KY-915 two-component special silicone sealant for chimney
1, product introduction
KY-915 is room temperature curing two-component adhesive.
2, product features

The product has excellent resistance to temperature change and ultraviolet light, perfect anti-aging property; faster whole curing speed, which is suitable for large area using. It also has excellent adhesion, therefore has better sealing ability, effective moistureproof, waterproof and with good acid resistance, can be use for a long time during-50 °C ~ 250 °C.
3 main technical indices,
23°C±2°C acid leaching 7 days
1), weighing A and B under the using proportion, and fully mixing them. (before it pls using small sample to do test on curing time)
2), operation time can be adjusted (about 1 ~ 2 h), fully cure need 24 h. The higher temperature and humidity, the faster curing speed.
3), during the initial curing, which will produce little ethanol, after the ethanol completely volatile, the performances of the gule can reach to the standards. (the whole time of above is about seven days)
4), B component should be stored airtightly after using. The longer team B stored, the slower curing becomes.
5, the product application
use in the chimney insulation, corrosion, adhesive and pipe heat preservation.
6, packaging and shipment
1). with clean airtight plastic or tinplated jars.
2). Container A components 25 kg/barrel. Team B 2.5 kg/barrels.
3). shipment according to the non-dangerous goods.
