RESICOLOR 480
BI-COMPONENT POLYURETHANE ENAMEL
Two component, coloured polyurethane enamel, with high coating strength; forms a hard, brilliant film that is resistant to scratches, UV light, weather and aggressive chemicals. Specifically for finishing epoxy floors and coatings.
RESICOLOR 480 creates a glossy thermal-hardening film with high hardening power, excellent appearance and mechanical resistance to wear and tear and scratch. It features good resistance to diluted acid and basic solutions, fuels, oils and lubricants.
- Excellent colour fastness in time and towards UV rays and weathering, enabling both indoors and outdoors application;
- Its high covering power allows varnishing with extremely low consumptions;
- Hardening by means of poly-addition and therefore extremely reduced shrinkage;
- Smooth or “orange peel” finishing;
- Fast hardening and commissioning approx 48 hours after application;
- Physical and mechanical characteristics which do not alter in time.

Preparation of the support
The surface to be treated must be clean, healthy, dry, crumbly part and cement grout-free: best adhesion is achieved by hardening it with sand-blasting, sand-papering, acid washing, smoothing or shot-peening treatment. Remove any trace of dust and dirt using an aspirator.
Cement supports affected by rising damp must be treated with two coats of RESICOL 118 (vapour barrier).
Very porous concrete surfaces or surfaces with cracks and Ω (omega) cavities, e.g. forming concrete, must be levelled in advance with RESICOL 100, epoxy adhesive.
Application on metals requires accurate preparation of the support: elimination of oils, fats, varnishes and rust through abrasive process or white metal sanding (SA 2 – SA 3 degree).
Application of the primer or bottom coat
In case of concrete supports, apply an epoxy bottom coat like RESICOLOR 451 (see FINOMIX varnishing cycle sect. 1.1) or AUTOMIX R70-R72 epoxy-cement.
On steel, apply RESICOLOR 425 primer.
Concrete and bricks may be varnished after application of RESICOL 160, a highly penetrating epoxy compound which aids adhesion on very porous materials (200 g/m2consumption) and wait at least 24 hours before applying RESICOLOR 480.
Preparation of the product
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 bucket.
Application
Brush, roller or airless spray apply, one or two coats, with an average consumption per coat of 80 - 120 g/m².
In case of roller applications where there are no strict technical needs, use short hair Mohair rollers specific for polyurethane finishing.
To achieve an averagely anti-slippery surface, add a small amount of glass microspheres.
This product can be diluted with 5% max RESISOLV POLY 40 solvent.
Notes
Application of a new coat of RESICOLOR 480, 48 hours after the previous one, is possible only following sanding with fine abrasive paper, dust suction and washing using solvents.
During the hot season it is recommended not to use the product In the hottest hours of the day and on surfaces that are especially exposed to the sun.
Do not use in conditions of high humidity, during rainy days or with possible rain and in the hours following application.
Presence of water has a negative effect on adhesion: wet foundations must be dried out as much as possible with air or better with gas flame.
Following mixture, the reaction between the two components takes place immediately. Processing time is therefore limited and depends on temperature.

Application with temperatures lower than +5Cº and higher than +30Cº is not recommended.
Full hardening takes place after seven days with a temperature notlower than +20 C°.
After at least 48 hours from application have gone by, it is necessary to sand the surface with abrasive retina disc (120 grain), before proceeding with painting.
To achieve hard and compact films, consumption ranges from 80 to maximum 150 g/m²/coat; higher consumption results in a reduction of surface hardness.
