Supex 4005 Electronics SIlicone Glue
Description of Supex potting epoxy
- Supex 1102 Epoxy Potting Compound is a room temperature or heat-curing epoxy resin. This two-component adhesive is designed for high-strength and secure electronic applications.
- Supex 1102 cures at room temperature without the need for heating. When parts A and B are thoroughly mixed in a 4:1 weight ratio, the product cures over time to form a protective barrier.
Post-Curing Characteristics
- Resistant to moisture, dust, and other environmental factors
- High mechanical strength
- Provides confidentiality (tamper resistance)
- Solvent-free, with no curing by-products
- Stable mechanical and electrical properties between -45°C and 120°C

Mixing & Application Process- epoxy potting compound
| Test Item | Unit | Value |
|---|---|---|
| Mixing Ratio (by weight) | — | 100:25 |
| Mixing Ratio (by volume) | — | 100:40 |
| Mixed Viscosity | mPa·s (25°C) | 700–1200 |
| Mixed Density | g/cm³ (25°C) | 1.57 |
| Working Time | min (25°C) | 40 |
| Curing Schedule | °C/hr | 80°C/1 hr or 25°C/10 hr |
Note: Working time is based on a 100g resin sample.
Instructions for Use
- Measure parts A and B, of Supex 1102 epoxy potting compound, in correct ratio, mix thoroughly in one direction to avoid excessive air bubbles.
- Stir well at the bottom and edges of the container to ensure uniformity.
- Vacuum de-gas the mixture during the working period for improved performance.
If the product volume is large, conduct potting in stages. Cure at 80°C for 60 minutes or at 25°C for 10 hours.
Precautions
- Part A may show sedimentation over time. Stir well before use and reseal tightly.
- Low ambient temperature will slow the curing process. Use heat to accelerate curing if needed.
- Do not cure directly at 80°C if potting thickness exceeds 2 cm—this may cause excessive exothermic reaction.
Heat released during curing varies by amount used; working time should be adjusted accordingly.
