Product Description

Product Description

Hong Ye Silicone HY-9 Series Electronic Potting Silicone is a two-component addition-cure (platinum-cure) silicone gel designed for electronic potting, sealing, encapsulation and protection. It cures at room temperature or with heat acceleration, forming a soft, transparent, self-adhesive gel that provides excellent insulation, waterproofing, shock absorption and thermal management for sensitive electronic components.

Key Features

Self-Adhesive Without Primer: Bonds directly to most substrates including PC, PP, ABS, PVC and metals, saving processing time and cost
Ultra-Low Viscosity: Flows effortlessly into tight spaces and around delicate components for void-free encapsulation
1:1 Mixing Ratio: Simple weight-based mixing reduces errors and ensures consistent curing
Flexible Curing: Room temperature cure (8h at 25°C) or rapid heat cure (20min at 80°C) to match your production schedule
Superior Insulation: Dielectric strength no less than 25 kV/mm protects sensitive electronics from voltage breakdown
Waterproof and Moisture-Proof: Forms a seamless gel barrier that prevents water ingress and corrosion
Thermal Management: Thermal conductivity no less than 0.2 W/(m.K) helps maintain safe operating temperatures
UL94 V-1 Flame Retardant: Meets international safety standards for electronic applications
Long-Term Stability: Performs reliably from -50°C to 200°C, ideal for demanding environments

Custom formulations available upon request. Hardness, viscosity, curing speed and color can all be tailored.

How to Use

Stir component A and B separately before mixing
Measure A and B at 1:1 by weight
Blend thoroughly until homogeneous
Vacuum at -0.08 MPa for 3-5 minutes to remove air bubbles
Fill into the target area or component
Cure at room temperature or accelerate with heat (80-100°C)

FAQ

Q: What substrates does the gel bond to?

A: The self-adhesive formula bonds well to PC, PP, ABS, PVC and common metals without primer. For other substrates, contact us for compatibility testing.

Q: Can I cure it at room temperature?

A: Yes. At 25°C it fully cures in approximately 8 hours. For faster production, heat cure at 80-100°C takes only 20 minutes.

Q: What is the minimum order?

A: Standard MOQ is 20kg (1 set). Sample quantities from 1kg are available for testing.

Q: Is it safe for outdoor LED displays?

A: Absolutely. The cured gel is waterproof, UV resistant and performs from -50°C to 200°C, making it ideal for outdoor LED applications.

Q: Can you customize the product?

A: Yes. We can adjust hardness, viscosity, color, curing speed and other parameters to suit your specific application.
