HONG YE SILICONE’s Hydrophobic Water Repellent Electronic Potting Compound is a professional water beading encapsulation material designed for humid, wet and underwater electronic working environments. It supports efficient moisture exclusion module potting and provides stable underwater operation protection. This modified two-part silicone features super hydrophobic surface performance, effectively repelling water and blocking moisture penetration. It maintains stable encapsulation and insulation performance in long-term damp conditions, greatly improving the waterproof reliability of outdoor and underwater electronic modules.
Product Overview
Available in addition and condensation curing formulas, this waterproof Electronic Potting Compound is dedicated to encapsulation, sealing and pressure-resistant filling of damp-prone electronic components. It delivers excellent adhesion and thermal stability for PCB, PC, PMMA, CPU, aluminum, copper and stainless steel substrates. The cured silicone works stably from -60℃ to 220℃, absorbs internal thermal cycling stress, and protects chips and bonding wires while achieving long-term moisture-proof and water-repellent protection. Technical Specifications
Formulated with high hydrophobic nano fillers, this water beading encapsulation material has low volatile content, outstanding ozone resistance and chemical erosion resistance. It retains excellent heat dissipation performance comparable to our classic Thermally Conductive Potting Compound. We customize viscosity, cured hardness and hydrophobic strength to meet diverse moisture exclusion module potting and underwater operation protection demands.
Product Features & Advantages
This hydrophobic silicone outperforms ordinary waterproof potting products with upgraded surface water repellency:
1. Super Hydrophobic Performance: Adopt professional water beading encapsulation technology to make water droplet slide off the surface without infiltration.
2. Efficient Moisture Isolation: Realize precise moisture exclusion module potting to block humid air and capillary moisture penetration permanently.
3. Underwater Adaptability: Provide reliable underwater operation protection for electronic modules working in intermittent or long-term underwater environments.
4. Comprehensive Protection: Integrate insulation, dustproof, shockproof and wide temperature resistance to ensure stable device operation in wet environments.
Application Scenarios
As a high-grade waterproof Electronic Encapsulation Adhesive, this product is widely used for outdoor monitoring electronics, underwater sensing modules, landscape lighting and humid industrial control equipment. It effectively reduces circuit short-circuit and aging failure rates, serving as an upgraded alternative to ordinary waterproof Silicone Encapsulant. Step-by-Step Usage Process
1. Pre-Stirring: Fully stir Part A to evenly disperse hydrophobic functional fillers and shake Part B thoroughly for uniform mixing.
2. Accurate Proportioning: Mix A and B components strictly by standard weight ratio to retain stable water repellent performance.
3. Vacuum Defoaming: Place blended silicone in a 0.01MPa vacuum container for 3 minutes to remove bubbles for seamless waterproof encapsulation.
4. Curing Operation: Support room temperature or heating curing; full curing takes 24 hours, with stable low-humidity conditions ensuring optimal hydrophobic effect.
Certifications and Compliance
All HONG YE SILICONE products pass ISO9001, CE and RoHS international certifications. This hydrophobic potting compound complies with global outdoor and underwater electronic waterproof safety standards.
Customization Options
We offer personalized customization. Clients can adjust viscosity, hardness and hydrophobic grade to develop exclusive moisture exclusion module potting solutions.
Production Process
We adopt dust-free standardized production and strict waterproof aging testing. Every batch is verified for water repellency and moisture resistance to ensure qualified water beading encapsulation and reliable underwater operation protection.
FAQ
Q1: What is the difference between this and ordinary waterproof potting silicone?
A: It forms a super hydrophobic surface for water beading encapsulation, realizes professional moisture exclusion
module potting, and provides long-term underwater operation protection that ordinary products cannot match.
Q2: Will colloid stratification affect waterproof performance?
A: Stratification is a normal storage feature. Stir evenly before use, and its hydrophobic and moisture-proof
performance remains unchanged.
Q3: Can it be used for long-term submerged electronic devices?
A: Yes. Its excellent water repellency and sealing performance effectively isolate water penetration, perfectly
suitable for long-term underwater electronic module protection.
