Product Overview for Silicone Potting Compound:
10:1 silicone potting compound is a two-component (Component A: base resin; Component B: curing agent), addition-curing silicone potting material precisely formulated at a weight ratio (or volume ratio) of 10:1. Upon curing, it forms an elastic gel or solid, specifically designed to provide insulation, thermal conductivity, moisture resistance, waterproofing, and shock protection for electronic components.
Key Performance Parameters for Silicone Potting Compound:
* Mix Ratio: 10:1
* Curing Profile: Cures at room temperature, no extra equipment needed – Simplifies the process.
* Hardness (Shore A): 25
* Viscosity (before curing) (mPa.S):A:2000 B:50
Application Areas for Silicone Potting Compound:
Common Application Scenarios: Power Modules—Used for the heat dissipation and sealing of modules such as LED drivers and inverters. PCB Protection—Safeguarding sensitive circuit boards exposed to harsh environments (moisture, dust, corrosive gases). Automotive Electronics—Potting protection for controllers, sensors, and other on-board electronic components in new energy vehicles.
Key Precautions for Silicone Potting Compound:
Precise Measurement: Components A and B must be mixed in a strict ratio of 10:1; excessive deviation from this ratio may result in incomplete curing or compromised performance. Mixing and Defoaming: The mixture must be thoroughly and uniformly stirred. After potting, it is highly recommended to perform vacuum degassing to eliminate bubbles, thereby preventing internal voids after curing that could negatively impact insulation and heat dissipation properties. Avoid Contaminants: Addition-cure silicone elastomers are susceptible to "poisoning" by substances containing sulfur, phosphorus, nitrogen, or tin (such as certain organotin-cured rubbers or vulcanizing agents), which can prevent curing at the contact interface.
Packaging for Silicone Potting Compound:
* Standard Packaging: 22kg/set; 11kg/set. Smaller packages suit flexible production needs.
FAQ for Silicone Potting Compound:
1. Q: The 40-minute pot life starts from when?
A: It starts from the moment Components A and B begin mixing. We recommend completing mixing, degassing, and pouring within 30 minutes, leaving a 10-minute safety margin.
2. Q: What if I accidentally get the ratio wrong, say 11:1?
A: The 10:1 ratio has some tolerance. 11:1 (excess A) may lead to incomplete cure and internal softness. 12:1 carries higher risk. Keep error within ±5%.
3. Q: How critical is a vacuum pump for performance?
A: For most consumer-grade products, sitting and manual bubble removal yields acceptable performance. For high-reliability (auto, military), vacuum degassing is essential.
4. Q: How to clean glue from skin?
A: Uncured, wipe off most with a paper towel, then wash with soapy water or alcohol. Cured silicone is insoluble and will wear off naturally; don't worry.
5. Q: Do you offer small trial kits?
A: Yes. We offer 1kg trial kits (909g A + 91g B) for process validation and performance testing. Feel free to apply.
