Responsible Care Summary

BUTYL ACRYLATE (BA)

Chemical Identity:

Butyl Acrylate (BA) is an acrylic monomer product, and is composed primarily of butyl acrylate, along with small amounts of the stabilizer methoxyphenol.

Product Uses and Applications:

Rohm and Haas’s BA is used as an additive in a wide range of finishes, coatings, adhesives, inks, lubricants, plastics and saturating substances.

Physical/Chemical Properties and Safe Handling:

• BA is a clear, colorless liquid with a strong, pungent, sweet odor (Odor Threshold < 1 ppb.). Both the liquid and vapor are flammable.
• Boiling point/range 148 °C (298.40 °F)
• Flash point 41 °C (105.80 °F) Tag closed cup
• Exposure can occur during the handling and transportation of BA. However, dedicated systems designed to handle BA are typically used for loading and unloading purposes, and procedures should be in place to prevent spills or leaks during transportation.
• Storage below 38°C is highly recommended to maintain stability.  Minor deviations (7C/13F) above this recommended temperature are acceptable for short periods of time (one week) for material in transit.  Keep out of direct sunlight.
• This product contains an inhibitor (methoxyphenol) to stabilize it during shipment and storage. The effectiveness of the inhibitor is dependent on the presence of dissolved oxygen, and specific precautions must be taken in order to maintain it. Do not store under an oxygen-free environment. Absence of oxygen will inactivate the inhibitor. 
• Use BA within 1 year to avoid loss of stability or risk of polymerization.  
• BA must be stored in containers made of stainless steel, glass, aluminum or carbon steel.  All containers must be tightly closed.
• Ground all metal containers during storage and handling for control of static electricity. Be sure to store in a cool place, away from direct sunlight. Limit indoor storage to approved areas equipped with automatic sprinklers.  

Health Information:

• Consumer products contain only trace levels of BA, therefore consumers are generally not exposed through finished products. Although potential for exposure does exist during the manufacture, transportation, and use of BA, enclosed systems limit the small exposure risk to worker populations and nearby communities. Skin contact may result in sensitization.  Allergic cross-reactivity to the skin with other (meth)acrylates may occur.
• Primary contact to BA is through the eyes, skin, mouth and nose, possibly leading to severe irritation and injury. Prolonged or repeated overexposure can cause the following: liver damage, kidney damage, cloudiness of the cornea, and possible toxic effects on embryos and fetuses.
• Eye contact: Rinse immediately with plenty of water for at least 15 minutes. Call a physician immediately.
• Skin contact: Remove contaminated clothing. Wash off with soap and plenty of water. If skin irritation persists, call a physician. (Wash contaminated clothing before re-use. Leather must be properly disposed, never re-use.)
• Ingestion: Drink 1 or 2 glasses of water. Never give anything by mouth to an unconscious person. Consult a physician. If vomiting occurs spontaneously, keep airway clear.
• Inhalation: Move to fresh air, and apply oxygen or artificial respiration if needed. Call a physician immediately. Odor Threshold < 1 ppb.
• Chemical resistant goggles and gloves must be worn at all times. A respiratory protection program meeting OSHA 1910.134 and ANSI Z88.2 requirements or equivalent must be followed whenever workplace conditions warrant the use of a respirator.

HMIS Hazard Ratings

Environmental Information:

• Keep spills and cleaning runoff out of municipal sewers and open bodies of water. Do not allow material to contaminate ground water systems.
• When cleaning spills, remove all sources of ignition. Contain spills immediately with inactive materials (e.g., sand, earth), and transfer liquids and solid diking material to separate suitable containers for recovery or disposal.
• Waste Classification: 40 CFR 261.20 - .24  -  Characteristic Waste   D001
• Ensure all applicable regulations are met.
