Adhesion Promoter 3P434
Description
Primer 3P434 is a solvent-based, single-component primer formulated with special polymers for steel substrates. It ensures excellent adhesion between the substrate and subsequent coatings while drying exceptionally quickly. Thanks to its thin-film application and short drying time, it enables rapid production processes. The primer can be applied by brush, roller, or spray and serves as a reliable bonding bridge in the coating system.
Recommended use
- Adhesion bridge between the steel substrate and subsequent coatings
- Priming of Blasted Steel Components (Sa 2½ in accordance with EN ISO 12944-4)
- Thin-film pretreatment in industrial coating processes with short cycle times
- Application using brush, roller, and compressed air/airless spray methods
