- Ready-to-Use Product Features
- Performance and Features
- This series of potting glue is suitable for various potting modes.
- Low stress, more effective protection of electrical components.
- 100% solid, no exudate after curing
- Excellent high and low temperature resistance, excellent weather resistance
- Radiation and superior dielectric properties.
- Stable chemical and mechanical properties
This series of products are also widely used for bonding heat-generating electronic devices and heat sink or metal case. TPC-219 has excellent properties before curing Good fluidity and leveling. After curing, it will not be caused by cold or heat alternate use to escape from the protective case. Its potting surface light slip and no volatiles are generated. The curing system of this product has excellent. Good anti-toxicity, no need to solder and paint under normal circumstances and so on for special treatment.

Technical Details & Test Data
- Crosslinking/Curing Time
PAKCOOL® TPC-219 silica gel at room temperature for 8 cures naturally within 24 hours. Its cross-linking time will vary with temperature shortening as the temperature increases (see table below)
25°C 24 Hours 70°C 40 Minutes 100°C 25 Minutes 125°C 20 Minutes
Safety & Health
- Precautions
- The thermally conductive potting compound may not cure or be incomplete in contact with some substances curing, these substances include: sulfur, phosphorus, nitrogen hydrates, water, organic salts, etc. If the operator smokes before the operation, because there will be sulfur residues on your hands when you smoke, please wash your hands with soap before operate silicone
- Please seal and store, the mixed rubber should be used up at one time, avoid waste.
- Keep away from children
Storage & Handling
- Shelf Life
- 12 Months (at less than 20°C)
