About polyurethane curing agent

Polyurethane is made of two components, a polyol (also called polyhydroxy) and polyisocyanate (also called isocyanate). These are mixed in a one-to-one ratio. The polyol part is described in the part about the polyurethane resin.

For simplicity, the polyisocyanate portion of the polyurea can be referred to as a curing agent. Polyurethane can be provided as a two-pack system, where polyol is part A and polyisocyanate is part B. When these two liquids are mixed together, they will react completely, forming chemical bonds between them called crosslinks, and form a solidified solid form. Polyurethane is also available as a single-pack system, consisting of partially reacted polyurethane polymers. During the manufacturing process, these systems also react with moisture to form a solidified solid.

Polyurethane in the composite industry is used in composite laminates in the form of resin. In composite parts, resin binds the fibers together, allows loads to be transferred between the fibers, and provides a barrier to weather, water, or chemicals. Polyurethane is also used as an adhesive and can be provided in a two-pack or single-pack system. Some polyurethanes can be made into foams by adding blowing agents and using appropriate manufacturing processes.

If any of the two components of the polyurethane resin comes into contact with the eyes and skin, it may cause irritation. It can also cause irritation if any chemicals are inhaled or swallowed. The polyisocyanate part of polyurethane is more dangerous than the polyol part. This is because polyisocyanates can cause respiratory allergies. Once a person becomes sensitive, any future contact will cause an allergic reaction, even if the exposure is small.

Special Protection Information

Respiratory Protection: Adequate ventilation must be provided. If above the NOHSC exposure standard, use SA approved respiratory protective equipment. If dust is generated during cutting or machining/grinding/sanding of cured product, wear disposable dust mask (Type P1). or better as determined by you risk assessment. When using resin system (including hardener) with fibres, use combination mask with vapour and dust particle filter.

Eye Protection:Use SA approved chemical splash goggles.

Protective Clothing:Wear chemical resistant gloves such as butyl rubber or neoprene rubber gloves. Apply full dermal protection to un-covered skin. Wear full length trousers and long sleeved shirts and safety boots.

CONSULT SAFETY EQUIPMENT SUPPLIERS FOR RECOMMENDATIONS.

Effects of Exposure

Eyes:May cause irritation and redness.
Inhalation:May cause irritation of the respiratory tract. Isocyanates are known to cause sensitisation of the respiratory tract.
Skin:Prolonged and/or frequent contact can result in irritation of the skin.
Swallowing:May cause some gastrointestinal irritation.

First Aid Procedures

Eyes:Flush with water for at least 15 minutes.
Inhalation:Remove to fresh air. If breathing is difficult, seek immediate medical assistance.
Skin:Remove contaminated clothing for laundering. Wash with soap and water. Do NOT use solvents.
Swallowing: Do NOT induce vomiting. If person is conscious, they should drink large quantities of water. Seek medical advice immediately.

Spill or Leak Procedures

Eliminate all sources of ignition and ventilate area. Wearing protective equipment, stop spill at source, dam area and if possible pump liquid into salvage tank. Alternatively, absorb residue with vermiculite or sand. Scoop up using non-sparking tools into labelled waste container. Flush area with water, but prevent it from entering waterways. Dispose of waste in accordance with local, state and federal regulations. Reporting of spills/leaks may be required under EPA and Dangerous Goods regulations.

Fire Extinguishing Procedures

Wear protective clothing and equipment including self-contained breathing equipment. In general, use foam or carbon dioxide to put out fires. (Refer to MSDS). Cool fire exposed containers with water spray.

Storage and Handling Procedures

DG Class 3 (Flammable liquid). Store in properly closed, labelled containers in a cool area, fitted with floor level and breathing zone ventilation to remove vapours which collect at these levels. Ensure all sources of ignition are eliminated. Keep away from strong oxidising agents. Do not transfer to unmarked containers. Do not transfer to unapproved plastic containers. Earth containers when pouring to prevent the discharge of static electricity.
