SACHTOLITH® HD-S is a white pigment based on synthetic zinc sulfide obtained from highly purified solutions. The product is chemically resistant on the pH range between 4 and 12. The Benefits of the Product Include: – Retention of mechanical properties in glass-fiber-reinforced plastics – Very good compatibility with optical brighteners – Low abrasiveness (due to ZnS based low Mohs hardness of ca. 3) helps 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 adjust the viscosity of the coating – Relatively high thermal conductivity when used in polyolefins which can help protect polymers against thermal degradation
