Mastic sealant
The sealing of the assembly is ensured by a "sealing" product of the polysulfide, polyurethane, silicone or "hot melt" butyl type, that demonstrates good adhesion to the glass and to the spacer. Note : in the context of CEKAL certification, the type of mastic sealant is the essential element to characterize the process.
