agent easy to volatilize,must be kept in sealed when not in use.
3.The silicone rubber of mixed curing agent should be used up within 12 hours. Otherwise affect
the curing rate.
