Storage stability
Of all the minerals available on the market today, Imerys calcium carbonates impart the best viscosity profile over time.
Hybrid polymer systems
ImerSeal™ 50S premium PCC confers the best storage stability in low modulus silane-terminated polymer formulations (48% GCC).
Storage stability (%) = extrusion rate after storage / initial extrusion rate
Socal® U1S2-G confers the best storage stability in medium modulus hybrid systems
Storage stability (%) = extrusion rate after storage / initial extrusion rate
Low moisture content and pick-up with time
Typically, for moisture cured adhesive, final adhesive storage stability is impacted by the inherent moisture of the minerals present in the formulation. A mineral of low moisture content and lower moisture pickup is a key consideration in formulating moisture sensitive adhesives and sealants.
Premium coated ImerSeal™ PCC will be more effective than standard coated GCC.
Dextrin adhesive storage stability
Our LiquiCarb™ 90 calcium carbonate in slurry form gives the best storage stability performance in industrial dextrin adhesives. This is directly linked to the high particle fineness of the product. The higher the fineness, the lower the syneresis.
