Wetting Agents
Substrate wetting additives that lower surface tension so the coating reliably wets low-energy and contaminated surfaces without dewetting, edge retraction or craters.
Typical application systems
Chemistry directions
- Substrate wetting agents
- Polyether-modified siloxanes
- Fluorine-modified types
- Anti-crater additives
How it works
By reducing dynamic surface tension these additives let a coating spread over low-energy substrates and overcome contamination spots where the film would otherwise pull back.
What it solves
- Dewetting and edge retraction on low-energy substrates
- Craters from oil or silicone contamination
- Crawling on plastics and treated metal
- Air-draft sensitivity in spray booths
