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.

Question 12

What Is Silicone Liquid Optical Clear Adhesive (Silicone Liquid OCR)?

Accepted Answer

Silicone liquid optical clear adhesive (often called silicone liquid OCR or silicone LOCA) is an optically transparent adhesive used in high-end display bonding processes. Its primary function is to fill microscopic gaps between display components, improving both visual performance and structural integrity.

Question 13

What Application Is Silicone Liquid Optical Clear Adhesive (Silicone Liquid OCR) for?

Accepted Answer

It belongs to the family of liquid optical clear adhesives (LOCA/OCR). Unlike solid adhesive tapes, it is dispensed as a liquid, allowing it to fill complex structures more effectively.
Primary applications: Core use is in full lamination of touch panels and display modules -smartphones, tablets, automotive center consoles, interactive whiteboards, medical device displays, etc.
Other areas: LED encapsulation, optical lenses, light guide components, and protection/bonding of certain precision

Question 14

Key Characteristics of Silicone Liquid Optical Clear Adhesive

Accepted Answer

Excellent weather resistance, minimal yellowing: Under prolonged exposure to high temperature, high humidity, or direct sunlight, acrylate adhesives tend to yellow, degrading display quality. Silicone materials effectively resist yellowing and maintain long-term optical clarity.
Good flexibility and stability: After curing, it remains soft and flexible, with excellent vibration resistance and thermal shock resistance, maintaining stability across a wide temperature range.

Question 15

Advantages of Silicone Liquid Optical Clear Adhesive

Accepted Answer

Low cure shrinkage, low stress: Acrylate adhesives cure quickly but shrink significantly, which can deform LCD panels or cause dark spots (mura). Silicone liquid OCR has very low shrinkage, minimizing cure-induced stress and protecting sensitive components.
Superior optical performance: After curing, it is colorless and transparent, typically achieving light transmittance above 98%, reducing optical loss and improving screen brightness and contrast.
