HONG YE SILICONE’s High Flame Resistance Electronic Potting Compound is a fire-rated two-part Silicone Encapsulant formulated for high-risk electronic working environments. Featuring self extinguishing encapsulation grade and certified UL94 V0 module potting performance, this material provides reliable fire safety barrier protection to stop flame spread and isolate high-temperature sparks. It also delivers waterproof, insulation and thermal cycling resistance, an ideal protective solution for high-power electronics requiring strict fire prevention standards.
Product Overview
Available in addition curing and condensation curing formulas, this fireproof Electronic Potting Compound supports encapsulation, sealing and pressure-resistant filling for various electronic components. It features outstanding adhesion and thermal stability for PCB, PC, PMMA, CPU and mainstream substrates including aluminum, copper and stainless steel. The cured silicone runs stably from -60℃ to 220℃, absorbs internal thermal stress and protects chips and bonding wires from overheating and fire-related damage. Technical Specifications
Reinforced with halogen-free flame-retardant additives, this product reaches industry-leading UL94 V0 fire resistance rating with premium self extinguishing encapsulation grade. It cuts off oxygen supply rapidly to extinguish flames without releasing toxic fumes during combustion. It retains low volatile content, ozone resistance and excellent heat dissipation same as our mature Thermally Conductive Potting Compound. Hardness, viscosity and pot life can be customized to meet diverse fireproof encapsulation requirements. Product Features & Advantages
Compared with ordinary common-grade potting silicone, our flame retardant adhesive has prominent differentiated advantages:
1. UL94 V0 Fire Rating: Achieves professional UL94 V0 module potting, the mainstream fireproof standard for global electronic manufacturing industries.
2. Self-extinguishing Ability: Premium self extinguishing encapsulation grade prevents fire spreading and lowers short-circuit ignition risks effectively.
3. Fire Barrier Protection: Acts as a solid fire safety barrier protection layer to isolate high heat and sparks for high-power circuits.
4. Multi-functional Protection: Integrates dustproof, waterproof, anti-corrosion and insulating properties to adapt to harsh industrial scenarios.
Application Scenarios
As a fire-rated Electronic Encapsulation Adhesive, this high flame resistance silicone is widely used for power supplies, new energy battery modules, high-power LED equipment, industrial controllers and automotive electronics. Its stable fire safety barrier protection reduces fire hazards and product failure rates, helping manufacturers pass fire safety audits and upgrade product safety grade over regular Silicone Encapsulant. Step-by-Step Usage Process
1. Pre-stirring: Thoroughly stir Part A to redistribute settled fillers and shake Part B evenly before proportioning.
2. Accurate Mixing: Follow official AB weight ratio strictly to maintain intact flame retardant and physical properties after curing.
3. Vacuum Defoaming: Place blended compound in a 0.01MPa vacuum container for 3 minutes to eliminate bubbles for seamless encapsulation.
4. Curing Method: Supports room-temperature or heating curing; full curing takes 24 hours, affected by ambient temperature and humidity.
Certifications and Compliance
All HONG YE SILICONE products comply with ISO9001, CE and RoHS standards. This high flame resistance potting compound is certified with UL94 V0 rating, conforming to international fire safety regulations for electronic encapsulation.
Customization Options
We provide one-stop personalized customization. Clients can adjust flame retardant grade, cured hardness, material viscosity and operating time to match exclusive fireproof encapsulation projects.
Production Process
We adopt dust-free standardized production and multi-stage safety detection. Every batch undergoes flame retardant testing and high-temperature aging verification to deliver durable fire safety barrier protection for global electronic purchasers.
