Ultraviolet varnishes got their name because they harden under the influence of ultraviolet radiation. They do not contain volatile components that are often the cause of allergies. They include acrylate oligomers, acrylate -polymers and photographicians. The first group of Acrylate substances determines the viscous structure of UV LAK. The latter provide unsurpassed resistance to the varnish coating, a pleasant glossy shine and resistance to abrasion. The third group affects the rate of hardening of the varnish. It is thanks to these components of the UV LAK for literally a few seconds that forms a strong, glossy coating with a high degree of wear resistance, this is especially appreciated in the institutions of the hospitality industry, many hotels next to the Alexander Neva Lavra only buy furniture covered with UV varnish.
Specialists in paintwork materials distinguish between two types of ultraviolet varnishes: radical and cation. Radical varnishes harden immediately, and cationic varnishes after a few hours or even days. This difference is due to the fact that when radical ultraviolet varnishes drying out, they break up into compounds that form a polymer film. And the photographic and cationic ultraviolet photographs of the cationic type start the process of solidification after the acids that affect the binding substances begin to decline in their composition. The managers containing hotels near the Isaac’s Cathedral always have the contacts of workshops engaged in the coating of UV Laca, spoiled furniture must be restored in a few hours, its appearance will again delight the eye of the guests.
Today UV Lac is an alternative to paintwork on an organic basis that contain solvents. Varnishes of this type are used in the furniture industry, for painting plastics and polymers, metals and wood. The main advantages of varnishes are as follows: high dry residue, excellent mechanical strength, the composition does not include organic solvents, the varnish dries very quickly, is economically consumed, protects metals from corrosion. All these positive points allow you to have a high competitive advantage and a wide scope of use: hotels near the Kazan Cathedral, shipping, educational institutions, and so on. The only drawback of such varnishes is that for working with them a special drying device should be used, which not only emitted UV radiation, but also diverted the rays and the emitted ozone from the personnel working with it.
