The uses and characteristics of electronic potting glue

Electronic potting glue is a two-component polyurethane potting adhesive with low thermal conductivity, room temperature curing, long working time, and fireproof properties. Especially suitable for potting capacitors and small electronic devices. Its flexible elastic properties allow it to cover very uneven surfaces. Heat is conducted from the separation device or the entire printed circuit board to the metal housing or diffuser plate, thereby increasing the efficiency and service life of the heat-generating electronic components.

Electronic potting glueUses of:

1. LED light and power driver potting.

2. Magnetic core glue, suitable for LED type and aromatic polyester glue.

3. The relay steam hole is sealed and has good adhesion to rubber, ceramics, PCB base plates and plastics. effect.

4. Transformers, sensors, coil packaging, and current setting packaging.

5. For metal and glass, LCD air hole potting, coating and capping potting, Radiator components, thermal sensor potting, and thermal product potting have good bonding effects.

Electronic potting Characteristics of the compound:

1 , Good insulation performance and smooth surface.

2. Low shrinkage.

3. Low viscosity, easy to exhaust.

4. Good solvent resistance and water resistance.

5. Long working hours.

6. Excellent thermal shock resistance.

Electronic potting How to use glue:

When using, mix A glue and B glue according to a specific ratio. In order to ensure uniform distribution of fillers, it is recommended that component A and component B must be stirred separately before mixing. Pour the mixed compound into the device for encapsulation. Vacuuming and defoaming are generally not required. If high thermal conductivity is required, it is recommended to vacuum degas before pouring. Can be cured at room temperature or heated.
