Tested Silicone Potting Compound With Stable Hardness After Complete Curing
Product Overview for Silicone Potting Compound:
Process stability matters just as much as product performance. HN-8808 potting compounds deliver moderate viscosity, a 40–60 minute extended pot life and stable curing characteristics, leaving sufficient margin for production operations. Suitable for novice workers and automatic production equipment alike, they lower reject rates and lift production efficiency.
Key Performance Parameters for Silicone Potting Compound:
1. Pot Life @25°C: 40–60 mins
Sufficient long working time for assembly operations.
2. Mixed Viscosity: 2000–2600 cP
Balanced fluidity for smooth filling while avoiding overflow.
3. Mix Ratio: 10:1
Wide process tolerance, low sensitivity to proportion deviation, simple to control.
4. Curing Condition: Room-temperature cure
No heating devices required, greatly simplifying production workflow.
5.Hardness (Shore A): 30–40
Moderate elastic property, convenient for later repair and rework.
Product Highlights for Silicone Potting Compound:
1. Long working time for big batches & complex parts, less material waste
2. Great self-leveling to fill micro gaps, smooth and nice appearance
3. Simple 10:1 weight ratio, lower human error
4. Obvious surface skinning signals initial curing, easy to judge progress
5. Moderate hardness allows complete removal for equipment rework
Application Areas for Silicone Potting Compound:
1. Prototype design and performance verification testing
2. Multi-model small-batch manufacturing
3. Production plants with limited automated equipment
4. Teaching electronics projects & hobby DIY electronic assemblies
5. Precision electronic modules requiring regular disassembly and maintenance
Detailed Operating Guide (Manual Operation Focus) for Silicone Potting Compound:
1. Weighing Supplies: Prepare two clean disposable plastic or paper mixing cups and a precision weighing scale.
2. Accurate Weighing Steps: Put the cup for Part A on the scale and reset the tare value. Dispense 100 g of Component A. Keep the cup on the scale, re-tare, then add 10 g of Component B. This method eliminates weight deviations caused by cup tare.
3. Manual Stirring Operation: Take a flat stir stick and stir slowly in an infinity/figure‑eight motion. Continuously scrape the cup walls and bottom during mixing for a full 3 minutes until the mixture presents a fully consistent hue.
4. Defoaming Without Vacuum Equipment: If a vacuum chamber is unavailable, leave the blended mixture static for a few minutes to allow large air bubbles to float up. Break surface bubbles with a toothpick or gentle hot air blowing.
5. Potting Operation Tips: Pour the mixed compound from one corner of the housing and let the liquid flow to fill gaps naturally. For tall electronic components, adopt segmented pouring: fill to half the height first, wait for slight tackiness, then top up fully to avoid trapped air bubbles.
Key Precautions for Silicone Potting Compound:
1. Influence of Ambient Temperature
High temperature in summer shortens the available pot life, while low temperature in winter slows down the curing speed. Please adjust your operating schedule correspondingly.
2. Timely Use of Mixed Glue
Finish potting operations within the pot life after mixing. Never pour partially cured mixed adhesive back into the original raw material packaging.
3. Tool Cleaning Instructions
Uncured glue residue can be wiped off with alcohol. Once fully cured, only mechanical scraping can remove the adhesive.
4. Operation Protection for Long-Term Use
Wear protective goves during long-time operation and adopt ergonomic tools to ease hand fatigue.
Packaging & Storage for Silicone Potting Compound:
1. Standard Packaging Specifications
Available packages: 11kg per set and 22kg per set. Smaller weight kits better match flexible, small-batch production demands.
2. Storage Requirements
Keep the product sealed and stored in a cool and dry environment.
3. Shelf Life
6 months shelf life when kept in unopened original drums, calculated from the production date.
