For encapsulating and potting of flame retardant for small and medium-sized and closing of the circuit board, such as capacitor coating, solid state relay potting, etc.

Directions for Use

1.Stirring A component evenly before taking use.
2.Mix A, B two components with 5:1 mass ratio, stir well and do vacuum defoaming before potting to components.
3.If necessary, continue to vacuum defoaming for components which been potted, help to increase the electrical performance of the device.
4.Curing conditions: Preliminary curing time is 8 hours at room temperature, completely cured need 24 hours; also can be heat curing, in 80°C for 2~3 hours.
5.The above tests are measured under 120g mixture of adhesive.
