Technical Specifications
This product is a two-component electronic potting silicone, liquid before curing with adjustable viscosity according to sensor size and structure. It reaches UL94-HB flame retardant grade, cures without exotherm or shrinkage, and forms a soft, shock-resistant rubber layer after curing. Key parameters including viscosity, operable time, curing speed and hardness can be fully customized according to different sensor types (such as pressure, temperature, humidity sensors) and application scenarios, ensuring perfect适配 with sensor performance.
How to Use
1. Preparation: Fully stir Component A to mix settled fillers evenly; shake Component B thoroughly to ensure uniform material composition without stratification, avoiding affecting sensor protection effect.
2. Mixing: Blend Component A and B strictly according to the specified weight ratio, stir evenly to guarantee consistent curing performance and no interference with sensor accuracy.
3. Potting: Rely on the product’s self-defoaming and fluidity to pour the mixed silicone directly into sensor housings, ensuring it fills all tiny gaps without leaving air bubbles (vacuum defoaming is optional for ultra-precise sensors).
4. Curing: Place the potted sensors at room temperature for curing, or heat to accelerate curing (suitable for mass production); wait for full curing to achieve optimal protective performance without damaging sensor components.
