Processing
- Surface preparation
- All surfaces must be clean and free of contaminants that will inhibit the cure of SEMICOSIL® 989/1K. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds – especially organotin compounds.
- If a substrate’s ability to inhibit cure is unknown, a small scale test should be run to determine compatibility.
- Dispensing
- Because of the thixotropy (shear thinning effect) SEMICOSIL® 989/1K can be dispensed easily with all dispensing equipments.
- To eliminate any air introduced during dispensing or trapped under components or devices a vacuum encapsulation is recommended.
- SEMICOSIL® 989/1K shows good primerless adhesion to many substrates. We recommend running preliminary tests to optimize conditions for the particular application.
- Curing
- SEMICOSIL® 989/1K works best when cured at 115 °C or more depending on the size and heat sink properties of the components.
