Shenzhen Potting Compound Factory 10:1 RTV Silicone for Circuit Board Sealing Power Supply

HANAST HN-8808 A/B RTV Silicone Potting Compound for Circuit Board Sealing and Power Supply

HN-8808 A/B is a two-part condensation-cure RTV-2 silicone potting compound supplied in a 10:1 ratio and designed for circuit board sealing and power supply waterproof protection. Manufactured in our China (Guangdong, Shenzhen) potting compound factory, it cures at room temperature into a transparent elastomer that bonds without a primer, insulates, damps vibration and forms a durable moisture barrier for outdoor and industrial electronics.

Key Features

• Self-priming adhesion to aluminium, iron, acrylic and PC plastic, eliminating the primer step
• 10:1 mix ratio by weight with room temperature (RTV) curing, no oven or UV lamp required
• High dielectric strength of 14 kV/mm or more for high-voltage power supply isolation
• Wide operating temperature range from -50°C to 200°C
• Superior moisture barrier that protects boards from humidity, condensation and salt spray
• Non-toxic, odorless and non-corrosive neutral cure releasing no by-products
• Small chemical shrinkage with no exotherm and no post-cure PCB warping
• Transparent cured elastomer for visual inspection of the sealed assembly
• RoHS and REACH compliant, supplied as a general chemical with SDS available
• 6 months shelf life with stable storage and easy shipping

Typical Applications

• Circuit board sealing: industrial control PCBs, IoT gateway boards, alarm controllers and HVAC modules
• LED power supply and driver: outdoor street light drivers, floodlight modules and LED display power supplies
• Waterproof power supplies: outdoor switching power supplies, rain-proof enclosures and marine adapters
• Automotive electronic modules: under-hood controllers, headlamp drivers and battery management PCBs
• Aluminium substrate and metal-housed power module potting requiring strong adhesion
• General electronic encapsulation requiring transparent, waterproof and insulating protection
