A next-generation adhesive solution that changes the "common sense" of adhesives so far. No special equipment is required. Just leave it at room temperature for 24 hours, and it will firmly bond various materials such as plastic, metal, and ceramics. Due to its elasticity, it can accommodate expansion and contraction caused by temperature changes, eliminating concerns about cracking even in cold regions. Even more revolutionary is its "easy disassembly" feature. With just a simple process, components can be separated during rework or when recycling products. In today's world, where sustainability is essential, we propose a new form of adhesion that considers the entire product lifecycle. We will prioritize providing trial products before market launch to our development partner companies.

Are you struggling with your recent efforts towards the SDGs? Do you want to contribute to the SDGs in any way? Our adhesives can help with that! For example, If you want to reduce utility costs... we can suggest adhesives that cure at room temperature as well as heat-cured ones! If you feel unwell due to solvent odors... we can propose solvent-free adhesives! To contribute as much as possible, we also offer "adhesives" made from biomass-derived materials and biomass materials tailored to your needs. Please take a look at our materials!
