Processing
- Surface preparation
- All surfaces must be clean and free of contaminants that will inhibit the cure of SEMICOSIL® 986/1K. 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® 986/1K can be dispensed easily with all dispensing equipments. Since silicones dissolve notable amounts of air, an in-line degassing is recommended.

- Curing
- SEMICOSIL® 986/1K works best when cured at 115 °C or more depending on the size and heat sink properties of the components.
- Temperature Curing time, thickness 10 mm
- 100°C - 6 h
- 130°C - 30 min
- 150 °C - 10 min
- Adhesion
- SEMICOSIL® 986/1K shows good primerless adhesion to many substrates. We recommend running preliminary tests to optimize conditions for the particular application.
