Viscosity is an important consideration when selecting an epoxy encapsulant. The right viscosity not only ensures good flow, but also provides good operability and curing properties. Here are some tips and tricks for choosing the right viscosity epoxy encapsulant:
Understand the needs: First of all, clarify the purpose of using epoxy encapsulant. For applications that require high strength and durability, a higher viscosity glue should be chosen; For occasions that require good filling properties, a glue with a lower viscosity should be chosen.
Working environment: The temperature and humidity of the working environment can affect the viscosity and curing speed of the glue. In a high temperature and humidity environment, a glue with high viscosity should be selected to ensure stability. In a low-temperature dry environment, a lower viscosity glue can be selected to improve flowability.
Potted objects: Objects made of different materials have different requirements for the viscosity of potting compounds. For example, when potting small precision parts, choose a low-viscosity glue to ensure even penetration. Large parts or rough surfaces may require high-viscosity glues to provide better adhesion and filling.
Operation time: Consider the time required during the operation. For occasions that require quick operation, choose a glue with moderate viscosity and easy mixing.
Brand & Quality: Choose well-known brands and quality-assured epoxy encapsulants to ensure that they have good performance and stability.
Experiments and Tests: It is very important to conduct experiments and tests before practical application. This ensures that the selected viscosity meets the actual needs and that the best potting results are obtained.
In conclusion, choosing the right epoxy potting adhesive viscosity requires a comprehensive consideration of many factors. Through an in-depth understanding of requirements, working conditions, potted objects, and operating hours, combined with experimentation and testing, we can ensure the best potting results.
