The product is suitable for fixing electronic devices, insulation sealing, and mounting, including:
1.Sealing for insulation, waterproofing, dust proofing, damping, or airtightness; mounting; and bonding of printed circuit board, high-voltage components (such as flyback transformers), hybrid ICs, sensors and other electronic devices.
2.Sealing of coils.
3.Fixing lead wires.
・Sealing for waterproofing, dust proofing, and damping; mounting; and bonding in home electrical appliances, communication devices, or measuring instruments.
・General joining of metals, glasses or plastics.
1. Curing speed
The adhesive is moisture cure type, Thus the curing rate depends on the ambient humidity in the workplace. Curing starts at the surface in contact with air, and proceeds inwards slowly, thus taking some time to complete.
Test Piece Condition
[A 14mm deep glass dish with a 25mm inner diameter was filled with uncured SC970 and the thickness of the cured layer after being left for a certain period of time at various temperature and humidity environments was measured.]
