Innovative technology from Henkel: Technomelt Supra Cool 130

 

A hotmelt for ice-cold calculators

Newly developed Technomelt Supra Cool 130 from Henkel unites the best of both worlds: a processing temperature of just 130 °C – previously the preserve of EVA-based hotmelts – fused with all the benefits of Supra technology to give exceptionally high bond strength, outstanding flowability and a much wider range of application suitability.

Henkel’s proven Supra technology is now also available at low processing temperatures. With Technomelt Supra Cool 130, Henkel has, for the first time, succeeded in reducing the application temperatures for a Supra hotmelt by an average of 40 °C, down to 130 °C.  Not only does that mean savings of up to 30 percent in energy costs, but also a reduction in adhesive consumption values of between 20 and 35 percent compared to EVA-based hotmelts.

A further benefit of this almost odorless adhesive is that, in addition to exceptional bonding strength it also features great consistency in terms of its viscosity and color-fastness. Compared to conventional hotmelts, it is thermally much more stable and flows more evenly without stringing. Moreover, its self-cleaning properties ensure immaculate processability.

Fast yet gentle
The lower processing temperature of Technomelt Supra Cool 130 means that the adhesive takes less time to melt and the processing machines can therefore get up to speed more quickly. One of the decisive advantages of Henkel’s Supra technology is thus further enhanced by the reduction in temperature: thanks to this innovative hotmelt, the amount of wear and tear to which machine components and applicators are subjected can be appreciably reduced. The maintenance input involved in removing combustion residues is also decreased, improving the overall service lifetime of the systems involved.

Using Technomelt Supra Cool 130 avoids the problem of clogged modules and blocked nozzles, again reducing machine and equipment attrition and cutting cleaning time. And this leads to yet another major plus: the outlay for spare parts is similarly reduced. Outages and set-up times can likewise be significantly decreased, with production restarting at an earlier point in the proceedings.

A real all-rounder
Technomelt Supra Cool 130 is suitable for a range of applications considerably wider than that of conventional EVA hotmelts, and it can also be readily used on a large number of different substrates and packaging materials. By introducing this new hotmelt, the packaging industry can reduce stock and stocking complexity as the need to have various types of adhesive to hand for different bonding jobs noticeably diminishes. Warm-fill contents can be packaged with the same degree of ease as frozen foods, and shipment to different climate zones likewise presents no problem whatsoever.
