Introduce:
DELO-PUR9xxx adhesive group (PUR = PolyUrethane) is a 2-component adhesive line, originating from modified polyurethane, curing at room temperature or accelerating when heated to +80 o C, and is a durable adhesive line. Pull apart the layers and pack them in a double glue bottle, making it easy to apply glue both manually and automatically.
Outstanding features:
- The glue is padded with inorganic mineral particles to strengthen the material's mechanical properties.
- The adhesive has a high viscosity, prevents creep when applying glue, suitable for large gaps that need to be bonded.
- Usage temperature range: from -40 °C to +150 °C depending on the type of glue and specific application.
- The adhesive is durable at high temperatures, has good solvent resistance, and is durable in the peeling test.
- The time to apply glue after mixing is only 5 to 30 minutes, enough for manual manipulation without the glue gelling and at the same time meeting the requirements for quick curing to increase production productivity.
- All glue labels meet RoHS standards according to directive 2015/863/EU.
