Self Leveling Sealant ShinEtsu KE-347 For Electronics Gasketing

ShinEtsu KE-347 Self-Leveling Sealant for Electronics & Gasketing

Basic Properties​

ShinEtsu KE-347 is a single-component, room-temperature-curing, neutral silicone sealant with self-leveling properties (viscosity 55 Pa·s). Density 1.04 g/cm³, post-cure Shore A hardness 30, designed for electronics sealing and form-in-place gasketing (FIPG) in -40°C to +180°C environments.

Product Description​

KE-347 cures via condensation reaction, achieving unprimed adhesion to metals, plastics, glass, and ceramics. Its neutral cure system is non-corrosive with low odor, while volume resistivity (10 TΩ·m) and dielectric strength (20 kV/mm) provide critical electrical insulation for sensitive electronics.

Characteristics​

Application Scenarios​

Consumer Electronics: Seals PCB edges in smartphones/wearables. 0.21 W/m·K thermal conductivity aids heat dissipation, compliant with IP68 standards.
EV Battery Gasketing: Form-in-place gasket for battery housings. 300% elongation absorbs vibration stress, meets UL 94 V-0 flammability rating.
Industrial Sensor Potting: Encapsulates sensing circuits. Dielectric constant 2.5 minimizes signal distortion, implemented in sensors.
Medical Device Bonding: Adheres endoscope lenses. Neutral cure prevents coating corrosion, compliant with ISO 10993 biocompatibility.
