           Section 11 -- TOXICOLOGY INFORMATION
-----------------------------------------------------------------------------
CHRONIC HEALTH HAZARDS
   No ingredient in this product is an IARC, NTP or OSHA listed carcinogen.
May cause an allergic skin reaction. Suspected of causing cancer. Although the 
carbon black (CAS# 1333-86-4) is encapsulated by the silicone sealant, prolonged 
overexposure to carbon black dust causes lung fibrosis. Although the titanium 
dioxide (CAS# 13463-67-7) is encapsulated by the silicone sealant, prolonged 
overexposure to titanium dioxide dust causes tightness pain in the chest, 
coughing and difficulty breathing.  The curing vapor, Methyl Ethyl Ketoxime 
(CAS# 96-29-7), may cause drowsiness, injure blood, liver and may irritate or 
harm nose, throat, lungs and eyes. Direct contact with eyes will irritate. 
Direct contact with skin may irritate.
