Bonding agents / crosslinkers
ipox CL - Your adhesion promoter for good adhesion on difficult surfaces.
The ipox CL adhesion promoters are special polyfunctional, aliphatic epoxies. They are also called primers and improve the adhesion performance for heavily stressed or poorly adhering surfaces or coatings (surface treatment). As so-called adhesion bridges, primers thus enable optimum adhesion of coatings, paints or even adhesives when applied to the workpiece. They also increase the network density of coatings - and thus significantly enhance their mechanical properties.
Application areas for adhesion promoters and crosslinkers.
Multifunctional primers and crosslinkers are used in a variety of applications, for example in the electronics, tire, paper and pharmaceutical industries, and as crosslinkers for super adsorbers. Primers are also used in transfer printing for materials that are difficult to print on, in adhesive tapes as a primer for poorly adhering or stressed substrates, and in the automotive industry on bumpers. In the production of Super Adsorbers, these primers are used and applied to improve surface crosslinking. The hydrogels of the Super Adsorbers are more stable and can absorb more water more quickly and are more suitable if they have been surface treated beforehand.

Modifier in epoxy resin formulations.
However, primers are also used as modifiers in epoxy resin formulations to achieve certain end properties and to optimize the end properties of 2-component epoxy resin systems.
Due to their usually higher functionality, adhesion promoters or crosslinkers form a significantly denser network, which leads to special properties of the cured epoxy resin system. Adhesion promoters and crosslinkers have a polymer structure. ipox CL adhesion promoters score with a high chemical resistance to acids and bases, they react actively with the networks formed by the epoxy resin and hardener. Adhesion promoters and crosslinkers are rarely cured with a curing agent alone, as their end properties are usually insufficient.
During processing, adhesion promoters and crosslinkers are added directly to the resin to increase the crosslink density in the cured epoxy resin system.
