3. HAZARDOUS IDENTIFICATION:
Warning! Color: Pinkish tint; Form: Viscous Liquid; Odor: Negligible; May cause respirator tract irritation; Inhalation may cause nausea
or dizziness; May cause eye irritation; May be harmful if swallowed; Irritating gases/fumes may be given off during burning or thermal
decomposition.
Potential Health Effects:
Route of entry…………………: Inhalation; skin contact; skin absorption; eye contact
4. Human Effects and Symptoms of Overexposure:
Air monitoring conducted during the curing of this product has shown that acrolein and acetaldehyde vapors can be generated; if curing occurs
in an unventilated area exposure limit for acrolein could be exceeded. The following health effects include signs and symptoms associated with
overexposure to acrolein and acetaldehyde.
Acute Inhalation………………..: Acrolein vapors cause severe respiratory and eye irritation. Symptoms of overexposure include lacrimation,
a burning sensation in the throat, cough, chest discomfort and cyanosis (bluish discoloration of earlobes, lips and fingernails due to lack of
oxygen in the blood). The tlv is designed to minimize irritation. Acetaldehyde vapors cause respiratory and eye irritation. The irritant effects
include cough and burning sensation in the nose, throat and eyes. High concentrations can cause central system depression.
Chronic Inhalation…………….: None known.
Acute Skin Contact……………: Based on animal testing (see animal toxicity section), this product is not expected to be a skin irritant.
Chronic Skin Contact…………: None known.
Acute Eye Contact…………….: Based on animal testing, eye contact with liquid, aerosols and vapors of this product are not expected to cause
eye irritation. However, eye contact with acrolein and acetaldehyde vapors (which can be generated during curing) at concentrations above
their respective tlv’s can cause redness, tearing and swelling of the eyes.
Chronic Eye Contact………….: None known.
Acute Ingestion………………..: Can cause irritation in the mouth, stomach tissue and digestive tract.
Chronic Ingestion……………..: None known.
Carcinogenicity NTP………….: Not listed.
IRAC …………………………..: Not listed.
OSHA ………………………….: Not regulated.
5. MEDICAL CONDITIONS:
Aggravated by Exposure……..: Respiratory disorders may be aggravated by exposure to acrolein and acetaldehyde vapors.
Exposure Limits………………: Not established for product as a whole, refer to section 2 for exposure limits of hazardous constituents.
6. FIRST AID MEASURES:
First Aid For Eyes…………….: Flush with clean, lukewarm water (low pressure) for at least 15 minutes occasionally lifting eyelids. Obtain
medical attention.
First Aid For Skin…………….: Remove contaminated clothing. Wash affected areas thoroughly with soap and water. Wash contaminated
clothing before reuse.
First Aid For Inhalation……..: Move to an area free from risk of further exposure. Administer artificial respiration or oxygen if needed.
Obtain medical attention immediately.
First Aid For Ingestion………: DO NOT INDUCE VOMITING. DO NOT GIVE ANYTHING BY MOUTH TO AN UNCONCIOUS PERSON.
Consult physician.
7. FIRE FIGHTING MEASURES:
Flash Point……………………: 98 F (36.6 C) Pensky-Martens Closed cup (astm D-93)
Flammable Limits……………: (UEL)(%): 6.1 Styrene
(LEL) (%): 1.1 Styrene
Extinguishing Media ………..: Dry chemical; Carbon dioxide; Foam; Water.
Special Fire Fighting Procedures: Full emergency equipment with self-contained breathing apparatus should be worn by firefighters. During
a fire thermal decomposition and combustion may generate irritating and toxic gases and aerosols.
Unusual Fire/Explosion Hazards: Closed container may explode when exposed to extreme heat. Use cold water spray to cool fire-exposed containers
to minimize risk of rupture.
8. ACCIDENTAL RELEASE MEASURES:
Spill or Leak Procedures……: Evacuate non-essential personnel. Remove all sources of ignition and ventilate the area. Dike or impound
spilled material and control further spillage if feasible. Notify appropriate authorities if necessary. Cover spill with sawdust, vermiculite,
Fuller’s earth or other absorbent material. Collect material and place in a clean empty drum for disposal. Utilize recommended protective
equipment.
9. HANDING & STORAGE:
Storage Temperature (min/max.): 41 F (5 C) / 68 F (20 C)
Shelf Life………………………..: 6 Months
Special Sensitivity………………: Heat, light, moisture.
Handling/Storage Precautions…: Stored in closed containers and in the dark at temperatures less than 68 F (20 C). If organic peroxide
curing agents are used, mixing with pure accelerators can cause decomposition with explosive force. One material
must be thoroughly dispersed in the resin before the second is added.
10. PERSONAL PROTECTION:
Eye-protection Requirements……: Splash goggles, safety glasses or face shield. Contact lenses should not be worn.
Skin Protection Requirements…..: Permeation resistant gloves.
Ventilation/Respiratory Requirement: Exhaust ventilation sufficient to keep the airborne concentrations of acrolein and acetaldehyde below
the appropriate TLV’s during curing of coating system must be utilized. Exhaust air may need to be cleaned by scrubbers & filters to reduce
environmental contamination. Curing ovens must be ventilated to prevent off-gases from entering the workplace.
