CONVERCOAT ZR-70 the innovation in aluminum lacquering

The quality seal QUALICOAT strives to ensure more and more the quality of the products bearing it, trying to differentiate them from other materials. One of the most important developments in the latest update to the work specifications of this association (13^th edition) is the addition of a wet adhesion test.  This test consists of immersing the test pieces for two hours in distilled boiling water. Two hours after this immersion they undergo the cross-cut test and finally, the results are visually assessed.

The development of CONVERCOAT ZR-70 with technology Proquimia has been possible thanks to the progress made in nanotechnology and the recent studies on polymers. This product, approved by QUALICOAT, exceeds the wet adhesion test mentioned above as well as all other requirements set by QUALICOAT in standard working conditions.

In our experience, most of the aluminum coaters go even beyond the requirements established by QUALICOAT to achieve a still greater quality range. It is common to find facilities where the complementary impact to the cross-cut test is carried out on a regular basis, after the immersion in boiling water. Even under such extreme conditions CONVERCOAT ZR-70 is capable of delivering an extra adhesion which the lacquered aluminum industry has been looking for.
