IMERSEAL 74S is a surface treated, high brightness ground calcium carbonate of marble origin. It has been specifically developed for sealant applications. It brings, among other properties, the right rheology while ensuring a low moisture content which is ideal for sealants used in construction. IMERSEAL 74S has a coating content of 0.9% + 0.2% and residue on sieve of 50ppm which provides optimal viscosity and prevents moisture issues in sealants. These properties of IMERSEAL 74S make it suitable for use in sealants that require durability and longevity in harsh environments like construction sites.
