PETRA

PETRA by allnex is a multifunctional pentaerythritol acrylate-based reactive diluent with a high degree of acrylic unsaturation. It finds use in a variety of ultraviolet light (UV) and electron beam (EB) curable coatings and ink systems where a high degree of crosslinking is desired.

• PETRA is a mixture of predominantly the tri- and tetra-acrylate esters of pentaerythritol.
• It exhibits residual hydroxyl content, high acrylate functionality with very low vapor pressure and low relative viscosity.
• UV/EB curable formulated products containing PETRA is characterized by rapid photo response, high cross-link density excellent hardness and excellent chemical resistance.
