This is a frozen Kastar Ceramic Tile Sealer sample that has been put into the refrigerator for over 72-hours. Now let’s break the ice with a hammer. We can see that the sample has not deformed and discolored under the condition of freezing temperature. which proofs that Kastar has wonderful low-temperature resistance effect and it will have great performance for places with cold climate. Technically the low-temperature resistance of Kastar can up to – 30 degree after curing.
Smash the cured Kastar Ceramic Tile Sealer sample with an ordinary hammer, as hard as you can try, it still remains intact and without any deformation.
