Vacseal vacuum sealant is a widely used vacuum sealant, which has good durability and radiation resistance, is safe and environmentally friendly, and does not contain any ozone depleting chemicals. Vacseal vacuum sealant is a silicone liquid resin sealant for agricultural production system, and is specialized in sealing and leak repair in high vacuum and ultra vacuum systems.
Vacseal vacuum sealant can now be used as a mucilage agent and has good adhesion on almost all solid surfaces.
Vacseal vacuum sealant parameters
Working temperature under normal atmospheric pressure: - 200 ℃ to 400 ℃
Operating temperature under vacuum environment: 450 ℃
Shelf life: 3-5 years
Bottle opening shelf life: 1 year
Leakage holes with leakage rate less than 5.2E-3 atm. cc/s (5.2E-4 pa. m3/s) can be sealed
Suitable for all types of optics window Port, penetrator, gauge, CRT Glass Bonding and sealing
Vacseal vacuum sealant has obvious vacuum sealing effect in low temperature environment. In high temperature environment, it takes 30-50 minutes to heat the fixed line to more than 300 ℃, more than an hour to heat it to 260 ℃, and several days or even weeks to heat it in greenhouse.
