Surface preparation: Enamels are applied to the primed surface. Under the enamel HV-124 is allowed to use primers according to GOST 9.401.
Surface preparation before applying primers is carried out in accordance with the requirements of the TNP on the product, GOST 9.402 or STB ISO 12944-4.
To avoid moisture condensation, the temperature of the surface to be painted should be above the dew point temperature by at least 3 ° C.
Application: Before applying to the surface using the methods of pneumatic and airless spraying, the enamel is diluted to working viscosity with solvent Р-4А (GOST 7827).
It is allowed to apply enamels by the method of electrostatic spraying (in automatic chambers with the use of anti-warning devices). In this enamel diluted to a working viscosity with the following diluents:
thinner number 1:
– xylene (GOST 9949, GOST 9410) – 40% (by weight);
– diacetone alcohol (TU 6-02-1045) – 25% (by weight);
– ethyl cellosolve (GOST 8313) – 25% (by weight);
– butanol (GOST 5208) – 10% (by weight).
thinner No. 2:
– solvent (GOST 10214) – 50% (by weight);
– xylene (GOST 9949, GOST 9410) – 35% (by weight);
– diacetone alcohol (TU 6-02-1045) – 15% (by weight).
The consumer independently selects the working viscosity depending on the working conditions (ambient temperature in the room, the diameter of the spray nozzle, the working pressure of compressed air, etc.).
In case of storage at low temperatures, the enamel is kept in a warm room before application (to avoid moisture condensation on the painted surface during painting).
Эмали наносят на загрунтованную поверхность в 3 – 4 слоя. Сушка между слоями эмали проводят в течение 30 мин при температуре (20 ± 2) °С. Окончательную сушку покрытия проводят при температуре 60 – 70 °С в течение 3 ч или при температуре (20 ± 2) °С в течение 24 ч.
Толщина высушенной пленки однослойного покрытия должна быть 18 – 23 мкм.
Выдержка покрытия перед эксплуатацией не менее 7 суток.
Для устранения явления «сморщивания», возникающего вследствие применения технологии окрашивания с разрывом во времени между нанесением первого и последующих слоев эмалей ХВ-124, рекомендуется вводить в эмали гуанид Ф (дифенилгуанидин, далее по тексту – ДФГ) по ГОСТ 40-80. При этом указанный разрыв во времени не должен превышать 5 мес.
The introduction of DFG is carried out by mixing enamel with a DFG solution in acetone (GOST 2768-84) immediately before use at a temperature of from 15 ° C to 30 ° C. DFG is introduced in the amount of 1% by weight of undiluted enamel (in terms of dry DFG). Preparation of the DFG solution is carried out at a temperature of from 15 ° C to 30 ° C by dissolving DFG in acetone in a weight ratio of 1: 9.
The consumption of enamels for a single-layer coating is 110-140 g / m2 without taking into account the complexity of the surface to be painted, its preparation, application method, color, personnel qualifications and other factors.
Coating service life: Terms of preserving the protective and decorative properties of the coating in temperate climates – in accordance with GOST 9.074, tropical climate – GOST 9.401, cold climate – GOST 9.404.
The service life of a coating consisting of three layers of XB-124 enamel applied on a primed surface in a temperate climate is at least 3 years.
The service life of the coating consisting of four layers of enamel XB-124, applied to the surface, primed with two layers of primer FL-03K (GOST 9109), in a tropical climate is at least 3 years.
The service life of the coating consisting of three layers of XB-124 enamel, applied on the surface primed with AK-070 primer (GOST 25718) or VL-02 primer (GOST 12707) with aluminum powder, in a cold climate – at least 4 years.
The coating retains its protective and decorative properties while observing the requirements of the TNPA for coating, drying and operation in cold, temperate and tropical climates.
Storage: Enamels should be stored in tightly closed containers, protected from moisture and direct sunlight. Keep away from fire.
Precautionary measures: Persons associated with the paint work must be provided with personal protective equipment in accordance with GOST 12.1.007 and GOST 12.4.068. All work related to the preparation and use of enamels should be carried out in workshops equipped with local and general ventilation. The dried coating does not have a toxic effect on the environment and the human body.
