PURELAM™ A 9700 functions as the primary reactive component in the A 9700/B 9810 laminating adhesive system. Engineered for converters seeking reliable performance, this 100% solids system supports high processing speeds, efficient workflow, and consistent laminate quality across film and metallized film structures. When mixed with PURELAM™ B 9810 at a ratio of 0.9:1.0, the adhesive produces fast-developing bonds that can be slit within 6–12 hours under typical room-temperature curing conditions. The system enables smooth coating, minimal misting, and stable performance on solvent-free laminators, making it well suited for food, consumer goods, and industrial flexible packaging.
