- Requires the addition of a platinum catalyst to develop PSA properties
- Coating bath should be used within six hours of catalyst addition
- Adhesives can be cured in vented, continuous coating ovens at low temperatures (80°C, 176°F)
- On flexible substrates, typical cure speeds range from 1 minute at 125°C (257°F) to 2 minutes at 100°C (212°F)
- Changing the catalyst level has little impact on the tack, adhesion or cohesive strength of the cured adhesive
