Product Description

Jowatherm-Reaktant® 604.35 is a PUR hot melt adhesive for window profile wrapping with RAL-GZ 716 approval. A very long open time coupled with high surface tack facilitate the wrapping of very complex profile geometries without the need for additional heating by hot air guns. The performance profile of the adhesive is rounded off by outstanding resistances to hydrolysis and thermolysis, which more than fulfill the requirements by the quality-assurance association “Gütegemeinschaft Fensterprofilsysteme e.V.”. Satisfactory peel strength data or foil tearing in roll peel tests following DIN EN 1372 can be expected after 24 hours already.*

The adhesive can be applied in combination with different Jowat® primers (preliminary testing required). Jowatherm-Reaktant® 604.35 has been developed for applications using all established wrapping machines and the common processing parameters. The formulation contains a UV tracer, which facilitates the detection of the adhesive in quality inspections on the production line. The new adhesive provides maximum flexibility and process reliability for processors at high (up to 40 m/min) as well as at low feed speeds (starting from 6 m/min).

* If processed in accordance with the parameters specified in the technical guideline “Reliable lamination of window profiles” of the Gütegemeinschaft Kunststoff-Fensterprofilsysteme e.V.
