New solvent free adhesive that is less environmentally impactful

Wide Format Solutions

Using solvent free adhesives is one way to reduce the environmental impact of graphics solutions, but the use of such solvent free adhesives often comes with some performance challenges. A new innovation from Avery Dennison has addressed this challenge by boosting performance alongside reduced environmental impact.

Natascia Oprandi, product manager signage, EMENA, said that the iA Tech adhesive breaks new ground by offering a solvent free adhesive with equivalent performance to solvent based products: ‘This innovation uses state of the art Patented Advanced Acrylic Adhesive Technology (PAAAT) to eliminate solvents completely – a long standing goal, with big benefits for brand owners and graphics users. It is the latest addition to our growing sustainable graphics solutions portfolio.’

Avery Dennison 777 Cast Film and Mactac MaCal 9300 Pro are now available with this new solvent free adhesive. They both offer longer dimensional stability, along with outstanding weeding. Adhesion is equivalent to solvent based products (20 minutes and 24 hours), and the improved stability of iA Tech reduces the potential for ooze, so it allows more time between cutting and weeding.

Mark Gower, research principal, Avery Dennison, who led the project team for this new innovative adhesive said that: ‘This more reliable water dispersed adhesive now gives users much better flexibility, with more time to manage projects. There are several improvements to conventional emulsion adhesives, such as temperature resistance, transparency and whitening properties that match solvent based alternatives. Cohesion, durability and resistance to plasticiser migration are even better than products with solvent adhesive.’

Natascia Oprandi added, ‘We are especially pleased to have achieved not only a less environmentally impactful product, eliminating solvent use, but also one with so many extended benefits for applicators and brand owners. We expect many users to switch to the new technology for a range of different applications including corporate branding, vehicle markings and window graphics. In the near future, we will also be offering the new adhesive in a wider range of products.’
