As we all know, in many cases, our floor coatings need to be dyed, but the coloring of floor coatings is simpler than that of ordinary architectural decorative coatings, and the varieties used are relatively small. But from the floor paintActualConsidering the performance requirements, it is best to choose inorganic pigments or water-based color pastes with good chemical resistance and alkali resistance.But there are still a lot of people for the floor coloring in the end is the choice of pigment or filler? The following is the color of the professional staff for you to detail the difference between pigments and fillers.
PigmentsYesIn addition to color and covering effect, epoxy anti-static floor paint sometimes also plays a role in rust prevention. Therefore, epoxy anti-static primer can choose some pigments with certain anti-rust ability, such as iron oxide red, zinc phosphate, tetrabasic zinc yellow, etc. Epoxy anti-static topcoat selects titanium dioxide, carbon black, Hansha yellow, Taijing series pigments, etc. These pigments have excellent chemical medium resistance.
The filler is a low refractive index white and colorless pigment. Most of these materials are natural products and industrial by-products, so the price is much cheaper than colored pigments. The refractive index of the filler is generally between 1.45 and 1.7.
Some fillers such as light calcium carbonate, white carbon black and other small density, suspension force is better, in the coating can prevent the high density pigment precipitation; some fillers can improve the physical and chemical properties of the coating film; some fillers can improve the coating water resistance, durability and wear resistance.
In short, if the choice of fillerWe have to choose the correct filler in the production of coatings, which can not only reduce production costs, but also improve product quality.
Silicates: silica, talc, kaolin, wollastonite powder, mica powder, bentonite, diatomite, etc.
