Do you know the storage knowledge of the silicone sealant?

Silicone sealant is a silicon rubber in room temperature, with 107 silicon rubber and filler as the main raw material. It is supplemented by cross -linking agents, tactiles, coupling agents, and catalysts mixed in a vacuum state. Reaction to the water in the air reacts to solidify the elastic silicon rubber.

Silicone sealant products have strict requirements on the storage environment. The poor storage environment will reduce the performance of silicone sealant, and even solidify the product. In severe cases, the performance of Siliconone sealant will be lost in one aspect of the performance, which will cause the product to scrap it. In high temperature environments, silicone sealant will accelerate aging, produce a 'restore' phenomenon, some performance will be accelerated, and the shelf life will be shortened. Therefore, the storage temperature has a great impact on the quality of silicone sealant, and the storage temperature is required to not exceed 27 ° C.

In the low temperature environment, too low ambient temperature will crystallize the cross -linked agent and coupling agent in silicone sealant . The crystallization experience will cause poor appearance and uneven local auxiliary. CIT of. Therefore, crystalline silicone sealant cannot be used. In order to prevent the crystallization of silicone sealant , the editor requires that the storage environment should not be lower than -5 ° C.

In a high-humidity environment, the solidization of silicone sealant is solidified when the water is generated. The larger the relative humidity in the storage environment, the faster the solid rate of silicone sealant . The relative humidity of dry glue and storage environment is too direct. The editor requires that the relative humidity of the storage environment is ≤70%. The packaging of hard pipe silicone sealant is PE material. The soft packaging packaging is aluminum film material. Under the same conditions, aluminum film materials are 10 less than the water vapor of PE materials. This is the same glue. The reasons for shorter shelf life should be. Therefore, in the same storage environment, we need to focus on the shelf life of hard packaging products, and the editor requires everyone to strengthen attention.

All in all, silicone sealant products should be stored in dry, ventilated, and cool places. The best storage temperature is between -5 ~ 27 ° C. The best storage humidity is appropriate. The place where the sun is straight. Under normal transport storage conditions, the date of storage is at least 6 months from the date of production.
