Typical Applications

ADS-340 is typically used for sealing of fixed window modules, door water deflectors, and windshield reveal moldings. ADS-340 is designed to provide high bond strengths to a variety of substrates such as polyethylene, EVA, EPDM, and automotive paint systems.

General Application Instructions
  • ADS-340 can be processed with standard hot-melt pumping equipment at temperatures of 150°C to 175°C (300°F to 350°F).
  • Recommended application temperatures for use with Nordson FoamMeltTM are 163°C to 185°C (325°F to 365°F).

Clean Up

If disassembly of ADS-340 is desired, the compound may be removed by grasping the compound and rapidly (in a snapping motion) pulling it from the substrate. Any residual traces of the adhesive may be removed with an aliphatic solvent such as mineral spirits followed by a wipe with a 50/50 alcohol/water solution.
