Installation Method
Mix component A and component B according to the specified weight ratio.
Pour both components into a clean and dry mixing container.
Stir thoroughly until the mixture becomes uniform.
Pour the mixed resin into the required cable joint or encapsulation device.
Allow the resin to cure completely at room temperature.
Storage and Handling
Store in sealed containers in a dry environment.
Once opened, the material should be used completely to avoid contamination.
Mixing containers and tools must remain dry and free from moisture.
Uncured resin residues can be cleaned using suitable solvents.
Solvents must not be mixed with unused or sealed resin components.
Packaging
Standard packaging: customized per project requirements.
Additional packaging sizes and weights are available upon request.
