Non-hazardous Components: Ingredient Name Concentration, % Silicone polymers 15-25% Hazardous Components: CAS # Ingredient Name Concentration, % EINECS# 79-01-6 Trichloroethylene 30-60 % 201-167-4 1330-20-7 Xylene 15-30 % 215-535-7 100-41-4 Ethyl benzene 5 - <15 % 202-849-4 NFPA Rating(estimated) Health 2; Flammability 1; Reactivity 1 HMIS: Health: 2; Flammability: 1; Reactivity: 1; Contact: 3
Potential health effects (acute and chronic):
Routes of entry:
Eye: Direct contact irritates slightly with redness
and swelling.
Health Hazards
(acute and chronic): The degree of injury depends on the duration
of exposure.
Inhalation: Vapors may injure lungs, blood, liver, kidneys,
and nervous system.
Skin: A single relatively short exposure irritates.
Repeated prolonged contact irritates seriously.
Over exposure may irritate internally.
Ingestion: Small amounts transferred to the mouth by fingers
should not injure. Swallowing large amounts will
injure seriously.
Signs and symptoms of exposure:
Prolonged over exposure may injure lungs, kidneys,
liver, blood, and nervous system and aggravate
existing eye, skin and respiratory disorders.
Medical condition aggravated by exposure:
Short vapor exposure may cause drowsiness and
irritate throat.
Routes of entry: Inhalation, ingestion or skin contact.
Carcinogenicity:
Not determined
Emergency and first aid procedures: Take proper precautions to ensure your own health and safety before attempting to rescue and providing first aid. These practices include avoiding all unnecessary exposure and removal of the material from eye, skin and clothing. Inhalation: If symptoms are experienced, move victim to fresh air, if symptoms persist, obtain medical attention. Medical assistance should be obtained at once. Eye contact: Wash eyes with clean low pressure water for fifteen minutes. Seek medical assistance without delay. After all, this is a leak sealant and one should not have curing silicone in their eyes. Skin contact: If the polymer should contact the skin, wipe off and wash with plenty of water. Ingestion: This route of exposure is not anticipated. However, cured silicone resins are not perceived to be highly toxic in the body. Nevertheless, get medical attention immediately. Do not induce vomiting. Prevent aspiration of liquid into lungs. Never give anything by mouth to an unconscious person.
Fire Extinguishing Media: Dry Chemical, water fog, foam, carbon dioxide, other Special Firefighting Procedure: Wear self-contained breathing apparatus due to thermal decomposition of products and protective clothing should be worn. Unusual Fire and explosion hazards: Vapors are heavier than air and can travel along the ground to remote areas. Fire And Explosion Hazard Data Flash Point............... 17.4°C (63°F) PM Closed Cup Flammable Limits in Air... Flammable limit in air, % by vol. (trichloroethylene) LEL (Lower Explosive Limit) : Unknown UEL (Upper Explosive Limit) : Unknown
Spill Response: Use absorbent material to collect and contain for salvage or disposal. Remove all sources of ignition and wear protective equipment. Use chemical worker goggles. use respiratory protection unless local exhaust ventilation is adequate or air sample data exposures are within TLV and PEL guidelines. Rubber or plastic gloves are recommended. Remove contaminated clothing and shoes as soon as practical and clean before reuse.
Precautions to be taken in handling and storing:
Keep container closed and away from heat.
Other precautions:
When processing at elevated temperatures, provide ventilation to
control exposures within OSHA and ACGIL limits. Aerosol or spray
applications may require added precautions. Evolution rate is
highest during the first few hours, then subsequently approaches
zero.
Do not store neat heat of flame or other source of ignition
(e.g. Electrical wiring or motors).
Other: Keep container tightly closed. Store in cool
dry well ventilated area.
Handling and Storage:
Do not store neat heat of flame or other source of ignition
(e.g. Electrical wiring or motors).
Use protective rubber or plastic gloves when handling to
avoid skin contact. Always use proper eye protection.
Keep protective clothing in good clean condition and clean
thoroughly after each use.
Engineering Controls:
Use only in well ventilated area in order to prevent the build up of
vapors or fumes.
Personal Protection:

product in aerosol form. Avoid breathing the vapors
of the product.
Skin: Use protective clothing such as long sleeves or a lab
coat.
Eye: Always use safety glasses, preferably chemical
goggles when using any form of this product.

Carcinogenicity:
Not determined
Exotoxicity:
Exotoxicity is expected to be low based the fact that solvents
evaporate quickly and the silicone polymerizes into an inert
substance with virtually no water solubility. No other information
is known on this topic.
Environmental Fate:
No information found in our selected references.
Bioaccumulation:
Not expected to occur.
Disposal considerations: All local, state, federal or other regulations concerning health and pollution should be reviewed to determine approved disposal procedures.
