How to Use
1.Compatibility Test: Always test compatibility with contact materials using a small batch first.
2.Precise Measurement: Weigh Parts A/B strictly by weight ratio (1:1 or 10:1), never by volume.
3.Thorough Mixing: Stir slowly and completely for 3-5 minutes until fully uniform.
4.Vacuum Degassing: Recommended for 1-3 minutes to achieve bubble-free results.
5.Timely Potting: Complete pouring within the 20-40 minute pot life.
6.Curing Options: 3-5 hours at room temperature, or accelerate at 60°C for 20-30 minutes.
Three Critical Notes
1.Avoid Inhibitor Contamination: Prevent contact with materials containing N, P, S, Sn, Pb (e.g., certain fluxes, PVC plasticizers) to avoid cure inhibition.
2.Pre-treat High-risk Surfaces: Clean solder joints, PVC wires with solvent or apply barrier primer.
3.Use Clean, Dedicated Tools: Ensure tools are clean and not contaminated by other silicones.
Shelf Life:
Unopened packaging at room temperature (25°C): 12 months. Finished silicone molds can be stored for up to six months without loss of performance.
Storage and Transportation:
1.Mold silicone should be stored at room temperature in a dry, sealed container. Avoid contact with water to prevent deterioration.
2.This product is classified as non-hazardous for transportation.

FAQ:
1.Q: Why does the contact surface (e.g., wire sheath) remain tacky after potting?
A: This is the most common issue, usually due to inhibitors in the contact material (e.g., plasticizers in PVC, rosin residue on solder joints). Solutions: a) Replace components with silicone-compatible materials (e.g., silicone wire); b) Apply a dedicated barrier primer to incompatible parts; c) Thoroughly clean contact surfaces with solvent before potting.
2.Q: What's the difference between 1:1 and 10:1 ratios for model G830?
A: The 10:1 ratio typically cures faster, with slightly shorter pot life and higher hardness. The 1:1 ratio is easier to operate and mix uniformly. Choose based on production pace and performance needs.
3.Q: Can it be used for thermal conductive potting?
A: Yes. This product is an excellent base for thermal potting compounds. Choose a suitable viscosity grade and add our thermal fillers (e.g., alumina, boron nitride) at a recommended ratio. We provide technical support.
4.Q: How to accelerate curing?
A: Increasing ambient temperature is most effective. At 60°C, cure time reduces to 20-30 minutes. Ensure even heating throughout.
