Epopaint 750

Surface preparation

The better the preparation of the substrate, better and longer lasting will be the result. For particularly harsh operating conditions we recommend a white metal blasting (grade Sa3). For less severe conditions an almost white metal (grade Sa 2½) is enough. A commercial blasting or alternatively a good quality mechanical cleaning are often acceptable. Completely remove everything that is not tight and compact, such as rust, old paint, contamination from dirt, grease etc. The product must be applied strictly on dry surfaces, clean, perfectly free of oil, grease, dust, moisture or other contaminants. 

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 dew point. If this condition is not met the resulting condensation, not always visible, may easily lead to phenomena of nonadherence. The coating requires a period of 7-15 days at 25° C for complete curing. The over-coating should be performed preferably within two days. After this time, to ensure a secure adhesion of additional coats is recommended to abrade with steel wool or fine sandpaper. As is widely known, the UV rays are able to cause the surface chalking of epoxy coatings causing an aesthetics alteration, which however does not compromise in any way the performance. 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 if not removed causes inhomogeneity of the film. This product, when used as a primer can be recoated with acrylic, polyurethane and epoxy products.
