Question:

Dear expert, I am now eager to develop a new water-based paint mainly for wood. The problem that needs to be solved urgently is the drying time of water-based paint. I want his dry time to be in 30 seconds, can you achieve excuse me, excuse me be colophony its key effect.

Response:
Hello, the dry time of water - based paint has two concepts commonly."Surface dryness" refers to the basic dryness when touched, while "actual dryness" describes the state in which water completely evaporates.For your problem, I guess you are referring to the dry surface time of the paint. Usually the surface is required to evaporate at least 80% of the water.The evaporation rate of water is slower than that of solvent-based paints. This is a physical property that cannot be changed.The only way to speed up the evaporation rate of water is to bake. Our experience is that for a 20 micron thick film, the substrate temperature is above 150C, and it is possible to evaporate and dry most of the water in about 60 seconds, which is generally unrealistic for wood.
The type of resin does have an effect on the drying rate.Such as Sinograce Chemical of Special resin polymer for Acrylic Industrial coatings PF - 136 is outstanding in terms of quick drying.But the best resin is unmatched by the 30-second indicator you mentioned.

I do not know why you "dry time within 30 seconds" requirements? Is it possible to extend the drying time by changing the process?You can also check out our blog for a special article on how to achieve quick drying in recipes.
