Munich, Germany -- Henkel launched what it says is the "first-ever" laminating adhesive containing no free isocyanates at the recent 7th ICE Europe trade show in Munich, 8-10 Nov.
The new one-component laminating adhesive Liofol Fast One LA 1640-21 has an extremely fast cure, combined with high initial bond strength, Henkel said in a 28 Nov news release.
"Our goal was to develop an adhesive that would enable just-in-time manufacturing of flexible packages," said Georg Kinzelmann, head of the R&D platform for polyurethanes at Henkel.
He added, "With this unique one-component PU laminating adhesive Liofol Fast One, curing is substantially reduced to just a few days, compared to a curing time of up to two weeks with a conventional adhesive."
The extremely fast cure of Liofol Fast One combined with a considerably higher initial tack enables packaging manufacturers to bundle printing, lamination and cutting in one single step, Henkel noted.
The company said these technical benefits create significant competitive advantages by increasing flexibility across the whole processing chain, as in addition to time saving, the reduction of warehousing costs and lower capital employed are key benefits that will be immediately apparent to converters.
