Ep3225(32a)High temperature heating curing epoxy potting material Compound

EP 3225(32a)A/B is a two-component solvent free heating and curing epoxy potting material with strong operation and excellent aging resistance at high and low temperatures.

A high-temperature heating curing epoxy potting compound is a two-part, thermosetting material designed to encapsulate, insulate, and protect electronic components, circuit boards, and mechanical assemblies. Unlike room-temperature curing epoxies, these compounds require controlled heat to initiate and complete the curing process, resulting in a rigid, chemically resistant, and thermally stable matrix.

EP 3225(32a)A/B has the following characteristics:

* Low coefficient of linear expansion

* Curing shrinkage

* High hardness and good toughness

*Excellent electrical insulation and thermal stability

* Low viscosity

* Temperature resistance Class H

*Temperature resistance range -50-200℃

* Good resistance to high and low temperature impact

Typical application

Reactor, pressure sensor, temperature sensor, industrial control module, motor stator, etc

High-temperature heating curing epoxy potting compounds are trusted in a wide range of critical applications:

Aerospace: Encapsulating avionics, satellite components, and engine sensors to withstand extreme temperatures and vibration.
Automotive: Protecting engine control units (ECUs), ignition modules, and sensor assemblies under the hood.
Electronics: Insulating power supplies, transformers, and high-temperature resistors in industrial and consumer electronics.
Industrial Manufacturing: Potting valves, pumps, and sensors in processing plants where exposure to high temperatures and chemicals is common.
High-temperature heating curing epoxy potting compounds are indispensable for protecting critical components in demanding environments. Their exceptional thermal resistance, electrical insulation, and mechanical durability make them the preferred choice for engineers and manufacturers across industries. Whether you’re designing aerospace electronics, automotive sensors, or industrial machinery, investing in a high-quality heating curing epoxy potting compound will ensure the reliability and longevity of your products.

Preparation: A\B material will have layered settlement during storage, so before each use, put the package into the oven at 60 ° C for 1 hour, and then take it out and stir evenly, at this time the viscosity will be lower than the viscosity at room temperature, and weigh in the case of temperature.
Glue: The A and B components are weighed according to the weight ratio of 100:20.
Stir evenly and set aside after vacuum debubbling.
If necessary, the potting device can continue to be vacuumed, which is conducive to increasing the electrical performance of the device.
Curing conditions: 80℃*2h+130℃/2h.

As a manufacturer, we would like to share with you what we have learned about the different types of potting compounds and their characteristics.
The potting compounds on the market vary in viscosity, requirements for cure conditions, among other factors. Compounds such as polyurethane, silicone, and epoxy are widely used in a variety of applications.
Silicone Potting Compounds are soft and flexible, silicone potting compounds and encapsulating materials possess a good level of elongation.Silicone potting compound can also withstand a wide range of temperatures. Most silicone materials are able to operate at temperatures between -40°C and 200°C.
Epoxy potting compounds generally perform as a better adhesive, high-temperature resistance, and chemical resistance and have better adhesion to a wide variety of substrates and typically do not need primers.
Polyurethane Potting Compounds generally have better flexibility, elongation, and abrasion resistance.
Acrylic Potting Compounds are UV and heat-hardening materials, with fast hardening, adequate chemical resistance, and clear appearance.
