This special pouring-grade sealant is for use in freezer stores where the operating temperature can be as low as -30°C. Permaflex FS is specifically designed to be placed in the joint when the slab has reached its operating temperature (i.e. it will cure at -30°C). At this temperature the material exhibits Shore A hardness of 65, which provides some arris support. Should the freezer store be taken back to ambient temperature, the material will soften and compress as the temperature increases. Upon drawing the temperature back down to -30°C, the material will revert to its original width as the joint re-opens.
