even in individuals who have not been shown to be previously sensitized. MATERIAL IS SEVERELY 

IRRITATING. It may not be advisable to induce vomiting. Possible mucosal damage may 

contraindicate the use of gastric lavage. 

5. FIREFIGHTING MEASURES

Flash point No test data available

Lower explosion limit no data available

Upper explosion limit no data available

Suitable extinguishing media:Use the following extinguishing media when fighting fires involving this 

material:

apparatus. 

Further information: Cool closed containers exposed to fire with water spray.

DO NOT permit water to enter containers.

Remain upwind.

Avoid breathing smoke.

Contain run-off.

Environmental precautions

WARNING: KEEP SPILLS AND CLEANING RUNOFFS OUT OF MUNICIPAL SEWERS AND OPEN 

BODIES OF WATER.

Methods for cleaning up

Evacuate personnel to safe areas.

Ventilate the area.

Floor may be slippery; use care to avoid falling.

Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).

Sweep up or vacuum up spillage and collect in suitable container for disposal.

Avoid all contact.

Avoid breathing vapor.

NOTE: Spills on porous surfaces can contaminate groundwater.

7. HANDLING AND STORAGE

Handling

Vapors can be evolved when material is heated during processing operations. See SECTION 8, 

Exposure Controls/Personal Protection, for types of ventilation required. 

Storage

Storage conditions: Avoid temperature extremes during storage; ambient temperature preferred. 

Store away from excessive heat (e.g. steampipes, radiators), from sources of ignition and from 

reactive materials. Material can burn; limit indoor storage to approved areas equipped with automatic 

sprinklers. Store out of direct sunlight in a cool place. Keep containers tightly closed in a cool, wellventilated place. Keep material dry. Moisture may affect product quality. 

Further information:

This material is a potential sensitizer.

See SECTION 8, Exposure Controls/Personal Protection, prior to handling.

Wash after handling and shower at end of work period.

CONTAINERS MAY BE HAZARDOUS WHEN EMPTY. Since emptied containers retain product 

residue follow all MSDS and label warnings even after container is emptied.

Improper disposal or re-use of this container may be dangerous and illegal. Refer to applicable local, 

state and federal regulations.

Persons susceptible to skin sensitisation problems or asthma, allergies, chronic or recurrent 

respiratory disease should not be employed in any process in which this mixture is being used.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Exposure limit(s)

Exposure limits are listed below, if they exist.

Component Regulation Type of listing Value

Rohm and Haas TWA 0.005 ppm

Rohm and Haas TLV-C 0.02 ppm

Exposure controls

Engineering measures: Use local exhaust ventilation with a minimum capture velocity of 100 ft/min. 

(0.5 m/sec.) at the point of vapor evolution. Refer to the current edition of Industrial Ventilation: A 

Manual of Recommended Practice published by the American Conference of Governmental Industrial 

Hygienists for information on the design, installation, use, and maintenance of exhaust systems. 
Page 5 of 10 Revision Date 03/28/2013

Protective measures: Facilities storing or utilizing this material should be equipped with an eyewash 

facility and a safety shower.

Individual protection measures

Eye/face protection: Use chemical splash goggles (ANSI Z87.1 or approved equivalent). 

Eye protection worn must be compatible with respiratory protection system employed. 

Skin protection

Hand protection: Chemical-resistant gloves should be worn whenever this material is 

handled. The glove(s) listed below may provide protection against permeation. 

(Gloves of other chemically resistant materials may not provide adequate protection): 

butyl-rubber Gloves should be removed and replaced immediately if there is any 

indication of degradation or chemical breakthrough. Rinse and remove gloves 

immediately after use. Wash hands with soap and water. 

Other protection: Use chemically resistant apron or other impervious clothing to 

avoid prolonged or repeated skin contact. Where splashing is possible, full chemically 

resistant protective clothing (e.g. acid suit) and boots are required. 

Respiratory protection: A respiratory protection program meeting OSHA 1910.134 and ANSI 

Z88.2 requirements or equivalent must be followed whenever workplace conditions warrant a 

respirator‟s use. None required if airborne concentrations are maintained below the exposure 

limit listed in Exposure Limit Information. Above the exposure limit: Wear a properly fitted 

NIOSH approved (or equivalent) self-contained breathing apparatus in the pressure demand 

mode, OR full-facepiece, airline respirator in the pressure demand mode with emergency 

escape provision.

11. TOXICOLOGICAL INFORMATION

Toxicological information on this product or its components appear in this section when such data is 

available.

Component:

Acute oral toxicity Low toxicity if swallowed.

Small amounts swallowed incidentally as a result of normal handling 

operations are not likely to cause injury; however, swallowing larger 

amounts may cause injury.

Swallowing may result in gastrointestinal irritation or ulceration.

Component:

Acute oral toxicity LD50 rat 4,130 mg/kg

Component:

Acute inhalation 

toxicity

LC50 mouse 6 Hour 0.1 mg/l

Component:

Acute dermal toxicity Prolonged skin contact is unlikely to result in absorption of harmful 

amounts.

Component:

Acute dermal toxicity LD50 rabbit > 9,400 mg/kg

Component:

Prolonged contact may cause severe skin irritation with local redness 

and discomfort.

Component:
Page 7 of 10 Revision Date 03/28/2013

Eye irritation Eye irritation

May cause severe eye irritation.

May cause moderate corneal injury.

Vapor may cause eye irritation experienced as mild discomfort and 

redness.

Component:

Sensitisation May cause sensitization by skin contact.

Skin contact may cause an allergic skin reaction.

Animal studies have shown that skin contact with isocyanates may play 

a role in respiratory sensitization.

Component:

Sensitisation May cause sensitization by inhalation.

May cause allergic respiratory reaction.

Reexposure to extremely low isocyanate concentrations may cause 

allergic respiratory reactions in individuals already sensitized.

Asthma-like symptoms may include coughing, difficult breathing and a 

feeling of tightness in the chest. Occasionally, breathing difficulties may 

be life threatening.

Effects may be delayed.

Component:

Subchronic toxicity Based on available data, repeated exposures are not anticipated to 

cause additional significant adverse effects.

Component:

Carcinogenicity: An oral study in which high doses of TDI were reported to cause cancer in 

animals has been found to contain numerous deficiencies which compromise the validity of the 

study. TDI did not cause cancer in laboratory animals exposed by inhalation, the most likely route 

of exposure. 

Component:

Reproductive toxicity

In animal studies, TDI has been shown not to interfere with reproduction. 

Component:

Teratogenicity

TDI did not cause birth defects in laboratory animals. Slight effects were observed in the fetus but only 

at doses which caused toxic effects to the mother. 

Component:

Mutagenicity

In vitro genetic toxicity studies were negative in some cases and positive in other cases. Animal 

genetic toxicity studies were negative. Results of a Drosophila study were reported to be weakly 

positive; however, these positive findings are believed to be due to degradation of TDI in the 

solvent delivery vehicle.

Biodegradability

In the aquatic and terrestrial environment, material reacts with water 

forming predominantly insoluble polyureas which appear to be stable.

In the atmospheric environment, material is expected to have a short 

tropospheric half-life, based on calculations and by analogy with related 

diisocyanates.
