There is common in our country a system of notation coatings (paints), which reflects their properties, application, operating conditions. When choosing to store any paint or varnish is enough on the rules stated below to decipher the notation on the bank, and you'll know exactly what this material is paint, where it can be used. Each coating materials are given name and designation, consisting of letters and numbers. The designation consists of four lacquer, pigmented material, of the five groups of characters. Enamel, such as enamel PF-115 or SC-132 enamel, and paint are designed for the upper layers of coating, which have high and diverse demands on decorative and resistance to external factors. Used terms 'paint' and 'enamel' is quite similar but not identical. Hear other arguments on the topic with Spurs. The term "primer" refers to a group of materials that constitute a suspension of pigments or their mixtures with fillers in a film-forming material, forming an opaque when dry uniform film. Suspension (Suspension) – a mixture of substances, of which one (solid) is distributed in the form of tiny particles in the other (liquid) in a suspended state.
Primers, such as GF-021 primer, intended to apply the first coating layer, Therefore, it's high demands. They should provide good adhesion of the film (adhesion) with the painted surface and coating materials, inflicted on a first coat (interlayer adhesion). In addition, primer should reliably protect the surface of products and have high corrosion resistance. For this part of the primer introducing special pigments. Filler – highly filled materials that are viscous pasty mass, consisting of a mixture of pigments with fillers in a film-forming substance. Fillers are used to fill irregularities and depressions, smoothing the surface to be painted.
As a rule, filler applied to the pre-primed surface, at least – to the metal. Film-forming substances (paints, varnishes) used in the production of user-friendly paints and their application form – in the form of solutions. Varnishes called a large group of materials that are solutions of film-forming substances in organic solvents or water. After drying, they form a solid transparent (colorless or colored) film. Lucky used to produce transparent coatings, when you need to protect and preserve at the same time (or highlight) the structure of the substrate, mainly of fine wood. In this case, the varnish is applied directly to the prepared surface. Often coatings applied as the final layer in the multilayer coating to give it a good appearance or increase usability. Varnishes – film formers derived from vegetable oils, have undergone special processing (oxidation or prolonged heating at high temperatures), with the addition of driers and solvents. Varnish dries in the air forming a soft elastic films with low mechanical and barrier properties
