KLEIBERIT MICRO-EMISSION (ME) ADHESIVES

Latest developments in PUR hotmelts:
Reduction of monomeric diisocyanate content for increased health and occupational safety.

What does micro-emission mean in the context of PUR hotmelt adhesives?

PUR hotmelt adhesives contain iscocyanates, which are required for the crosslinking reaction. The chemical crosslinking leads to outstanding properties of PUR hotmelts, such as outstanding heat and moisture resistance.

The iscocyanate is present both in polymer-bound form and, in small quantities, in monomeric form. When the adhesives melt during processing, vapors can be generated that contain monomeric diisocyanate. This can lead to respiratory sensitization.

According to the REACH restriction regulation (Regulation 2020/1149), chemical products containing ≥ 0.1% monomeric diisocyanate may only be used after August 24, 2023, if processors have been trained in safe handling.

KLEIBERIT offers a wide range of ME PUR hotmelt adhesives for various applications.

KLEIBERIT ME PUR hotmelt adhesives contain less than 0.1% of monomeric diisocyanate. Therefore, the PUR hotmelt adhesive does not need to be labeled as a hazardous substance.

By using KLEIBERIT ME PUR hotmelt adhesives, you and your employees are exempt from the training obligation while also ensuring improved occupational health and safety as a company.
