Product Overview
This clear grade potting silicone includes addition curing and condensation curing formulas, dedicated to transparent encapsulation, sealing, filling and buffer protection of electronic parts. It delivers excellent adhesion and thermal stability for PCB, PC, PMMA, CPU and various metal substrates including aluminum, copper and stainless steel. After curing, it forms fully transparent, flawless protective layers that absorb thermal cycling stress and shield chips and gold bonding wires. It also features dustproof, anti-corrosion, ozone-resistant and shockproof performance for long-term stable protection.
Technical Specifications
This high-transparent Silicone Encapsulant boasts ultra-high light transmittance with non-yellowing performance. It supports continuous stable operation at -60℃ to 220℃, with ultra-low volatile content and high structural strength. It maintains stable clarity and physical performance under long-term high-temperature aging and chemical erosion. Viscosity, hardness and operating time can be fully customized to match diverse transparent packaging requirements.
Product Features & Advantages
Different from ordinary translucent or easy-yellowing potting glue, this clear grade product owns unique competitive advantages:
1. Ultra-high transparency: Crystal clear after curing, no impurities, realizing visible inspection of internal electronic structures.
2. Long-term anti-yellowing: Prevents color fading and yellowing under high temperature and long-term operation, retaining perfect light transmittance.
3. Full protective performance: Integrates waterproof, moisture-proof, dustproof and shockproof functions with outstanding chemical and ozone resistance.
4. Superior bonding performance: Firmly adheres to multiple substrates with low volatility, no pollution to precision circuits.
Application Scenarios
Perfect for LED lighting products, display screens, optical electronic modules and visible consumer electronics. Its high transparency ensures stable light transmission and beautiful product appearance, while reliable protection reduces component failure rates. It effectively lowers manufacturers’ defective product losses and after-sales costs, improving product grade and market competitiveness.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A evenly and shake component B thoroughly to ensure uniform raw material status.
2. Proportional mixing: Strictly follow standard AB weight ratio to guarantee transparent and flawless curing effect.
3. Vacuum defoaming: Place mixed glue in a 0.01MPa vacuum container for 3-minute defoaming to eliminate tiny bubbles.
4. Curing treatment: Adopt room temperature or heating curing; full curing takes 24 hours, affected by ambient temperature and humidity.
Certifications & Compliance
This product complies with ISO9001, CE and ROHS international standards, meeting global transparent electronic packaging and cross-border export specifications.
Customization Options
Custom services are available. Hardness, viscosity, operating time and transparency grade can be adjusted for personalized packaging solutions.
Production & Quality Control
We adopt dust-free standardized production and strict anti-yellowing testing. Pre-production inspection and pre-shipment full testing ensure stable transparency and consistent batch quality.
FAQ
Q1: Will this clear potting silicone turn yellow after long-term use? A: No. It adopts anti-aging formula with excellent anti-yellowing performance, maintaining high transparency for long-term service.
Q2: Is stratified colloidal usable after storage? A: Yes. Slight stratification is normal, and even stirring will not affect its transparency and protective performance.
Q3: How to store mixed clear Potting Compound ? A: Seal and store raw materials in dry environments. Mixed AB silicone should be used up at one time to avoid bubble generation and performance degradation.
