Primer Filler

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).

Russian Federation

In our conversation about this market is attended by representatives of major firms that manufacture and sell lacquers, impregnation, and other similar formulations. Eugene Tsynbal – Head of Department of JSC "Neohim." Sergei Tsvetkov – Director of JSC "antiseptic." Sergey Simakov – director of "Koveks", corresponding member of IAELS. Sergei Korytin – Director of "Morning." Certification and Licensing The importance of fire safety means not only specialists but also recognized at the state level. In accordance with the government Russian Federation N 849 of 23 August 1993 not only the production of fireproof materials, and scientific and technical advice on fire safety and expertise to ensure fire safety fall under the type of activity, which requires a state license. Today, any means of fire protection must certify.

And the certificate should be three: a certificate of fire security, certificate and health certificate. If we add two types of licenses for organizations – to work on the production of fire-retardant treatment of materials and structures and the production of fire protection, it becomes understandable that professionals committed to this type of activity, are true professionals. The current system of certification for fire safety enough established, the process Certification is a few years. Normative reference base has been calculated that if you buy all regulatory materials on fire safety, acting to date, then it would take 3.5 thousand rubles (in prices 1998). Introduced on 1 January 1998, the new SNIP 21-01-97 "Fire safety of buildings and structures" in particular establishes requirements for fire protection of buildings and fire technical classification of materials. Construction materials are characterized by only a fire hazard, which in turn is determined by the following five fire-technical characteristics: flammability, combustibility, flame spread over the surface, smoke-forming ability and toxicity. Speaking about the effectiveness of a flame retardant use some special terms, which, although intuitive sense and is understandable, but it sometimes requires clarification.
