GRANUCOL® color quartz sand – the details
GRANUCOL®-SIG/SIL, GRANUCOL®-DURA/SIL and GRANUCOL®-FFB/SIL are colored fillers which consist of a hard mineral core coated with a glass-ceramic like layer containing embedded pigments.
GRANUCOL®-SIG/SIL, GRANUCOL®-DURA/SIL and GRANUCOL®-FFB/SIL have reactive groups on the surface which react with the plastic and form an extremely tight bond between the polymer and the material. The result is an exceptionally tough composite for sinks which homeowners will enjoy having in the kitchen for many years.
