allnex acrylate crosslinkers technologies
The use of acrylates, initially designed for radical curing initiated by UV light or EB radiation, is well established and increasingly popular in two non UV/EB reaction mechanisms: free radical crosslinking initiated by peroxides and Michael addition.
Acrylates feature a broad range of chemical structures. By carefully selecting the acrylate(s) to be used in these applications, superior mechanical properties are achieved, and process improvements can be realized by lowering the viscosity, increasing the reactivity and avoiding VOCs.
Polyester acrylates: wide range of viscosities (low to high), cure speed, moderate to high shrinkage.
Epoxy acrylates: very fast cure, high hardness, excellent chemical resistance
Urethane acrylates : versatile, virtually any performance level can be achieved in terms of softness/hardness, flexibility, non-yellowing and cure speeds, with a wide range of viscosities. Aliphatic urethane acrylates are known for their excellent outdoor performance
Amine modified polyether acrylates: reactivity boosters
Multi-Functional Methacrylates (MFMAs) are used as reactive diluents mainly in non-UV application which are built in the polymer network upon reaction
Acrylate monomers are used as reactive diluents in UV/EB formulations that become part of the polymer backbone
