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. |
