Precautions before using epoxy potting glue

In the process of using epoxy potting glue, if certain key precautions are not controlled during early use, various problems may occur during or after the curing process of the product. For users to rule out product problems caused by improper operation when using epoxy sealant, HANAST will explain the key elements before using epoxy potting glue to facilitate troubleshooting before use.

1、 Prevent settlement
The settling phenomenon of potting products is common, and the same applies to epoxy potting glue. If settling occurs, the adhesive will have a lower viscosity in the upper layer and a higher viscosity in the lower layer, which will occur when used directly. After mixing, the mixing viscosity will be low or high when applied. When the viscosity is low, it will be popular but cannot block flow. When the viscosity is high, it cannot level. This is a visual phenomenon of operation, At the same time, it will also have an impact on the performance of the adhesive itself, such as hardness, density, etc. So before using the epoxy sealing adhesive, each component must be stirred evenly up and down.

2、 Proportioning
There are two types to introduce here. The first is manual mixing, especially when there is a large amount of glue to be mixed at once. It is important to mix the two components of glue evenly and intuitively, and the tools used are also particular. For example, some users who mix more than 5 kilograms of glue at once but use a stainless steel pipe the size of a chopstick for mixing will result in more than 60% solidification problems after filling the glue. Therefore, whether the mixing process can be evenly mixed depends on the mixing time The mixing method and tool selection are also very important, and it is important to choose a tool that matches the weight of the adhesive. Also, let me emphasize the weight of the ratio and the requirements for the ratio, such as whether it requires a weight ratio or a volume ratio.

The second is equipment gluing. The key control points for equipment gluing are how to ensure that the two components are mixed according to technical requirements. Here, we will explain that adjusting the pressure of the two glue supply buckets to be consistent does not mean that the operation can be carried out. When debugging, the ratio of the two glue supply buckets to be mixed at the same time is the standard mixing ratio. Therefore, this is the key point to pay attention to equipment proportioning.
