Beschreibung
Zusammenfassung:	The invention discloses a UV-light cured water-base urethane resin with the structure general formula as shown in the left formula. The UV-light cured water-base urethane resin leads polyether diol into a polyurethane main chain, a polyurethane chain can be led into more double bonds for crosslinking polymerization by using terminated monomers of hydroxyl acrylic esters, thereby improving the crosslinking and the relative molecular weight of coatings, effectively improving the chemicals resistance of a UV curing water-base system and integrating two properties of hardness and the flexibility.
