Application of potting glue wetting agent
Potting glue wetting agent plays an important role in the application process of potting glue. The following is
a detailed analysis of the application of potting glue wetting agent:
I. Basic concept
Definition: Potting glue wetting agent is an additive used to improve the wettability and fluidity of potting glue
on the surface of the substrate.
Function: Wetting agent can reduce the surface tension of potting glue, making it easier to spread and penetrate on the
surface of the substrate, thereby improving the bonding force between potting glue and substrate and ensuring the potting
effect.
II. Application characteristics
Improve wettability: Wetting agent can effectively reduce the surface tension of potting glue, so that it can better wet the surface
of the substrate and reduce the generation of bubbles and defects.
Improve fluidity: By adding wetting agent, the fluidity of potting glue is enhanced, which is conducive to its filling and curing
in complex structures.
Enhance bonding force: Wetting agent helps to improve the bonding force between potting glue and substrate, ensuring the
close fit between potting layer and substrate.
Improve production efficiency: The use of wetting agent can reduce defects and rework rate in the potting process, thereby
improving production efficiency.
III. Application fields
Potting of electronic components: During the potting process of electronic components, wetting agents can ensure that the potting
glue is evenly covered on the surface of the components, improving moisture-proof, dust-proof and insulation properties.
Automotive electronic modules: Automotive electronic modules have high requirements for the wettability and fluidity of potting glue.
Wetting agents can effectively meet these requirements and ensure the stability and reliability of automotive electronic modules.
Industrial control modules: In industrial control modules, wetting agents help potting glue to better fill and cure, improving the weather
resistance and service life of the module.
IV. Precautions for use
Choose a suitable wetting agent: Choose a suitable wetting agent according to the type of potting glue and application scenario to
ensure the best wetting effect.
Control the amount of addition: The amount of wetting agent added should be controlled within a certain range. Too much or too little
may affect the performance of the potting glue.
Mix evenly: When adding the wetting agent, ensure that it is evenly mixed with the potting glue to avoid local concentrations that are
too high or too low.
Storage conditions: Wetting agents should be stored in a cool, dry, ventilated place, avoiding direct sunlight and high temperature
environment.
In summary
Potting glue wetting agents play an important role in the application process of potting glue. They can effectively improve the
wettability and fluidity of potting glue, enhance its bonding strength with the substrate, and improve production efficiency.
During use, you should choose a suitable wetting agent, control the amount of addition, mix evenly, and pay attention to storage
conditions.
