HY-9030 Black Thermal Conductive Potting Silicone for Industrial PCB Protection
HY-9030、HY-E9020
The HY-9030 is a black, two-part addition-cure electronic potting silicone engineered for industrial PCB protection in demanding environments. In industrial automation settings, electronic control boards face an assault of challenges: constant vibration from machinery, exposure to coolant mist and metal dust, temperature cycling from equipment operation, and chemical contamination from the manufacturing environment. The HY-9030 provides comprehensive protection against all these threats in a single encapsulation solution.
Quantity
The black formulation offers an additional advantage beyond aesthetics: it provides complete UV blocking and light shielding for photosensitive components. This makes it ideal for applications where light exposure could affect circuit performance or where the visual concealment of circuit details is desired for competitive protection.
Industrial electronics failures are costly, causing unplanned downtime, production losses, and expensive emergency repairs. The HY-9030 addresses the root causes of failure by creating a sealed, vibration-damped, thermally conductive environment that extends PCB life by factors of 3-5x compared to unprotected assemblies. Field data from CNC machine tool applications shows potted control boards lasting 8+ years without failure, compared to 1-2 years for unprotected boards.
Manufactured by Shenzhen Hong Ye Jie Technology Co., Ltd., a company with over 26 years of silicone expertise, the HY-9030 benefits from decades of formulation optimization and application experience. Production follows ISO 9001 quality management with full traceability from raw materials to finished product.
Key Features
•Medium Viscosity Gap-Filling — At 1500+/-300 mPa.s, the HY-9030 provides the ideal balance between flowability and gap-filling capability. It flows readily to cover components while maintaining enough body to fill gaps and voids without excessive sagging on vertical surfaces.
•High Thermal Conductivity — With >=0.4 W/mK thermal conductivity, the HY-9030 efficiently transfers heat from power components like MOSFETs, diodes, and voltage regulators to the enclosure, preventing localized hot spots that cause premature failure.
•Black UV Protection — The black color completely blocks UV radiation and visible light, protecting photosensitive components and preventing UV degradation of the potting material itself in applications with light exposure.
•UL94 V-0 Flame Retardancy — Achieves the highest UL flame retardancy rating, self-extinguishing within 10 seconds of flame removal. Essential for industrial safety compliance and insurance requirements.
•Elastic Vibration Damping — The cured elastomer absorbs and dissipates vibration energy, protecting solder joints from fatigue cracking and connector contacts from fretting corrosion. Critical for machinery-mounted electronics.
•Chemical Resistance — Resistant to common industrial chemicals including cutting fluids, hydraulic oils, coolants, solvents, and alkaline cleaners. Protects circuits in machining centers, stamping presses, and other harsh manufacturing environments.
•Wide Temperature Range — Performs reliably from -60C to 200C, accommodating the extreme temperature variations found in industrial facilities from cold startups to hot running conditions.
•Environmental Compliance — RoHS and REACH compliant with no restricted substances. Safe for use in all global markets and compatible with lead-free manufacturing processes.
•Strong Adhesion — Bonds well to FR-4, aluminum, steel, and common engineering plastics without primer, creating a complete seal that prevents moisture ingress at material interfaces.
Application Scenarios

- CNC Machine Controllers — Protection for motion control electronics in machining centers, exposed to vibration, coolant mist, and metal particles.
- Welding Machine Electronics — Heat and spatter resistant protection for welding power supply circuits and control boards in fabrication shops.
- Conveyor System Controllers — Reliable protection for variable speed drive electronics in material handling systems operating continuously in industrial environments.
Operating Guide
Step 1: Prepare the PCB assembly by cleaning with isopropyl alcohol to remove flux residue, dust, and contaminants. Allow to dry completely before potting.
Step 2: Verify material temperature is 20-25C. If stored in cool conditions, allow to warm to room temperature before use to ensure proper viscosity and mixability.
Step 3: Dispense Part A and Part B in exact 1:1 weight ratio using calibrated equipment. For manual mixing, use a scale with 1g accuracy minimum.
Step 4: Mix thoroughly for at least 3 minutes, scraping the sides and bottom of the mixing container to ensure complete blending. The mixture should be uniformly black with no streaks.
Step 5: Dispense the compound into the PCB enclosure, directing flow to fill from one end and allowing the material to advance across the board to push air ahead of it.
Step 6: Vacuum degas at -0.1 MPa for 5-10 minutes immediately after dispensing. This removes trapped air bubbles that could compromise protection.
Step 7: Cure at room temperature for 3-6 hours, or accelerate with heat at 60-80C for 1-2 hours. Do not exceed 120C during cure.
Step 8: Inspect the cured assembly for complete fill, absence of voids, and proper adhesion to all surfaces. Perform electrical functional testing before final assembly.
