Silicone caulk is a high-performing sealant against water and air penetration, having a number of critical properties that make silicone a suitable product for wall and ceiling cladding applications in proximity to foodstuffs.
Low thermal conductivity
Low chemical reactivity
Thermal stability (constancy of properties over a wide temperature range of −100 to 250°C)
The ability to repel water and form watertight seals
