(3) Foaming is still at the stirring speed, which prolongs the mixing time;

(4) The pigments and fillers cannot be fully wetted;

(5) It also causes dissatisfaction and uneven weight in the continuous filling production line;

(6) There are pits, small holes, etc. on the coating film during use.

3. Analysis of the types of defoamers for real stone paint coatings

(1) Tributyl phosphate is more expensive, has poor foam suppression and cannot be stirred, otherwise it will regenerate foam.
