Two component, semi-glossy basecoat with epoxy resin and polyamide hardener base, guaranteeing excellent adhesion to iron, galvanised sheet, aluminium and other metals. Recommended for protecting metal surfaces generally against corrosion and as a basecoat for structures subjected to severe chemical and physical environmental stress.
RESICOLOR 425 is the ideal primer for an epoxy or polyurethane finishing to be applied on a metal because it features excellent adhesion to iron, galvanized metal sheets and alluminium;
|Viscosity (Brookfield at 23°C)||272||cP|
|A + Bmixture ratio||100 + 20|
Preparation of the support
Sandblast the metal up to SA 2 – 3 degree to achieve ideal adhesion and a cycle with high performance in terms of resistance to saltern fog test.
Preparation of the product
Blend component A alone for a few minuteso; then pour component B into component A and blend at slow speed for 3’ – 5’ using drill with helix/spiral to reduce air inlet as much as possible; during this operation, carefully scrape also the bottom and the sides of the package.
Apply a layer of material in case of dry film thickness between 60 and 80 μm: two layers of product must be applied using roller, brush or spray (with paint gun or airless gun) on a perfectly degreased, clean, rust-free and dry support.
Application is recommended with temperatures between +5°Cand +30°Cand with dry atmospheres (not rainy, nor foggy); Do not apply with temperatures below +5°C, or when there is imminent risk of rain or with high relative humidity, because the product filming process could be discrupted; The product can be diluted with approx. 10 – 15% Resisolv 111; 72 hours after application it is possible to sand-paper before starting to paint.
|Time of use or pot life (*)||> di 2 hours|
|Dust free (tack free) |
|Over-application (**)||12 hours|
(*) it changes according to dilution.
(**) All data refer to an ambient temperature of +20 °C ,50% relative humidity and sufficient; they may change due to thickness and environmental conditions (temperature and humidity).
Approx130 g/m2on sandblaster metal. Approx170 g/m2on concrete
Available in 6 or 30 kgcans (A+B).
If stored in its original, sealed containers in a sheltered place, the product remains unaltered for 18 months if kept in a closed and sheltered environment with a temperature between +10 and +30 Cº.
Primer or bottom layer for anticorrosion protection of metal surfaces in general which are subject to chemical and physical environmental stress before applying RESICOLOR 411-421-421/2-475-480.
