Polyurethane (PU) adhesives and sealants are widely used in the construction industry. These include mounting, filling, sealing, insulation, prevention of thermal and sound bridges, and so on. The use of these products is safe as long as they are applied in accordance with established safety measures.
However, during application of PU products, diisocyanates are released. This substance, if used incorrectly, can lead to respiratory and dermal sensitisation. Therefore, European authorities have adopted a new measure on the use of diisocyanates under REACH, targeting respiratory and dermal sensitisation potentially caused by diisocyanates.
Versatile and unique product
For the record, the measure does not prohibit the use of polyurethane adhesives and sealants, but only sets training requirements for their safe use. PU adhesives and sealants will continue to be widely used because of their versatility in a variety of applications.
More information on the safe use of diisocyanates, mandatory training and required labelling can be found on the website of Safe Use of Diisocyanates and FEICA.
