Eporust HT Miox

Two-component anticorrosive epoxy-poliammine primer intermediate MIO

Eporust HT Miox

Primer-intermediate two-component anticorrosive epoxy-polyamine for general use on steel protection, where high service temperature are requested.. This product, based on high molecular weight resins, maintains its performances till 200°C temperature. It has excellent chemical resistance (oils, fuels, detergents, fertilizers) as well as an excellent impact resistance, scratch and abrasion. Such characteristics are improved by the presence of micaceous iron oxide which gives considerable protection by barrier effect. It is used in all cases in which the request is an effective anti-corrosion action, even in severe conditions. Not recommended for continuous immersion service.

Product information

Surface preparation

On sandblasted surfaces apply to almost white metal (2.5), perfectly free of oil, grease, dust, moisture or any other contaminant. The product must be applied strictly on dry surfaces, clean, perfectly free of oil, grease, dust, moisture or other contaminants. The product is applicable even on surfaces that are already primed.

Application methods

Spray, brush or roll. Preferred application is airless spray. Brush or roller don't grant an uniform coverage, use these techniques only on retouch or small surfaces.

Additional information

This is a two-component product. Before mixing the two components it is recommended to homogenize the component possibly with agitator and shake vigorously, possibly without opening, the packaging of component b. After mixing and addition of appropriate thinner, agitation should be continued until it became homogeneous. In order to use the correct mix ratio, necessary to obtain the best results, we recommend to catalyse only entire packs. In case you want to use only a portion of the pack, you should equip with adequate precision scale for catalysis by weight and appropriate sized containers for catalysis by volume. The pot life (time of use after catalysis) is significantly reduced by increase of temperature. Ambient temperature has influence on curing time which, under 10° C is extended considerably. Epoxy products are not suitable to use at low temperatures (typically under 5-8° C), except through the use of a specific catalyst (winter grade). The temperature of the surface to be treated must be at least 3° C higher than the ambient temperature. If this condition is not met the resulting condensation, not always visible, may easily lead to phenomena of non-adherence. The coating requires a period of 7-15 days at 25° C for complete curing. Carefully remove any accumulated roughness prior to the application of subsequent coats. It is recommended to implement all necessary measures (development of equipment for painting, using any thinner retardant-wetting thinner, position yourself upwind, proper progression of the surfaces to be painted) to prevent the accumulation of dust coating, which often causes inhomogeneity of the film.
