Jowatherm-Reaktant® MR 604.90 Product Information

2023-11-14
■Jowatherm-Reaktant® MR 604.90 is a PUR hot melt adhesive with hazard-free labelling for wrapping window profiles. The product is certified according to RAL-GZ 716 and impresses due to outstanding hydrolysis stability and high initial strength, especially on profiles with sharp contours. Jowatherm-Reaktant® MR 604.90 can be used in combination with the NEP-free, VOC-reduced primer Jowat® 406.84, with the primer Jowat® 406.78 (based on MEK) or with the primer Jowat® 406.89 (based on MC). These product combinations facilitate the bonding of over 95 % of PVC- and PMMA- (with primer) based decor foils established on the market.
■Within only 24 hours after laminating, the adhesive reaches high peel and foil tear resistances in roll peel tests according to EN 1372.
■Jowatherm-Reaktant® MR 604.90 can be processed on all wrapping machines established on the market and with the common processing parameters. Jowatherm-Reaktant® MR 604.90 is also an adhesive of great versatility with regard to feed speeds. It provides maximum flexibility in fast (up to 40 m/min) as well as in slow (from 6 m/min) processes.
■Contract laminators benefit from the possibility to remove all adhesive / the entire foil from unprimered profiles when the machine is set up or in case of frequent profile changes. This reduces material waste and promotes sustainability.
