For novice users who use silicone electronic potting adhesive, they may find a layer of powdery sediment at the bottom of the purchased adhesive bucket. Therefore, they may wonder if there is a problem with the adhesive and if it will affect its use. So what is the situation? Below, we will provide professional analysis and interpretation of the origin of the sediment for everyone.

We can find by comparing transparent and colored silicone potting adhesives that transparent can only rely on the thermal conductivity and flame retardant properties of the raw material of silicone liquid silicone itself, with a thermal conductivity coefficient of only 0.2~0.3W/m.K, while colored silicone potting adhesives can reach around 1.0W/m.K after adding thermal conductivity powder.

From the above analysis, we can know that the sediment at the bottom of the barrel is not caused by product quality issues. Instead, it is a powder that is beneficial for improving the thermal conductivity and flame retardancy of organic silicon sealant. Before mixing AB, it only needs to be stirred first, so there is no need to worry about whether it will affect the effect after sealing.
