Question 1

What kinds of encapsulation compound you provide?

Accepted Answer

We have different potting adhesive sealant based on polyurethane, epoxy and silicone type with different properties, such as hardness, operation time, thermal conductivity, color, strength,etc. Please tell us more about your application, the performance you care about most, it can help us recommend right product for you more faster.

Question 2

Which application is your industrial electronic potting sealant used for?

Accepted Answer

We can provide you with potting adhesive sealant solution for EV (electronic vehicle) and ESS (energy storgage system) , for sensor, juction box, controller, water meter, capacitor, motor, circuit board, transformers and coils, power modules, control modules, display devices, LCD monitors, drivers, filters ,etc.

Question 3

What is your electronic potting compound is mainly uesd for?

Accepted Answer

For sealing/encapsulation, insulation protection, waterproofing, moisture resistance,and shock absorption, etc. And different potting materials (such as epoxy resin, polyurethane, and silicone) have different properties, so their specific suitable appications also vary. If you have a specific component or operating environment in mind, please tell us, we can help find you a more suitable option.

Question 4

How can I get samples?

Accepted Answer

Samples request is supported, please tell us how many quatities samples do you need, ususally 200g to 500g is free sample for test, the freight charge need be paid by client.
And the freight charge depends on the gross weight of samples, if you ask for 500g samples, usually, the gross weight is about 1000g (1kg). 
Also please tell me your address to check the freight charge with our freight agent who is charging for the delivery.

Question 5

What is Conformal Coating?

Accepted Answer

Conformal coating is a thin protective layer applied to a printed circuit board (PCB). It "conforms" to the shape of the components, solder joints, and traces, forming a protective film typically 25 to 75 microns thick.

Question 6

What does Conformal Coating do?

Accepted Answer

Its core functions are:
The "Three Defenses": Moisture-proof, salt-spray-proof, and fungus-proof - this is its most fundamental role.
Electrical protection: Improves insulation resistance and prevents short circuits or leakage caused by moisture, dust, or chemicals.
Environmental durability: Protects solder joints and conductors from corrosion, and withstands thermal cycling stress.

Question 7

What are Conformal Coating applications?

Accepted Answer

It's used anywhere electronics may face moisture, chemical contamination, dust, or temperature swings:
Automotive: Chassis systems, control units-resists humidity, salt spray, oil mist, and vibration.
Consumer electronics & appliances: Washing machines, dishwashers, AC units, outdoor displays.
Industrial & medical: Industrial controllers, precision instruments.
Aerospace: Flight control systems, meeting strict moisture, corrosion, and flame-retardant requirements.

Question 8

How does Conformal Coating differ from Encapsulation Compound?(1)

Accepted Answer

Conformal coating is like "putting on clothes"; potting or encapsulation is like "burying it in concrete.
Conformal Coating:
Thickness: Very thin, around 25 to 125 microns.
Protection level: Moisture, condensation, dust. But not prolonged immersion.
Mechanical strength: Low to moderate. No shock absorption.
Repairability: High. Can be locally removed with solvents or heat.
Weight: Negligible. Adds less than 5 grams.

Question 9

How does Conformal Coating differ from Encapsulation Compound?(2)

Accepted Answer

Encapsulation or Potting:
Thickness: Thick, from millimeters to centimeters.
Protection level: Extreme. IP67 or IP68 immersion and sealing.
Mechanical strength: Excellent. Absorbs vibration and impact.
Repairability: Very low or none. Essentially unrepairable after curing.
Weight: Significant. The resin itself has weight.

Question 10

When to use Coating vs. Potting?(1)

Accepted Answer

The key trade-off is between protection strength and repairability.
Choose Conformal Coating when:
The environment involves humidity, condensation, dust, or mild corrosion, but not direct immersion or strong impact.
The product needs repair or debugging, such as component replacement or firmware flashing, or is still in prototyping.
Weight and space are critical, such as portable devices or drones.
You need to preserve thermal paths. Coating barely affects heat dissipation.

Question 11

When to use Coating vs. Potting?(2)

Accepted Answer

Choose Potting or Encapsulation when:
Facing continuous strong vibration or mechanical shock, such as motor controllers or power tools.
You need IP67 or IP68 immersion protection without an enclosure.
You need high-voltage isolation. Potting compound offers much higher dielectric strength than coating.
You need tamper-proofing or anti-reverse-engineering. Potting is nearly impossible to remove.
The product is a sealed, non-repairable module. Replace as a whole when it fails.
