Basic Performance Comparison
Formula 1: B-296 20 g / 3EO-TMPTA 80 g / 1173 2 g
Formula 2: B-113 21 g / TPGDA 49 g / 3EO-TMPTA 30 g / Active Amine 2 g / Initiator 2 g / Flow Control Agent 0.5 g
Formula 3: B-113 30 g / TPGDA 30 g / 3EO-TMPTA 40 g / 1173 3 g
Among these, B-113 is a standard bisphenol A epoxy acrylate; B-296 is a di-functional polyurethane acrylate.
After mixing uniformly according to different formulations, first apply the coating using a 12 μm wire bar, then cure it with a mercury lamp.
Compared with commercially available products, it exhibits similar performance in terms of curing speed, ink hardness, adhesion, UV yellowing, resistance to boiling water, and curing shrinkage rate, meeting the product requirements.
