Yuan Lei Small Classroom | Do you know the difference between pigment and filler?


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.





1. pigment


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.





2. coating



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.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

Yuan Lei's Little Knowledge | Application Effects of Different Mineral Powder Materials in Coatings


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.

Yuan Lei's Little Knowledge | Characteristics of Mineral Materials


Mineral materials refer to the material products obtained by processing and transforming natural minerals (mainly non-metallic minerals) or rocks as the main raw materials, or minerals or rocks that can be directly used as materials and aim to utilize their main physical and chemical properties. This meaning mainly includes the following four aspects: first, natural minerals and rocks that can be directly utilized or processed to be utilized; Secondly, finished or semi-finished materials made mainly from natural non-metallic minerals and rocks through physical and chemical reactions; Thirdly, artificially synthesized minerals or rocks; Fourthly, the direct utilization targets of these materials are mainly their own physical or chemical properties, not limited to individual chemical elements.
