Adoption of this crosslinking mode could markedly improve water resistance, solvent resistance, glossiness and hardness of the film. 6.5w % DAAM out of total monomer mass was preferred.

The wear mass loss is high when the abrasive medium has high hardness, multilayer coating shows better wear properties than single-layer coating in the effect of biggish load.

The result showed that when photo-initiator 184 and photo-initiator 1173 were mixed 2:1 by mass, the coating has high pencil hardness and excellent abrasion resistance.
