Product Overview
This thermal shock resistant Potting Compound includes addition curing and condensation curing formulas, dedicated to encapsulation, sealing, filling and pressure protection of precision electronic components. It delivers exceptional adhesion and thermal stability for PCB, PC, PMMA, CPU, aluminum, copper and stainless steel substrates. It stably operates in a wide temperature range of -60℃ to 220℃, effectively buffering strong thermal shock stress generated by rapid temperature cycling and protecting internal chips and gold bonding wires. It also integrates waterproof, insulation, dustproof, anti-corrosion and ozone-resistant multi-functional protection.
Technical Specifications
Featuring ultra-strong thermal shock resistance, this Silicone Encapsulant maintains intact structure and stable performance after repeated extreme temperature cycles. It has ultra-low volatile content, high tensile strength and excellent chemical erosion resistance. Its physical and insulating properties will not deteriorate under drastic temperature changes. Core parameters including viscosity, hardness and operating time support full customization to meet diverse harsh working condition standards. Product Features & Advantages
Superior to ordinary potting silicone that easily cracks under temperature alternation, this product has exclusive core advantages:
1. Outstanding thermal shock resistance: Resists rapid cold and hot cycle impact, avoiding cracking, peeling and failure caused by thermal stress.
2. Full environmental protection performance: Integrates waterproof, moisture-proof, dustproof and shockproof functions with great ozone and chemical corrosion resistance.
3. Ultra-wide temperature adaptability: Works stably in extreme low and high temperature environments without performance attenuation.
4. Reliable bonding performance: Firmly adheres to various metal and non-metal substrates with low volatility and high structural stability.
Application Scenarios
Widely used in automotive electronics, outdoor communication equipment, aerospace modules and industrial control devices with frequent temperature changes. It effectively avoids component damage and circuit failure caused by thermal shock, reduces product defective rate and after-sales maintenance costs, and greatly improves the durability and market competitiveness of electronic products.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A to evenly distribute settled fillers and shake component B thoroughly before use.
2. Proportional mixing: Strictly follow standard AB component weight ratio to ensure stable thermal shock 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.

FAQ
Q1: What is the core advantage of this thermal shock resistant potting compound?
A: It can withstand frequent extreme temperature cycles, absorb thermal stress, and prevent encapsulation layer cracking and electronic component failure.
Q2: Is stratified silicone usable after long-term storage?
A: Yes. Slight stratification is normal, and even stirring will not affect its thermal shock resistance and protective performance.
Q3: How to store mixed potting glue?
A: Store raw materials in sealed and dry environments. Mixed AB silicone should be used up at one time to avoid performance degradation.
