UV Resistant Silicone Potting Compound 1:1 Thermally Conductive Shockproof for Outdoor PCB Electronics

UV Resistant Silicone Potting Compound 1:1 Thermally Conductive Shockproof for Outdoor PCB Electronics

This two-component addition-cure silicone potting compound is formulated for outdoor PCB and electronic component encapsulation. It cures into a durable grey rubber elastomer at 50±5 Shore A, combining UV resistance, strong adhesion to PCB substrates and shockproof vibration dampening to protect solder joints and components in demanding environments. With a 1:1 mix ratio, 0.76 W/m·K thermal conductivity and flame retardant, fire resistant performance across -50°C to +250°C, it delivers reliable heat dissipation, electrical insulation and long-term weather resistance for outdoor and industrial electronics.

Key Features

• UV Resistant & Weather Resistant — silicone backbone resists UV degradation and outdoor aging for long service life
• Shockproof & Vibration Dampening — flexible 50±5 Shore A rubber cushions components against drop, impact and vibration
• Strong Adhesion — excellent adhesion to PCB, metal and most electronic substrates, no primer required
• Thermally Conductive 0.76 W/m·K — transfers heat away from power components to extend operating life
• Flame Retardant / Fire Resistant — self-extinguishing formulation improves safety of electronic assemblies
• Wide Temperature Range -50°C to +250°C — stable from low-temperature outdoor use to high-temperature operation
• Low Shrinkage, No By-products — addition cure with no heat release or corrosive by-products, safe for sensitive circuits
• 1:1 Mix Ratio — simple, accurate dosing by weight or volume for consistent production

Applications

• Outdoor PCB and control board encapsulation
• LED lighting, power supply and driver potting
• Electronic components requiring UV, moisture and shock protection
• Industrial and automotive electronic module sealing
