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.

Els components d'alumini han de rebre un recobriment complet de conversió de cromat en diverses etapes o un pretractament adequat sense crom o una preanodització adequada per netejar i condicionar el substrat. Cal demanar consell detallat al proveïdor del pretractament. El fosfat de ferro i, en particular, la fosfatació de zinc dels metalls ferrosos millora la resistència a la corrosió. Els substrats d'alumini poden requerir un recobriment de conversió de cromat.
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.
| Mètode d’aplicació | Tribo, Electrostatic |
| Reciclatge | Unused powder can be reclaimed using suitable equipment and recycled through the coating system, but a minimum of 70% virgin powder should be used. |
El rendiment real del producte dependrà de les circumstàncies en què s'utilitzi. Els resultats es basen en proves mecàniques i químiques que (tret que s'indiqui el contrari) s'han dut a terme en condicions de laboratori i es donen només com a guia.

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.
| Valor típic | Mètode/estàndard | |
| Resistència química | Excellent resistance to acid, alkalis, oils and chemicals at room temperatures. | |
| Prova de ruixat de sal | Pass, no corrosion creep more than 3 mm from scribe, 500 h | ISO 9227 |
| Valor típic | Mètode/estàndard | |
| Humitat | 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. |
| Preparació de superfícies | 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. |
| Sol·licitud | For repairs a PU (2K or 1K) liquid paint is recommended. |
