Waterproof Silicone Potting Compound For Outdoor Charging Equipment Protection

Product Overview for silicone potting compound:

HN-8806 thermally conductive potting compound is specifically designed for the heat dissipation of power electronic devices, featuring a high thermal conductivity of 0.76 W/m·K. While maintaining exceptionally high electrical insulation strength, it significantly lowers device operating temperatures, thereby substantially enhancing system reliability and extending service life.

Key Features for silicone potting compound:

Product Applications for silicone potting compound:

1. Power Modules: Semiconductor Protection—Direct potting protection for IGBTs, MOSFETs, and diodes.
2. LED Drivers: Comprehensive Outdoor Protection—Thermal management and environmental protection for high-power outdoor LED drivers.
3. New Energy Sector: PV Inverters—Thermal control and conditioning for the power sections of photovoltaic inverters. Energy Storage Systems—High-efficiency thermal management for Power Conversion System (PCS) units.
4. Industrial Drives: Variable Frequency & Servo Systems—Insulation and thermal management for the power stages of variable frequency drives and servo drives.

Usage Instructions for silicone potting compound:

1. Substrate Pretreatment (Preparation) — Deep Cleaning: Thoroughly remove oil stains, dust, and moisture from the heating elements and heat-dissipating surfaces. Functional Objective: Eliminate interfacial thermal resistance to ensure highly efficient heat conduction.
2. Mixing & Deaeration — Uniform Mixing: Thoroughly mix Components A and B in the prescribed ratio until the mixture is completely homogeneous. Vacuum Deaeration: Vacuum degassing is mandatory to completely expel trapped air and prevent residual bubbles from forming thermal resistance barriers.
3. Potting Operation — Seamless Encapsulation: The potting compound must fully wet and completely encapsulate the heat source. Tight Adhesion: Ensure the potting compound makes intimate contact with the heat-dissipating base to achieve void-free filling.
4. Curing & Forming — Dual-Mode Curing: Supports standard room-temperature curing or accelerated curing via heating. Performance Attainment: Optimal thermal conductivity and electrical insulation properties are achieved only after the curing process is fully completed.

Packaging & Storage for silicone potting compound:

1. Standard Packaging Specifications: Two-component kit; Component A: 25 kg/drum; Component B: 25 kg/drum.
Mixing Ratio: Default 1:1 ratio packaging, designed to facilitate automated industrial metering and dispensing.
2. Storage Conditions: Environment: Must be stored indoors in a cool, dry, and well-ventilated area. Precautions: Avoid direct sunlight; keep away from open flames and heat sources; ensure containers are kept tightly sealed to prevent moisture ingress.
3. Shelf Life: Under standard storage conditions, the product has a shelf life of 6 months from the date of manufacture. Note: If the shelf life has expired, it is recommended to re-test key performance parameters; the product may be used only if it passes these quality checks.
