The role of desculation agent in water-based coatings and screening methods (2)
Time of Update: 2020-09-20
3.3 The importance of the storage test in the selection of desiccants In the selection of desticants, it is recommended to do storage tests, because desiccants in the storage process, due to interaction with surfactants, over time, it is possible to reduce deblistering efficiency, so it is recommended that after doing a good initial screening test, the sample storage, by evaluating the ability and compatible performance after storage, and ultimately determine the choice of de bubble agent.
