Choose an adhesive by the joint you make
Sole assembly, fabric lamination, insole bonding and lasting require different adhesive categories. Identify both materials and the production step before choosing an SQ series product.
| Your application | Product options | Difference to discuss |
|---|---|---|
| Sole assembly and forming | SQ-72 / SQ-78 | Water-based PU adhesives. SQ-72 is two-component; SQ-78 is one-component. |
| Leather or synthetic leather to fabric | SQ-77 | Water-based PU adhesive for this lamination application. |
| EVA and fabric for removable insoles | SQ-518-1 | Hot-melt adhesive listed for this material pair and component. |
| Fabric and foam lamination | SQ-3968 / SQ-318HB / SQ-328HB | Separate lamination grades. Describe the application method and required hand feel. |
| PU adhesive assembly route | SQ-61 / SQ-62 / SQ-63 and related grades | Solvent-based PU category. Confirm both substrates, preparation and compatible components. |
Show both sides of the failed bond
Send a photograph of the complete joint and a close view of each separated surface. Explain whether failure occurs during assembly, after conditioning or during a test.
Include surface preparation, the adhesive currently used, drying and pressing equipment, and the required test. Confirm material-receiving instructions before sending samples.
Arrange material evaluationApplication questions
Can one adhesive cover every shoe component?
The range separates assembly, lamination, hot-melt and other footwear processes. Select around the actual material pair, equipment and required result.
Can I request bonding support without choosing a model?
Yes. Send both materials, the assembly or lamination process and your current problem. The technical team can discuss a suitable product and sample route.
