DELO-DUOPOX AD8xx – ADHESIVE GROUP CREATES HIGH MECHANICAL STRUCTURES
Introduce:
DELO-DUOPOX AD8xx adhesive group (AD = Adhesives) is a 2-component adhesive line, originating from modified epoxy resin, curing at room temperature or accelerating when heated to +80 o C, and is a resistant adhesive line. high temperature up to +150 o C and packaged in a double glue bottle, 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 from 30 to 90 minutes, enough for manual manipulation without the glue gelling.
- All glue labels meet RoHS standards according to directive 2015/863/EU.
