Water-based primer and enamel – paint materials, synthetic polymers, form sufficiently stable solutions in water. Filler – the dispersion in the binder of pigments and fillers. Fillers are used to repair various defects (pores, cavities, grooves) on the painted surface. Lucky used as such and as semi-finished materials for manufacturing pigmented. Here are the schematic structure of varnishes, enamels, paints, primers and fillers. What is the difference between the enamel from the paint from the primer, and Enamel coating on the filler is prepared, typically based on polish and she has a nice spill and forms a smooth, glossy and hard surface.
The paint is prepared by drying oil more often, sometimes in water emulsions, and she has a bad spill, forms a mat, rather soft cover. The primer is different from the enamel and fillings, and view the content of pigment and filler. In the primer designed to protect the metal pigments are used to prevent the process corrosion. Typically, the pigment content of 50-80% by weight of film forming. In the enamel is administered up to 120% pigment by weight of film-forming to create a good hiding.
In seeking to increase filler 'body' of the material, so to fill the irregularities of the substrate, so the content of the mineral part of it is 200-300% of the mass prisoner cogenerators. Antioxidant – slows or stops the oxidation processes that lead to aging coatings. The mechanism of action based on the ability of antioxidants break off a chain reaction of oxidation. Catalysts – alter or stimulate a chemical reaction. Dispersers (dispersal) – thin grinding of a solid or liquid, resulting in the formation of dispersions: powders, suspensions, emulsions, aerosols. Stabilizers – are introduced into the emulsion to prevent fogging when applied emulsion layers on a substrate. Hardeners – cause hardening of the reactive oligomers. (Oligomers – members of homologous series, occupying a molecular weight region between monomers and macromolecular compounds. By oligomers are many synthetic resins – alkyd, phenol formaldehyde, epoxy).
