SACHTOLITH L

SACHTOLITH® L is an uncoated synthetic white pigment produced from very pure zinc sulfide. It has a refractive index of 2.37 (of ZnS), high brightness and neutral hue.
The product is chemically resistant on the pH range between 4 and 12.
Applications
SACHTOLITH® L is suitable for abrasion sensitive systems in a wide range of applications including; automotive brake pads, coatings, inks, plastics and paper.
Low absorption in the near UV range helps increase compatibility with optical brighteners increasing their performance.
Properties at a Glance
– Very good compatibility with optical brighteners
– Low abrasiveness (low Mohs hardness of ca. 3) which can help reduce cylinder and doctor blade wear
– UV cured systems can benefit from complete through-cure, good adhesion, reduced energy uptake and less photo initiator
– Low binder demand allows formulators to easily adjust the viscosity of the coating
