JS-8800 high-performance two 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-8800 product, the main dosage should be proportionally higher when supplying glue.
JS-8800 packaging: main agent 180L, 190L iron bucket, curing agent 18.5L plastic bucket packaging.
When JS-8800 high-performance two 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-8800 products is 12 months from the date of production.
