Catalyst 883

Highly reactive adhesion promoter

• Improves adhesion to various substrates
• Accelerates the crosslinking reaction of epoxy resins
• Increases the resistance of the coating
• Optimises processing properties

Catalyst 883 is a specially developed additive to improve the adhesion and performance of epoxy coatings on mineral substrates. It accelerates chemical reactions and optimises the bond between the coating and the substrate, resulting in increased durability and resistance.

Mixing ratio: 5% catalyst after hardener addition

Compatibility and application

Catalyst 883 is specially formulated to optimise the performance of Kronalit Epoxy Primer 819 and Kronalit Epoxy Colour 862. By adding 5% of the catalyst after the hardener has been added, the molecular bond between the coating and the substrate is significantly strengthened. This results in improved adhesion, accelerated cross-linking reaction and increased resistance of the coating, which is particularly advantageous in demanding industrial applications.

Kronalit Epoxy Primer 819: a two-component primer with high resistance to water and chemicals and temperatures up to +140°C.

Kronalit Buntepoxy 862: a universally applicable two-component high-performance coating for heavily used surfaces such as industrial floors with forklift traffic.
