Remark:It may be crystallized when stored at low temperature place. After
heating to 60℃, crystal can
be eliminated; JT8068-1B contains accelerator. Prolonged storage at
high embient temperatures will result in an undesirable increase in
its viscosity and impairs the reactivity of casting resin system.

FQA:
| 1 | What’s the Pre-filled? |
| | Pre-filled is the resin or hardener has been filled with silica
sands before delivering to you. |
| 2 | Is Pre-filled resin cheaper than Pure resin? |
| | Generally it is. However, you should consider the final cost. If
you can find qualified silica sands in you local market, the pure
resin is better choice. Silica sands are very cheap, sea freight
cost is high. With same quantity of resin in a shipment, you can
get more final mixed resin with local silica sands. |
| 3 | Why JiangTe resin doesn’t offer Flexibilizer and Accelerator? |
| | We’ve added them into resin/hardener already before delivering to
you. So you can use our materials easily. |
| 4 | Should I tell you our process when purchasing? |
| | Yes, our materials have two kinds on most of items: Vacuum Casting
and Auto Pressure Gelation (APG). |
| 5 | Do you have one material which is suitable for both CT PT and
bushings insulators? |
| | No, the requirements of CT PT and bushings insulators on electrical
characters are different. We’ll help you find the suitable one. |
| 6 | We’re using Huntsman epoxy resin, can I use JiangTe resin? |
| | Yes, ours are equivalent to Huntsman. Please tell the number of
Huntsman you’re using, we’ll offer the one matching. |
| 7 | What’s the pot life? |
| | Pre-filled resin is one year; Pure resin is 2-3 years. |
| 8 | What's the packing? |
| | Pre-filled resin is in 25kg drums; Pure resin is in 225kg drums; We
also have 5kg drums, IBC tanks and etc. |
| 9 | We’re just starting producing. Can you help us on the process? |
| | No problem, we’ll offer guidance and support. We have thousands of
customer manufacturers in China and overseas. So we have good
experiences. |
