skin exposure:

Rinse with running clean water.

eye contact :

The eyelids were opened and washed with running water for 15 minutes. seek medical advice.

inhalation:

Leave the scene to the fresh air. Oxygen is given during dyspnea. seek medical advice.

ingestion:

Mistake, drink the right amount of warm water, vomiting. seek medical advice.

emergency handling:

Evacuate personnel in the contaminated area to the safe area, and prohibit irrelevant personnel from entering the contaminated area. It is recommended that emergency handling personnel wear masks, goggles and work clothes. Rinse with large amounts of water and dilute it into the wastewater system. It can also be absorbed with sand, shoveled into the bucket, and transported to the waste disposal site. Such as a large number of leakage, the use of embankment shelter, and then collection, transfer, recycling or harmless disposal after waste.

Operational considerations :

non-avaible

Storage considerations :

Store in a cool, ventilated storage compartment. Stay away from the fire and heat sources. Packaging shall be sealed and shall not be in contact with the air. Should be stored separately from the oxidant. When handling, light loading and unloading to prevent damage to packaging and containers. Pay attention to the packing and handling operations for personal protection.

Product

Description

DOWANOL™ PnB Glycol Ether is a fast-evaporating, hydrophobic glycol ether with high

solvency and excellent coupling abilities. DOWANOL™ PnB Glycol Ether is extensively

used in heavy-duty cleaning formulations. It does an excellent job of solvating and coupling hydrophobic greases and oils in household as well as industrial formulations. It is partly

water soluble and miscible with most organic solvents. DOWANOL™ PnB Glycol Ether also provides excellent surface-tension lowering ability. In coatings DOWANOL™ PnB Glycol

Ether offers good coalescing ability in systems requiring fast evaporation.

Applications

• Coupling agent and solvent in household and industrial cleaners, grease and paint removers, metal cleaners, and hard surface cleaners.

• Effective coupling agent and efficient solvent for water-reducible coatings.

• Effective coalescent for lowering minimum film formation temperature (MFFT) in water- borne latex coatings.

• Active solvent for solvent-based coatings.

• Chemical intermediate for the production of epoxides, acid ester derivatives, solvents, and plasticizers.

• Effective coupling agent in waterbased agricultural formulations.
