A, use the electronic potting glue

The electronic components used to work under high temperature condition of bonding, sealing, potting and coating, can rise to moistureproof, dustproof, insulation, heat insulation, confidentiality, corrosion resistance, high temperature resistance, shock, and improve the performance and stability parameters.

Second, electronic potting glue

High temperature resistant rubber modified epoxy resin with excellent oil resistance, water resistance, acid resistance, alkali, organic solvent and high temperature resistance, and excellent dielectric properties, are widely used in high temperature sensors, electronic components, transformers, rectifiers, AC capacitor, ignition coil, the electronic module, ignition coil, atomizer and other products.

Three, electronic potting glue technology parameters

Note: the parameters in the table colloid viscosity, color, transparency, hardness, etc according to the customer's demand.

Fourth, electronic potting glue operation method

1. Mix before, first put A components mix adequately, the settlement black paint fully mixing, B component fully shake.

2. Mixed, shall comply with the components: A team B = weight ratio of 10:1.

3. When used according to the need for deaeration. Can mix A and B, the mixture evenly into the vacuum container, after the deaeration 3 minutes at 0.08 MPa, perfusion can be used.

4. Perfusion and placed in a room temperature curing, into the next procedure, basic after curing, completely curing need to 24 hours. Environment has a great influence on temperature and humidity on the curing.

Use five, electronic potting glue the note

1, the rubber should be sealed storage. Mix good rubber should be finished at a time, avoid to cause waste.

2, this product is a non-dangerous goods, but not entrance and eye. If gets into the mouth, eyes, wash immediately with water or to the hospital.

3 deposit, after a period of time, colloid is likely to stratification. Please mix after use, do not affect performance.
