SECTION 1.  CHEMICAL IDENTIFICATION ---------------------------------------------------------


CHEMICAL NAME:         Organic Solvent Solution

TRADE NAME:                 SU-8 Developer

PRODUCT #:                      Y020100


SECTION 2.  COMPOSITION-----------------------------------------------------------------------------



INGREDIENTS:                 1-Methoxy-2-propanol acetate (CAS: 108-65-6), 98-100%

                                             Synonym: propylene glycol monomethyl ether acetate

                                             2-Methoxy-1-propanol acetate (CAS: 70657-70-4), 0-2%


SECTION 3.  HAZARD DATA----------------------------------------------------------------------------


INFLAMMABILITY:        Moderately combustible liquid.

SKIN CONTACT:              No significant signs or symptoms indicative of any health hazard are expected to occur as a result of skin contact. Possible systemic toxicity by skin absorption.

EYE CONTACT:                May cause moderate irritation, including burning sensation, tearing, redness or swelling.

INGESTION:                      Ingestion may cause gastrointestinal discomfort with any or all of the following symptoms: nausea, vomiting, lethargy, or diarrhea.

INHALATION:                  Prolonged overexposure to either vapor or mist may cause coughing, shortness of breath, dizziness and drunkenness.

MUTAGENICITY:            No data available.

CARCINOGENICITY:       Not listed in NTP, IARC, or OSHA as a carcinogen.

TARGET ORGANS:          Eyes, mucous membranes


SECTION 4.  FIRST AID MEASURES-------------------------------------------------------------------


INHALATION:                  If overcome by exposure, remove victim to fresh air immediately. Give oxygen or artificial respiration as needed. Obtain emergency medical attention. Prompt action is essential.

INGESTION:                      If large quantity swallowed, give lukewarm water if victim completely conscious/alert. Do not induce vomiting. Risk of damage to lungs exceeds poisoning risk. Obtain emergency medical attention.

SKIN CONTACT:              Remove contaminated clothing as needed. Wash thoroughly with soap and water. Flush with lukewarm water for 15 minutes. If sticky, use waterless cleaner first. Seek medical attention if discomfort persists.



EYE CONTACT:                Immediately flush the eyes with large amounts of clean low-pressure water for at least 15 minutes, occasionally lifting the upper and lower lids. If pain or irritation persists, promptly obtain medical attention.


SECTION 5.  FIRE FIGHTING MEASURES-----------------------------------------------------------



MEDIA:                                       Water spray, dry chemical, carbon dioxide, or alcohol-resistant foam.


PRECAUTIONS:                         Do not enter fire area without proper protection. Wear positive pressure self-contained breathing apparatus (SCBA). Fight fire from a safe distance/protected location.


EXPLOSION HAZARDS:          Heat may build enough pressure to rupture closed containers. Use water spray/fog for cooling.


SECTION 6.  ACCIDENTAL RELEASE PROCEDURES -------------------------------------------



PROCEDURES & SAFETY:       Wear appropriate protective gear for the situation. See Personal Protection information in Section 8.


OF SPILL:                                    Absorb with an inert absorbent. Sweep up and place in an appropriate closed container (see Section 7). Clean up residual material by washing area with water. Collect washings for disposal.


REGULATORY REPORTING:  Do not flush to drain. If required proper authorities should be notified.


SECTION 7.  STORAGE AND HANDLING PRECAUTIONS---------------------------------------


STORAGE:                                  Store in tightly closed, properly vented containers away from heat, sparks, open flame and strong oxidizing agents. Storage under nitrogen is recommended to minimize possible formation of highly reactive peroxides.

HANDLING:                               Keep away from heat, sparks, open flames and strong oxidizing agents.

                                                      Avoid breathing vapors.

                                                      Use with adequate ventilation.

                                                      Avoid contact with skin, eyes, and clothing.  Have available                                        safety shower and eyewash.

                                                      Wear recommended personal protective equipment.

                                                      Wash with soap and water after handling.






PROTECTION:                           No occupational exposure limits have been developed for this material. Where exposure through inhalation may occur from use, approved respiratory protection equipment is recommended.

VENTILATION:                          General mechanical ventilation or local exhaust is sufficient under normal conditions.

SKIN PROTECTION:                 Impervious butyl gloves are recommended.

EYE PROTECTION:                   Chemical splash goggles and/or face shields are recommended.
