Color and packaging

JS-8000-E dual component silicone structural sealant main agent and curing agent can be supplied in a set combination (weight ratio 12:1), or purchased separately. Due to the fact that most users need to use the main agent to discharge the glue when using the JS-8000-E product, the main dosage should be proportionally higher when supplying glue

JS-8000-E packaging: main agent 180L, 190L iron bucket, curing agent 18.5L plastic bucket packaging.

Storage and expiration date

When JS-8000-E dual component silicone structural sealant is stored in its original packaging in a dry and ventilated environment at 27 ℃ or lower, the storage period of JS-8000-E products is 12 months from the date of production.
