First aid measures
General advice: seek medical attention. If breathing stops or is difficult, give assistance in
Breathing. Supplemental oxygen may be needed. If the heart stops beating, the
Trained personnel should begin CPR immediately.
SKIN CONTACT: Remove contaminated clothing and any foreign chemicals immediately, if
this can be done without delay.

Ingestion: Do not give an unconscious person anything by mouth. Prevent inhalation
Vomiting. Turn victim’s head to one side.
INHALATION: Transfer to fresh air.

personal protective measures:
Use self-contained breathing apparatus and chemical protective clothing.
Wear appropriate protective clothing, gloves and eye/face protection. Remove all
source of ignition. Evacuate personnel to a safe area.
ENVIRONMENTAL PRECAUTIONS: Shut down or remove all sources of ignition. Dike to prevent spread.
CLEANUP METHODS: Approach suspected spill area with caution. Exposure Air Product Emergencies
Consult response center. Absorb with inert absorbent material such as:
Dry sand. Vermiculite. Activated charcoal. Place in appropriate chemical waste
containers.
OTHER RECOMMENDATIONS: Evacuate area and do not approach spilled product. If possible, stop flow of
product.

Packaging:
200KG/drum Storage: it is recommended to store in dry and cool area with proper ventilation. Please fasten the packaging cover as soon as possible after the original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the product performance. Store in a cool and dry place, keep the container sealed and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash before use. Maintain good hygiene practices. Air Chemicals recommends that all polyurethane catalysts be stored in a dry, cool and properly ventilated area, and that all storage containers be well sealed to avoid contact with water or other affected substances which may alter the performance of the product in use. Storage temperature is 10°C to 30°C.

Polyurethane foaming catalyst is a substance that can accelerate the foaming of polyurethane resin. They are used in a variety of applications including the production of flexible, rigid and specialty foams.

There are many types of polyurethane blowing catalysts, each with its own advantages and disadvantages. Some of the most common types of polyurethane blowing catalysts include:

Amines: Amines are the most common polyurethane blowing catalysts. They effectively catalyze the reaction between isocyanate and water to produce carbon dioxide gas, which creates foam. However, amines also lead to the formation of undesired by-products, such as amines and amides.
Organotin compounds: Organotin compounds can also effectively catalyze the reaction of isocyanate and water to generate carbon dioxide gas. However, they are more expensive and difficult to handle than amines.
Metal salts: Metal salts, such as zinc chloride, can also be used as polyurethane foaming catalysts. They are less expensive than amines and organotin compounds, but not as effective at catalyzing the reaction of isocyanates and water to form carbon dioxide.
The choice of polyurethane blowing catalyst depends on a variety of factors, including the type of polyurethane resin used, the properties desired in the final product, and the cost of the catalyst.

Polyurethane blowing catalysts are an important part of the polyurethane manufacturing process. They help ensure that polyurethane resins are properly foamed and that the final product has the desired properties.
