Product Feature:
1.1. At room temperature, the A/B glue can be operated for a long time after mixing (operable time: the period before the glue gels and thickens); under heating conditions, it can be quickly cured, which is conducive to use on automatic production lines. 1.2. It has high temperature resistance: after the glue is completely cured, it can maintain the elasticity and insulation properties of silicone rubber in the temperature range of (-60 ~ 250) ℃
Product Application:
Used for potting and thermal insulation of battery packs, potting and protection of high-power electronic components in module power supplies and circuit boards. Such as automotive HID lamp module power supplies, automotive ignition system module power supplies, solar panels, transformers, sensors, etc.
