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 completely react, 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.

Leak or leak program


Eliminate all ignition sources and ventilation areas. Wear protective equipment, stop the overflow at the source and dam area, and pump the liquid into the rescue tank if possible. Or, use verstone or sand to absorb the residue. Use a non-sparking tool to shovel it into a labeled waste container. Flush the area with water, but prevent it from entering the water course. Dispose of waste in accordance with local, state and federal regulations. According to EPA and dangerous goods regulations, it may be necessary to report leaks/leaks.

 

Fire fighting procedures


Wear protective clothing and equipment, including self-contained breathing apparatus. Usually, foam or carbon dioxide is used to extinguish the fire. (Please refer to MSDS). Use water spray to cool fire-exposed containers.

 

Storage and handling procedures


DG level 3 (flammable liquid). Store it in a cool and properly labeled container. The container should be placed in a cool place with a floor and ventilation in the breathing area to remove vapors that accumulate at these levels. Make sure to eliminate all sources of ignition. Keep away from strong oxidants. Do not transfer to unmarked containers. Do not transfer to unapproved plastic containers. Ground when pouring into the container to prevent electrostatic discharge.
