One-component moisture-curing PUR hot melt adhesives have been established in the textile industry for many years.
The products are characterised by outstanding bonding properties and resistance against hydrolysis, high temperatures, and UV radiation. In general, these conventional PUR hot melt adhesives contain an excess of free monomer isocyanate (usually 4-4’- Methylene diphenyl diisocyanate – in short MDI) of approx. 2 %. Since 2002, products containing isocyanate with an MDI (CAS No. 101-68-8) content of 0.1 % or higher must be labelled with the GHS pictogram no. 8 (health hazard) and the relevant safety information (H and P statements). Depending on the concentration, isocyanates have an irritating effect on the skin, mucosa, eyes, and the respiratory system. MDI is necessary for the crosslinking reaction which determines the superior bonding characteristics.
Adhesives with an MDI content of less than 0.1 % are not subject to labelling requirements. Since the early 2000s, Jowat has already been working successfully on alternative technologies with a content below that limit.
The Jowatherm-Reaktant® MR (Monomer-Reduced) product group from Jowat supplies many PUR hot melt adhesives which are not subject to hazardous labelling requirements for a wide range of applications.
Jowatherm-Reaktant® MR 630.99 for general textile lamination is the newest addition to this product group. The PUR hot melt adhesive can be used for textile to textile lamination as well as for textile to membrane lamination on standard production lines with gravure roller or slot nozzle applicators. The requirements according to ECO-PASSPORT by OEKO-TEX® are met.
Jowatherm-Reaktant® MR 630.90 is an adhesive for laminating textiles and membranes. Good adhesion, medium initial strength.
Jowat® 930.94 is a corresponding flushing agent. For flushing applicator systems, melt units and hoses for PUR hot melts after extended downtimes or during complete standstill. Contains a reaction inhibitor to prevent the chemical reaction.
Jowat® 930.22 is a corresponding cleaner. For cleaning roller applicator systems.
