SPHERILEX® AC 45

NEW

SPHERILEX® AC 45 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 relatively low oil absorption. Due to its unique morphology, it may also enhance film hardness and improve abrasion resistance of the cured coating.

Surface Week 2: Improving Surface Appearance and Durability with SPHERILEX® Particles

This presentation has described how novel SPHERILEX® silica particles can be used to improve the surface appearance and wet scrub, burnish, stain, and metal marking resistance of architectural paints. It was also discussed how to boost the performance of traditional silica matting agents to achieve deep matte wood coatings that have significantly improved scratch, burnish and mar resistance.

This webinar was part of the Surface Weeks.

Unlock new possibilities by using engineered silica in printing inks

Recorded Webinar: 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.

Surface Week 1: Metal Coatings

Recorded Webinar: We were delighted to offer a joint webinar with  Synthomer, one of the world’s leading suppliers of sustainable water-based and differentiated polymer solutions.

This webinar has focused on the importance of pre-treatment of metal surfaces. The session has coved the application of 1K anti-corrosion primers and direct-to-metal (DTM) coatings, highlighting their benefits in protecting against environmental factors. Additionally, we have discussed the film formation process and common surface defects that can impact performance.
