Structure

3M 4646 double-sided adhesive tape adopts a multi-layer composite structure, with a high-tensile strength reinforced carrier as the core, double coated with high-performance modified acrylic adhesive with excellent initial adhesion and permanent bonding performance. The adhesive layer is designed with optimized thickness and viscosity, which not only ensures strong bonding force but also facilitates precise die cutting processing, realizing the perfect combination of structural stability and formability. The back coating of the tape is matched with die cutting process requirements, which can avoid sticking to the mold during processing and improve the yield of die cut finished products.
