Sigma Cover 280
This Product is a two component polyamide cured epoxy primer. This product is ideal for steel and non-ferrous metals, as it provides good adhesion, as well as water corrosion resistance. Sigma Cover 280 can be used on Galvanised steel which is why it is used on System N9. (Protective system for galvanised steel- polyurethane topcoat).
System N9 as previously mentioned can then be over coated with either Sigmadur 550/520 (550 = Gloss / 520= Semi Gloss) These topcoats are UV and weather resistant thus making it ideal for use in areas with harsh atmospheric conditions. This product can also be applied in temperatures down to -5 °c which means its non-chalking.
Sigmadur 540, formerly Amercoat 440HS, is a two component epoxy acrylic finish. This product uses higher level of colour and gloss retention so that over a longer period of time and will not fade or wear out like other conventional paints. This coating is used in specification M20!
