TECHNICAL OVERVIEW
Stability in Water
As a result of testing the HA coating for water for 7 days, the stability in water is good. because the HA only attracted and swelled the water over time, but it did not melt away in the water.
As a result of testing PVP coating for stability in water, PVP coated product with UV curing has better stability in water than PVP coated product with heat curing method.
