Applications & Uses

Applications
  • General-purpose adhesive for the electronics industry
  • FIPG and CIPG applications
  • Power semiconductor insulation coating

Processing

Surface Preparation

All surfaces must be clean and free of contaminants that will inhibit the cure of SEMICOSIL® 988 TIC. 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 high thixotropy (shear thinning effect) SEMICOSIL® 988 TIC can be dispensed easily with all dispensing equipments.

Curing

SEMICOSIL® 988 TIC works best when cured at 125 °C or more, depending on the size and heat sink properties of the components. SEMICOSIL® 988 TIC shows good primerless adhesion to many substrates. We recommend running preliminary tests to optimize conditions for the particular application.
