High Thermal Conductivity Silicone Potting Compound For Heat Dissipation

High Thermal Conductivity Silicone Potting Compound For Heat Dissipation

Product Overview for Silicone Potting Compound:

HN-8808 is a premium two-part silicone potting compound with an optimized low-viscosity fluid profile. It delivers exceptional self-leveling and capillary flow, effortlessly penetrating micro-gaps and completely encapsulating intricate electronic components without voids.

Product Highlights for Silicone Potting Compound:

1. This potting silicone rubber has high moisture resistance and a wide temperature range of -57°Cto 250°C.
2. Condensed liquid silicone rubber does not use polar compounds as raw materials, and doesnot release by-products during cross-linking, and can maintain better electrical propertiesunder harsh conditions.
3.  Non-toxic, odorless, non-corrosive, non-swelling.
4. It has adhesive force, has adhesion to metal aluminum, iron, acrylic, and PC plastic, and canimprove waterproof sealing performance.

Application Areas for Silicone Potting Compound:

Widely used in sealing, electrical, potting, insulation, antifouling, waterproof, shockproof coating,electronic appliances, and comprehensive household appliances.

Detailed Operating Guide for Silicone Potting Compound:

According to the dosage, pour it into the mold after mixing according to A: B=10:1.

Remove the surface bubbles and cure at room temperature (the proportion can be adjustedaccording to actual needs, the larger the proportion of component B, the faster the curing).

Key Precautions for Silicone Potting Compound:

• Strict Proportion Control: Adhere precisely to the 10:1 weight ratio; any deviation will directly prevent the compound from curing properly.
• Thorough Homogenization: Inadequate mixing will cause localized uncured spots, surface tackiness, and severe degradation of overall dielectric and shielding properties.
• No Thermal Baking: This is a condensation-cure system; applying heat will induce heavy bubbling and permanently disrupt the crosslinking reaction.
• Adequate Ventilation: Ensure robust air circulation and extraction throughout the entire potting, dispensing, and initial curing stages.

FAQ for Silicone Potting Compound:

1. Q: What is the difference between the transparent, black, and white versions?

A: The primary differences are thermal conductivity (Transparent: 0.3, B/W: 0.5 W/M·K) and optical properties. Black offers some EMI shielding, White is aesthetic/reflective, Transparent allows visual inspection.

2. Q: Can I use volume instead of weight for measuring?

A: No. Due to density differences, the volume ratio is not 10:1. Always use weight for accuracy.

3. Q: Is it suitable for outdoor use?

A: Yes, its silicone base provides excellent resistance to weathering, ozone, and UV radiation (especially black and white).

4. Q: How do I remove cured silicone for repairs?

A: The cured rubber can be cut and peeled mechanically. It is challenging but possible without damaging components if done carefully.

5. Q: What is the minimum order quantity?

A: Our standard MOQ is one 11kg kit. Contact us for smaller trial orders.
