Additive

SPHERILEX® AC 45 HS

NEW
SPHERILEX® AC 45 HS is a spherical precipitated calcium silicate designed to improve corrosion resistance when added to a coating formulation. It has a typical calcium content (CaO%) of between 6.5-7.5% and a higher oil absorption than SPHERILEX® AC 45. Due to its unique morphology, it may also enhance film hardness and improve abrasion resistance of the cured coating.

Unlock new possibilities by using engineered silica in printing inks

Recording from September 19th, 2023

As the printing industry advances towards higher printing speeds and a broader range of graphic effects, the utilization of both fumed and precipitated silica in printing inks has become prevalent. The choice of particle sizes and surface treatments plays a crucial role in influencing the ink formulation's matting effect and rheology behavior. This presentation aims to explore the benefits of using engineered silicas such as AEROSIL®, ACEMATT®, SIPERNAT®, and SPHERILEX® in printing inks applications. The discussion will focus on how these silicas can enhance key properties like Rheology Control, Matting, Anti-block, and scratch resistance in the ink formulations.
