Two component silicone structural sealant
JS-8000-E two component silicone structural sealant is a two component, neutral curing high-performance silicone structural sealant suitable for building curtain walls.
Product features
1. Excellent adhesion to metal materials such as glass, anodized aluminum, and stainless steel for curtain wall substrates;
2. High standard mechanical and physical properties;
3. Neutral curing is non-toxic and non corrosive;
4. Maintain good elasticity and excellent structural strength from -50 ℃ to 150 ℃ after curing;
5. After curing, it has excellent weather resistance characteristics and excellent UV resistance, high temperature and humidity resistance;
6. No batch matching restrictions;
7. The service life of silicone structural adhesive is 25 years

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.
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.
