Описание товара
MT-100 is a series epoxy based powder coatings that exhibit excellent corrosion protection and chemical resistance when applied over a properly prepared metal substrate. MT-100 is designed for interior application only. MT-100 powders are available in gloss, satin, matt and texture finishes in a wide range of colors.

Предварительная обработка
Aluminium components should receive a full multi-stage chromate conversion coating or suitable chrome-free pre-treatment or suitable pre-anodising to clean and condition the substrate. Detailed advice should be sought from the pre-treatment supplier. Iron phosphate and particularly Zinc phosphating of ferrous metals improves corrosion resistance. Aluminium substrates may require a chromate conversion coating.
Заполнитель
Powders can be applied by manual or automatic electrostatic spray equipment. Applicators and fabricators are advised to use a single batch for parts that will be assembled together. Differences are more likely with special effect powders. Bonded products have better application properties than blended products (more stable) but attention should still be paid to line settings in order to avoid “marble effect” and changes in aspect after recycling. Different substrates (aluminium, steel, galvanized steel…), use of primer, and big changes in film thickness may give a different aspect. Products with different codes should not be mixed even if same colour and gloss. It is recommended that for consistent application and appearance product be fluidized during application.
| Способ применения | Tribo, Electrostatic |
| Утилизация | Unused powder can be reclaimed using suitable equipment and recycled through the coating system, but a minimum of 70% virgin powder should be used. |
Условия испытаний
Actual product performance will depend upon the circumstances under which the product is used. The results are based on mechanical and chemical tests which (unless otherwise indicated) have been carried out under laboratory conditions and are given for guidance only.

| График отверждения | 5 min at 200°C (object temperature) |
| Толщина пленки | 60 - 70μm |
Механические испытания
| Типичное значение | Метод/стандарт | |
| прилипание | Класс 0 | ISO 2409 (штриховка 2 мм) |
| Банки Эриксена | Проход 5 мм | стандартами качества ISO 1520 |
| Гибкость | Проход 5 мм | стандартами качества ISO 1519 |

Chemical and durability tests
Whilst maintaining the general protective and anti-corrosive properties of powder coatings, aluminum and copper/bronze metallic finishes, when submitted to the listed tests, may rapidly show a loss of metallic aspect. The results shown are based on tests which (unless otherwise indicated) have been carried out under laboratory conditions and are given for advice only, actual performance depends upon the circumstances under which the product is used.
| Типичное значение | Метод/стандарт | |
| Химическая устойчивость | Excellent resistance to acid, alkalis, oils and chemicals at room temperatures. | |
| Соль спрей тест | Pass, no corrosion creep more than 3 mm from scribe, 500 h | стандартами качества ISO 9227 |
Environmental and durability tests
| Типичное значение | Метод/стандарт | |
| Влажность | Pass – no blistering or loss of gloss, 1000 h | ISO 6270-2 CH (Constant humidity) |
| Exterior durability | Some chalking and loss of gloss after 3-6 months continuous outdoor exposure. Protective properties retained. Not recommended for outdoor applications. |
Ремонт
| Подготовка поверхности | Damaged areas must be clean and free of grease or rust. Dry-sand the area with 600 grade paper down to the substrate. The area must be completely free of dust and cleaned with a non-aggressive solvent before proceeding. Any damage of the coating system must be repaired as soon as possible. |
| Заполнитель | For repairs a PU (2K or 1K) liquid paint is recommended. |
