Product data(Guideline values) *
JT 8068-1 A Liquid and Solvent free modified epoxy resin
| TYPICAL VALUES* |
Viscosity @ 25℃, mPa.s [ISO 12058] .................................................................. 1,500-3,000 Epoxy value, equiv/g [ISO 3001] .............................................................................0.45-0.51 Density @ 25℃ , g/cm3 [ISO 1675] ........................................................................1.13--1.15 Vapor pressure @20°C, pa (knudsen) ...........................................................................<0.01 @60°C, pa(knudsen) ..............................................................................<0.5 Storage life @ 25℃ (sealed container), month ……………………………………………………………..12 |
Remark:In order to prevent the absorption of moisture,please keep epoxy resin in sealed container and storage under normal temperature (about 20 to 25℃).
JT 8068-1 B Modified liquid Epoxy hardener
| TYPICAL VALUES* |
Viscosity @ 25℃, mPa.s [ISO 12058] ............................................................................50-80 Vapour Pressure @ 20℃, mbar( Knudsen)....................................................................Ca.0.5 @ 60℃,mbar(Knudsen) .....................................................................Ca.10 Density @ 25℃ , g/cm3 [ISO 1675] .........................................................................1.19-1.22 Storage life @ 25℃ (sealed container), month …………………………………………………………….12 |
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. |
