Strong adhesive molecular gradient film double-sided tape "200A・300A"
Molecular gradient film double-sided tape 200A・300A
A revolutionary strong adhesive double-sided tape that is thin and achieves 1.5 to 2 times the performance of conventional double-sided tape!
KGK Joint Research Chemical's three-layer simultaneous coating technology (molecular gradient membrane coating technology) is a special lamination film formation technique that enhances intermolecular attraction by gradient film formation (stepwise film formation) of the same or different resin solutions from the center layer to the outer layer, creating a very strong bond. By using this technology to produce double-sided tape, we can achieve performance that was difficult with conventional double-sided tapes (such as non-woven fabric and substrate film-based double-sided tapes). Molecular gradient membrane double-sided tape and adhesive films are designed to maximize bonding with a special adhesive that enhances the total thickness of the adhesive layer (as adhesive strength depends on thickness) at the interface of the adherend material (outer adhesive layer). They also provide stress relaxation through the molecular weight gradient between layers, addressing warping of the adherend material and external impacts or load stresses. In other words, the entire thickness of the tape contributes complexly and powerfully to the characteristics of the polymer and adhesion to the adherend material interface, allowing for adhesive strength, heat resistance, and viscoelasticity that are 1.5 to 2 times greater compared to conventional double-sided tapes.
