In the solid paint, white paint is taken as an example. The amount of titanium dioxide should be sufficient to ensure that the paint film has sufficient capping power. The amount of titanium dioxide should not be lower than 13%, but it is not necessary to be higher than 22%. The situation is the same as solvent-based white paint. Fillers may be added or not added. However, a small amount of filler...

First, pour the glue on the flat glass to observe its rheology, and wiggle it to observe its rheology,If the flow of glue is too fast, it means that the glue is too thin and poor, and too thick is not conducive to bonding. Secondly, with a hand dip to observe its viscosity if you can slowly draw, a little sticky hand is better. Then, pour it on a small piece of glass to observe its film forming ti...
