OCCA Weekly Webinar - Multi-Functional Dispersing Additive for the Wetting and Stabilization of Pigments
Venue: Webinar
Date: Wednesday 10th December 2025
Time: 14:30 – 15:30
OCCA Weekly Webinars Series 17 continues with "Multi-Functional Dispersing Additive for the Wetting and Stabilization of Pigments" presented by Sebastian Dziki of Borchers. The webinar will take place via Zoom on Wednesday 10 December at 2:30pm.
Abstract:
Dispersing agents are essential components in modern coating formulations. They improve the stability, performance, and durability of coatings by preventing particle agglomeration and settling. While they are critical for wetting and stabilizing pigments, dispersants can sometimes negatively impact corrosion resistance and other performance properties. This makes dispersant selection especially critical in waterborne systems, where achieving reliable corrosion protection—particularly in Direct-to-Metal (DTM) applications—remains a challenge.
This webinar will provide a brief overview of dispersant chemistry and function, followed by results from a recent technical study evaluating Borchi Gen 1750 in various waterborne systems, including acrylic- and alkyd-based, pigmented DTM coatings. The presentation will highlight how this dispersant influences corrosion resistance, film durability, and overall coating performance. Comparative data will be shared across different resin systems, offering practical insights for formulators seeking to balance pigment stabilization and good color with long-term protective properties.
