Calcite
in Adhesive / Sealants Applications :
Wolkem’s Calcite is used in the manufacture of
adhesives & sealants as cost effective filler.
Calcite extends extra ordinary results in different
Silylated Polyurethane (SPU) Sealants, those are
based on different polymers like Silicons, Polycrylates,
Polyurethanes and Polysulfides etc.
Calcite increases the strength of the Sealant
due to its higher specific surface area. This
increases tear strength among all finer fillers,
this can be loaded at high PHRs. Resulting in
significant reduction in polymer demand, GCC also
reduces the dispersing time of sealant. GCC increases
specific surface area for better mechanical properties
and slump resistance leads to general rheological
behaviors. |
