Polyketone resin is a kind of hard resin with high photostability. It’s non-toxic and light-coloured. And it’s soluble in any solvent used in coating industry except for fatty alkane and water. It also can be mixed and solved with many resins used in paint and ink. So it can raise paint’s and ink’s properties greatly, such as glossinessãÂÂadhesion ãÂÂpigment wettabilityãÂÂhardness of surface layer and system’s solid content. Furthermore, it can reduce system’s viscosity. When it’s applied in adhesives, it can enhance their first adhesivity, especially it’s durable adhesivity.
