Jowatherm-Reaktant® 604.25
Detmold, October 11, 2016 – The new PUR hot melt adhesive
Jowatherm-Reaktant® 604.25 shows superior bonding results in window
profile wrapping, and provides reliable processes and high initial strength
in combination with new primers from Jowat.
For many years, the tried and proven adhesive systems from Jowat
consisting of powerful PUR hot melts and primers have met the high
demands in window profile wrapping. Outstanding wetting properties
combined with high initial strength and a fast crosslinking
of the adhesive facilitate shorter process cycles and increase
efficiency. The growing variety of substrates and decor materials as well
as bigger variations in the surface tension of the foils required a new
adhesive. Characterised by a superior range of adhesion,
Jowatherm-Reaktant® 604.25 is the logical development of this product
group.


The significantly higher initial strength due to a considerably shorter open
time of the new PUR hot melt ensures reliable processes and a high
quality of the end product – even at higher line speeds and with rigid foils.
Therefore, Jowatherm-Reaktant® 604.25 plays a major role in maximising
the efficiency of laminating processes. In addition, the adhesive can be
molten and processed at lower temperatures, which reduces the thermal
stress on the adhesive as well as on the thermoplastic foil, and facilitates
more reliable processes of a higher quality. Jowatherm-Reaktant® 604.25
is certified according to RAL-GZ 716 for the use in combination with
conventional as well as VOC-reduced, NEP-free primers.
When processed together with the latest generation of Jowat primers, the
new high-performance adhesive provides additional benefits: The
interaction between the primer and the adhesive ensures an accelerated
crosslinking of the PUR adhesive during the laminating process of the
PVC window profile. Jowatherm-Reaktant® 604.25 is therefore the optimal
adhesive to be used in combination with these non-hazardous, modern
VOC-reduced, NEP-free primers.
