Technical Guide: How to Prevent Silicone "Poisoning" and Ensure Perfect Curing
A common frustration in EV assembly lines is "non-curing" or "sticky surface" issues with silicone potting. At Hanast, we help our clients identify and eliminate these "poisoning" risks to ensure 100% production yield.
Key Substances to Avoid:
Addition-type silicones are highly sensitive. To ensure a perfect cure, your components and mixing equipment must be free from:
1. Heavy Metals: Specifically Tin (often found in condensed silicones), Sulfur, and Amine.
2. Uncured Resins: Avoid contact with uncured Epoxy or Polyurethane.
3. Flux Residue: Ensure PCBs are cleaned of acidic flux before potting.
The Hanast Advantage:
As a direct manufacturer, we offer more than just glue. We provide:
• Formula Customization: We can adjust viscosity and curing speed to match your specific automated dispensing lines.
• Expert Consultation: Our engineers are available to discuss vacuum degassing and application techniques.
• Free Sampling: We invite Vietnamese factories to request free samples for compatibility testing.
