Pentaerythritol Tetraacrylate (PETA)

Pentaerythritol Tetraacrylate (PETA)

Description

Pentaerythritol Tetraacrylate is a high-quality industrial chemical widely used in coatings, adhesives, inks, resins, plastics, and specialty formulations. It offers reliable performance, chemical stability, and consistent processing characteristics, making it suitable for modern manufacturing and advanced industrial applications.

Uses

UV-curable coatings/inks/adhesives; crosslinker.

Benefits

High crosslink density; improves hardness/chemical resistance.

Application Benefits

Enhances crosslink density for better hardness, chemical resistance, and abrasion performance. (Typical for Pentaerythritol Tetraacrylate applications.)

Product Description
Pentaerythritol Tetraacrylate is a reactive (meth)acrylate component used as a diluent/crosslinker in radiation‑curable formulations to balance viscosity, cure speed, and final film properties.
