acrylate crosslinkers

allnex acrylate crosslinkers technologies

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

allnex acrylate crosslinkers innovation snapshot

Allnex has produced innovative products for many years, our technical team is constantly working on new innovation projects to provide high performance and environmental friendly products.

Here are some examples of our latest innovations:

• Acrylates for Peroxide Cured Systems

  • Acrylates can be included in systems where free radical polymerization is initiated by peroxides, improving process as well as functional performance. For instance, acrylates are used to improve material performance in MMA waterproofing systems or structural adhesives, where EBECRYL urethane acrylates are added to achieve the required flexibility at low temperatures.

• Acrylates for Michael Addition: epoxy-amine systems and beyond

  • Acrylates can also polymerize via the Michael addition reaction.  By adding acrylates to the epoxy part of an epoxy-amine two-component system, viscosity can be reduced, reactivity can be increased and cured properties can be optimized.
