Product Overview
This solvent-resistant potting silicone includes addition curing and condensation curing types, ideal for encapsulation, sealing, filling and pressure protection of industrial electronic components. It delivers outstanding adhesion and thermal stability for PCB, PC, PMMA, CPU, aluminum, copper and stainless steel substrates. Cured flexible silicone effectively absorbs thermal cycling stress to protect chips and gold bonding wires. Featuring strong solvent and chemical corrosion resistance, it also integrates waterproof, dustproof, ozone-resistant and shockproof functions for harsh industrial working environments.
Technical Specifications
This chemical-resistant Silicone Encapsulant features excellent anti-solvent and anti-erosion performance, resisting daily industrial solvents, oil and chemical liquids. It supports continuous stable operation from -60℃ to 220℃, with ultra-low volatile content and high structural strength. It maintains stable sealing and insulation performance after long-term chemical exposure. Viscosity, hardness and operating time are fully customizable to fit industrial electronic packaging standards.
Product Features & Advantages
Different from ordinary potting silicone vulnerable to solvent corrosion, this product has unique industrial-grade advantages:
1. Premium solvent resistance: Effectively resists various industrial solvents, oil and chemical liquids, preventing colloid swelling, aging and peeling.
2. All-round protective performance: Integrates waterproof, moisture-proof, dustproof and shockproof functions with excellent ozone resistance.
3. Extreme temperature stability: Relieves internal thermal stress during high and low temperature cycling to protect precision electronic structures.
4. Superior bonding strength: Firmly adheres to multiple metal and non-metal substrates with stable and durable performance.
Application Scenarios
Widely applied in industrial control electronics, automotive electronic modules, chemical plant equipment and devices exposed to oil and solvents. It prevents circuit damage and equipment failure caused by chemical erosion, extends electronic service life, reduces defective products and industrial maintenance costs, and improves overall equipment operational stability.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A to evenly disperse settled fillers and thoroughly shake component B before mixing.
2. Proportional mixing: Strictly follow standard AB component weight ratio to ensure stable solvent resistance after curing.
3. Vacuum defoaming: Place mixed uniform glue in a 0.01MPa vacuum container for 3-minute defoaming for flawless pouring.
4. Curing treatment: Supports 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 industrial electronic packaging and cross-border export specifications.
Customization Options
Customized services are available. Hardness, viscosity, operating time and chemical resistance grade can be adjusted for personalized industrial packaging solutions.

FAQ
Q1: What is the core advantage of solvent resistant potting silicone?
A: It effectively resists industrial solvents and chemical erosion, avoiding colloid failure and electronic damage in harsh chemical environments.
Q2: Can stratified glue be used normally after long storage?
A: Yes. Slight stratification is normal, and even stirring will not affect its solvent resistance and protective performance.
A: Store raw materials in sealed and dry conditions. Mixed AB silicone should be used up at one time to avoid performance deterioration.
