Reactive diluents

Our modified epoxy resins are special and highly innovative adaptations of the standard epoxy resins category. With our experience and with the help of our reactive reactive diluents ipox RD, we can realize an immense range of such individual adaptations.

Reactive diluents are low-viscosity, mono- or difunctional, aliphatic or aromatic glycidyl ethers of alcohols and alkylphenols and are used to dilute higher viscosity epoxy resins.

The glycidyl ethers used for this purpose are covalently bonded to the polymer and cannot migrate, unlike commercially available solvents.

By using glycidyl ethers as reactive diluents, the final properties such as viscosity, pot life, wetting of pigments and fillers, flammability and, of course, mechanical properties can be optimized.

Due to the strong diluting effect of reactive diluents, formulations for solvent-free coating materials can be produced.

The particular advantage of using reactive diluents is that they reduce the processing viscosity of the resins. This low processing viscosity supports easy application of the epoxy resin system and significantly improves the final result. The addition of a reactive reactive diluents thus facilitates the processing of the epoxy resin and allows, among other things, the addition of more fillers and improves the wetting behavior on the substrate.

Pure reactive reactive diluents cannot be used alone as resin components, as their final properties are insufficient.

ipox RD reactive diluents are crosslinkers and react with the amine component.  For technical, economic and toxicological reasons, a low proportion of reactive diluents in the epoxy resin is always aimed for.
