The Technical Design of UV Curable Polyurethane Dispersions |
| 초록 |
UV curable polyurethane dispersions(UV-PUDs) have been synthesized from polyisocyanate and ether type polyol with different types of capping agent (2-hydroxyethylacrylate (HEA), pentaerythritol triacrylate(PETA), aminopropyl triethoxy silane (APTES)) and prepolymer chain length (Mp). The PUD cast films were tack free prior to cure and UV cure provided the film with high solvent and yellowing resistances, and high surface properties together with high mechanical strength.As APTES partially replaces HEA gel fraction and Tg decreased due to the decreased crosslink density, whereas hardness and contact angle increased due to the filler and hydrophobic nature of the silicon compound. Notably, the thermal degradation temperature of the UV-PUD has been increased by about 30-40℃ with at 3% APTES. |
