The examination of paints and varnishes and coatings (paintwork materials and paintwork) is carried out in order to determine the chemical composition of the paint and varnish coating, as well as to detect particles of paint and varnish materials and coatings, to determine their nature, chemical composition, type and purpose of paints and varnishes and materials, to identify painted objects by traces, to determine the species and genus.
Issues solved during the examination of paints and varnishes:
- whether there are particles on the object, or traces of layering of the paintwork;
- is this substance a paint, if so, what is its genus, chemical composition, type, brand;
- whether the substance submitted for research belongs to a paintwork or material;
- in what way the paint and varnish coating was applied to this item: factory or handicraft;
- whether the surface of this object has been repainted, if it has been repainted, then what is its original color;
- whether the paintwork of the marked part of the car body matches the paintwork of the rest of the car body;
- Are there paintwork defects on the car, if so, what is their localization and the reason for their occurrence: are they of a production nature or operational?
Examination of paint and varnish coatings is carried out on the basis of a court ruling, investigative authorities. Among other things, we carry out an examination of paint and varnish coatings, which can be carried out on a contractual basis at the request of citizens. As objects of examination of paint and varnish coatings and materials, various objects with a painted surface (doors, safes, windows, vehicles, tools, etc.) and particles of a coloring matter, presumably falling away from them, are most often encountered.
Paints and varnishes are enamels, varnishes, drying oils, putties, primers. Once applied to the surface of the object and dried, they form a hard decorative protective film, which is a paint and varnish coating.
Our experts carry out an examination of such objects:
- vehicles, safes, household items or other painted objects that are instruments of crime or objects of criminal encroachment;
- particles of paints and varnishes and coatings found at the crime scene;
- items that have come into contact with paintwork (for example, clothes with traces of paint);
- individual volumes of bulk or liquid paintwork materials, as well as their components;
- a set of painted objects or paintwork volumes.
The following questions are most often asked before experts:
- whether there are traces or particles of paintwork materials on the presented object;
- whether the particles of paintwork materials submitted for examination, seized from a particular car, have a common nature with the particles of paintwork materials that were found at the scene of the accident;
- whether a complete or partial repainting of the vehicle under study was carried out;
- whether the item was painted with paint that was taken from the suspect;
- what kind of paintwork was used to paint the object before repainting;
- whether the layers found on the victim's clothing are the paintwork of the vehicle;
- whether the object is filled with artistic colors and, if so, what colors;
- whether the studied samples of paintwork materials have one source of origin.
The effectiveness of the examination of paints and varnishes and coatings, as well as the entire investigation, depends on the qualifications of the investigator, interrogator or court, as well as the correct preparation of samples and materials. In the case of the appointment of this examination, it is necessary to correctly outline a number of issues that are subject to resolution, and in addition, to determine the range of materials of the criminal case and material evidence that will be sent for examination. A professional approach is needed to determine the objects that are subject to identification, and to the selection of samples that are subject to expert examination.
The study of paints and varnishes and coatings requires high qualifications from experts and a lot of practical experience. We will provide you with highly qualified assistance in the analysis of paints and varnishes and coatings. Our specialists have all the necessary skills and abilities, as well as experience in conducting such research. By contacting us, you can always be sure of the results of your work.
For research, the latest equipment is used, which allows the examination to be carried out as accurately as possible and in the shortest possible time. This allows you to be confident in the accuracy of your analysis.
The following factors are important for the success of the examination:
- the object of research was quickly detected and did not undergo changes (repainting or replacement of parts);
- it is not the scrapings of paints and varnishes and coatings of the object that are examined, but the object itself;
- it is important that all parts of the object's paintwork, seized at the scene of the incident, were presented for examination.
