Metal-containing acrylated oligomers improve overall performance in radiation-curable liquid and hot-melt PSAs
The control has low peel strength of 1.75 lbs-force. All of the hybrid zinc acrylate oligomers improved the 180° peel adhesion, but only two of the tested samples improved the tack as well. The 3% addition of CN2401 and the 6% addition of CN2402 both improved the tack as well as the peel adhesion. In fact, the 6% addition of CN2402 yielded both the highest 180° peel adhesion and tack for this series of samples tested.
