It refers to the time it takes for a single component room temperature vulcanized silicone rubber to lose its adhesion by touching the surface with fingers during the curing process in the atmospheric environment. Normal refers to the time distance during which silicone rubber flat sealant is extruded and air dried under standard conditions, without touching the surface.

It refers to the thickness of the adhesive layer of silicone rubber flat sealant that solidifies from the outside to the inside within a certain period of time after being applied in a fixed mold under standard conditions, such as 2-3mm/24h, 0.6mm/h, etc.

According to the ASTM C1183 specification, the extrusion weight per unit time under specific pressure conditions using Semco tubing and a specific nozzle (diameter 3.2mm) is called extrusion performance.

It refers to applying silicone rubber flat sealant with a certain diameter to the flange surface, then immediately closing it to control the reasonable thickness of the adhesive layer, and then applying air pressure at a certain rate. The maximum pressure it receives is the instant sealing pressure.

It refers to applying silicone rubber flat sealant into a fixed mold, then placing the mold into oil and recording the thickness of the silicone rubber flat sealant that solidifies from the outside to the inside within a certain period of time to characterize the oil curing characteristics of the silicone rubber flat sealant.

It refers to placing the previously glued shear test piece under specific high temperature and high humidity conditions for a certain period of time, then stopping the closure and bonding, stopping the curing under standard conditions for 168 hours, testing its shear strength, and comparing it with the shear strength tested under standard conditions for direct bonding and curing for 168 hours to calculate the strength persistence rate.

It refers to placing uncured silicone rubber flat sealant in a high-temperature environment for a certain period of time, and then still being able to cure under standard conditions, elucidating that silicone rubber flat sealant is stable under this temperature condition. If the thermal stability temperature of the sealant is ≥ 100 ℃, it means that the uncured sealant can still be cured after heating at 100 ℃.
