Better, faster, stronger lamination with Desmodur®

Copied to clipboard

Magazine covers, luxury packaging (e.g. perfume boxes), business cards, or book covers are turned into luxurious-looking prints when laminated. Lamination typically adds a matt, gloss or silky finish, while at the same time protecting the printed product to create a perception of utmost quality.

Task

Achieve better lamination performance for premium print materials

Celloglas, a UK specialist for print finishes, was looking to improve the process speed and quality of its lamination process. Celloglas turned to Scitech Adhesive Systems for support in designing a high-quality solution.
Challenge

Create a high-strength, glossy adhesive for a lasting finish

Utmost quality in this case meant finding a solution that would provide a high and reliable bond strength and a clear finish. At the same time, high-value magazines, for example, still have to maintain their high-quality appearance even after the pages have been turned many times.
Solution

Desmodur® XP2802 crosslinkers for rapid, high-strength gloss lamination

Celloglas, Scitech and Covestro cooperated closely to find the best solution to this challenge. Scitech’s new waterborne adhesive ST4520 based on the crosslinker Desmodur® XP 2802 from Covestro enables Celloglas to achieve very fast bonding and direct slitting after lamination. What’s more, as the adhesive is a one-component solution, it prevents mixing errors. Thanks to its long pot life of several weeks it even prevents adhesive waste and ensures constant adhesive quality during the application process. As Trevor Jones, the Scitech owner, says, “This adhesive is a perfect fit for gloss lamination since it offers many process and quality advantages to our customers. Its unique characteristics make it not only interesting for gloss lamination but also for flexible food packaging.” This is possible since the Covestro crosslinker can be used for food applications in line with EU 10/2011.
