JT 8055B contains accelerator. Prolonged storage at high ambient
temperatures results in an undesirable increase in its viscosity
and impairs the reactivity of the system mix. It is sensitive to moisture. Partly emptied containers must be
resealed immediately.
|
Remark Prefilled liquid products always show small filler sedimentation. Before partial use we recommend to stir up carefully the components
or to use each container as complete unity
|
Storage The components have to be stored under dry conditions at 5 - 25°C
in tightly sealed original containers. Under these conditions, the shelf life will
correspond to the expiry date stated on the label. After this date, the product may be
processed only following re-analysis. Partly emptied containers should be closed tightly
immediately after use. For information on waste disposal and hazardous products of
decomposition in the event of fire, refer to the Material Safety Data Sheets (MSDS) for
these particular products.

FAQ:
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
