(7) Squeezability: This is an item of sealant construction performance. It is used to indicate the ease of use of the sealant. Too thick glue is poor in extrusion properties, and it is very laborious to use. But if the glue is made too thin simply considering extrusion properties, it will affect the thixotropy of the sealant. The extrudability can be measured by a method prescribed by a national standard.
(8) Thixotropy: This is another item of sealant construction performance. Thixotropy is the antonym of fluidity, which means that the sealant will change its shape only under a certain pressure. It can be maintained without external force. Shape without flowing. The determination of the sag according to national standards is the judgment of the thixotropy of the sealant.
