This innovative new PUR hot melt of the Jowatherm-Reaktant® product family has already been tested successfully according to the latest RAL-GZ 716 standard which became valid in May 2013. Especially the excellent peel strength value above the required limit by the RAL-GZ of 3 N/mm is one outstanding feature.
Additionally the very fast crosslinking allows down-line processing of the laminated profiles within one day. The greatly enlarged spectrum of adhesion and the exceptional hydrolysis stability are further advantages and are confirmed by the present SKZ certificates.
At the SKZ, this new PUR hot melt adhesive was also tested in combination with the new VOC-reduced Jowat Primer for a variety of foils, with superior positive results. This new primer was developed without NEP, a product subject to hazard labelling restrictions and contained in most standard low-VOC primers on the market for PVC window profiles. This primer is the first in a series of products formulated by Jowat which is completely free of NEP – reflecting our awareness regarding health protection and sustainability.
