Product Overview
This color stable potting silicone includes addition curing and condensation curing types, widely used for encapsulation, sealing, filling and pressure resistance of various electronic parts. It features superior adhesion and thermal stability for PCB, PC, PMMA, CPU, aluminum, copper and stainless steel substrates. After curing, the flexible silicone layer absorbs thermal cycling stress to protect internal chips and gold bonding wires. It integrates dustproof, anti-corrosion, shockproof and temperature-resistant functions, maintaining uniform color appearance for long-term outdoor and high-heat electronic applications.
Technical Specifications
This color-stable Silicone Encapsulant supports continuous stable operation at -60℃ to 220℃, with ultra-low volatile content and high structural strength. It boasts excellent ozone resistance and chemical erosion resistance, with zero obvious yellowing or color deviation after long-term aging. Core parameters including viscosity, hardness and operating time are fully customizable to fit diverse electronic packaging and appearance standards. Product Features & Advantages
Different from ordinary easy-yellowing potting silicone, this product owns unique color stability advantages:
1. Excellent color stability: Effectively prevents yellowing, fading and color deviation under high temperature and long-term working conditions, keeping uniform product appearance.
2. Full protective performance: Integrates waterproof, moisture-proof, dustproof and shockproof functions, resisting ozone and chemical corrosion.
3. Extreme temperature adaptability: Relieves internal thermal stress during temperature cycling, protecting precision chips and welding structures.
4. Superior bonding strength: Firmly adheres to multiple metal and non-metal substrates with stable performance and no aging peeling.
Application Scenarios
Ideal for LED lighting devices, display modules, consumer electronics and visible electronic assembly encapsulation. Its permanent color consistency ensures neat and uniform product appearance, avoids defective products caused by color difference, improves finished product grade and market competitiveness, and effectively reduces manufacturers’ after-sales replacement costs.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A to evenly disperse settled fillers and thoroughly shake component B.
2. Proportional mixing: Strictly follow standard AB component weight ratio to ensure stable curing and color consistency.
3. Vacuum defoaming: Place mixed uniform glue in a 0.01MPa vacuum container for 3-minute defoaming before pouring.
4. Curing treatment: Supports room temperature or heating curing. Full curing takes 24 hours, affected by ambient temperature and humidity.
Certifications & Compliance
The product complies with ISO9001, CE and ROHS international standards, meeting global electronic packaging and cross-border export quality specifications.
Customization Options
Customized services are available. Hardness, viscosity, operating time and fixed color tone can be adjusted to meet personalized encapsulation demands.
Production & Quality Control
We implement standardized production and full-process strict aging testing. Pre-production color verification and pre-shipment full inspection ensure stable color consistency and reliable batch quality.
FAQ
Q1: Will this potting silicone turn yellow after long-term use? A: No. It features premium color stability and anti-aging performance, resisting yellowing and fading under long-term high-temperature operation.
Q2: Can stratified silicone be used normally after storage? A: Yes. Slight stratification is normal, and even stirring will not affect color stability and protective performance.
Q3: How to store mixed color stable potting glue? A: Keep raw materials sealed and dry. Mixed AB silicone should be used up at one time to avoid performance deterioration.
