Properties of pentaerythritol triacrylate

 

Pentaerythritol triacrylate is usually mixed with pentaerythritol tetraacrylate (PETTA) due to difficulty in separation during the synthesis. PETA has certain crystallinity and fast curing speed. The formed cured film is very hard and has good chemical resistance.

There is a side chain hydroxyl group in the molecule. The presence of hydroxyl group enhances the polarity of the molecule and reduces the volatility. In terms of the reaction site, it can be attached to other materials by grafting for the preparation of the composite material. PETA is widely used in many fields such as polymer materials, coatings, inks, elastomers, sealants and adhesives.
