Five elements to pay attention to when choosing a defoamer for water-based coatings!

In the coatings industry, especially water-based coatings, water-based coating desiccants are used to help eliminate large amounts of foam that may affect paint quality during coating production. And everyone, especially just selected water-based paint special desiccant manufacturers, not necessarily clear in the selection and use of some places to pay attention to, the following and listen to the small editor for you to come.
, to choose those with excellent stability, strong anti-foaming ability and will not affect the paint product gloss of water-based paint-specific desiccant

.
, to detect whether it affects the re-painting performance
here the editor recommends that you use high-speed mixing methods. Set the speed of the machine, the amount of stirring time and viscosity, etc. , compared to the same height of foam elimination time and the length of anti-foaming time.
, water-based paint special deblistering agent addition is generally 0.1 to 0.3%, it is not recommended to add too much, because it may cause adverse reactions, such as the production of shrink holes, oil flowers and other issues.
, can also be used from the speed and stirring time, adhesion and foam height, etc. to determine whether the right water-based paint special defrost.
5, most water-based paint deblistering agent can not be directly added to the diluted water-based paint, it is best to add when the viscosity of the coating / resin is relatively high and the first time added in the abrasive, the second time in the paint, the dosage of 1/2 each.
above is to choose the use of water-based paint special desiccant to pay attention to some places, I hope you can all help.
