Are diisocyanates safe?
Like many substances, diisocyanates’ use is safe when they are handled according to relevant risk management and safety measures. It is also important to know that no diisocyanates can be found in finished articles. Diisocyanates are only used as reactive chemicals; they react with the polyol to form the PU product and are consumed during curing.
What is sensitization?
Sensitization means that after exposure, a person could become allergic to the substance. This also happens to many people in contact with pollen or mould. If sensitized, each time the person is in contact again with the substance (even at very low concentrations) the person could have a high allergic reaction with respiratory impacts (e.g. asthma). The majority of individuals with related asthma show improvement or total recovery after exposure stops.
What does a distributor or reseller need to do?
He should pass on the information from the product supplier on to his customers. The training requirement prior to professional use, will already be printed on the packaging. As a distributor does not use the product himself, no training of shop personnel is required.
How does the restriction influence consumer use?
This new regulation only applies to professionals and industry. A separate restriction for consumer use came into force several years ago, introducing the requirement to include gloves with the packaging of PU consumer products.
Should PU products in retail channels be labelled accordingly?
As it is possible for professional users to purchase PU products in retail channels, NPT Srl recommends to include the new labelling sentences on retail PU products as well. This will be prepared by NPT Srl for all PU products.
Will PU adhesives, sealants and foams remain available?
The restriction aims to avoid unsafe handling of diisocyanates, not to restrict product availability. Due to their unique properties in many applications PU adhesives, sealants and foams will remain widely available.
What timing is required?
The new regulation means that by 24 August 2023 all professional users of PU products should be trained and certified. The training requirements should be mentioned on the packaging placed on the market as of 24 February 2022. PU products that have been placed on the market before 24 February 2022, are not affected by this regulation with regard to this labelling requirement.
