Vinyl/micaceous iron oxide with rust-inhibitive pigment
High-build coating for protection of steel and galvanised steel in aggressive environments. Tolerant of damp surfaces during application. Typical applications include lighting columns and general industrial plant.
Vinadac HB MIO has a ‘Class O’ Fire Rating when applied to a non-combustible substrate.
Colours available : 41-121 Sage

Other colours to special order
Appearance Of Dried Film : Matt specular finish
Volume Solids : 40%
Dry Film Thickness : Typical : 75 microns
Range : 50-125 microns
Theoretical Coverage : 5.3m² per litre at 75 microns
Drying Time At 20°C :
(will vary with temperature, air movements, etc.) Touch Dry : 2 hours
Film Dry : 3 hours
Overcoat : 3 hours
Packaging : 5, 15 and 20 litre open-top containers
Shelf Life : 2 years or longer in unopened containers when stored under cover in good storage conditions.
Storage : Under cover with temperature range of 5°C to 32°C.
Surface Preparation : Mild steel, clean and free of millscale : Thoroughly degrease using Dacrylate Thinner R5. Apply one coat of Vinaprime 41 HB Anti-Corrosion Primer (Ref: 41-120) to a dry film thickness of 50 microns.
Mild steel, corroded and/or millscale present : Abrasive blasting to ISO 8501-1 SA 2.5 is the preferred method.
Manual clean : Chip, scrape and power wire brush to remove all loose rust, millscale, etc. to ISO 8501-1, ST3. Degrease with Dacrylate Thinner R5. Apply one coat of Vinaprime 41 HB Anti-Corrosion Primer (Ref: 41-120) to a dry film thickness of 50 microns.
Galvanising (new) : Ensure surface is cleaned and dry.
Note : Adhesion may be further improved on certain types of bright galvanising by the use of Mordant Solution.
Galvanising (weathered) : Use stiff brush to remove any deposits of white zinc salts. Wash down with detergent water to remove road salts, etc., rinse and dry off.
Application Conditions : Temperature : Minimum 5°C
Humidity : Less than 90% RH
Application : Brush : Apply using a ‘full’ wet brush. Avoid excessive ‘brushing out. Do not ‘lay-iff’. A wet film thickness of 190 microns will give a dry film thickness of 75 microns.
Roller : As for brush application, taking care to apply specified wet film thickness.
Spray : Vinadac HB MIO can be applied using conventional, airless and HVLP spray methods. 5-10% of Dacrylate Thinner R5 may be required to give optimum spray characteristics.
Brush or roller is the preferred method for use on damp surfaces.
N.B.: Certain products retain solvents for longer periods, which will affect plasticizers within the plastic packaging causing damage to the finish. It is therefore not recommended that finished painted products be wrapped in bubble wrap, plastic sleeves, etc., until coatings are fully cured as this can cause damage to the finish especially when stacked or stored in sunlight/elevated temperatures.
Damage can also occur from condensation caused by fluctuations in temperature consequently causing a ‘greenhouse’ effect within the packaging.
Clean-up : Dacrylate Thinner R5.
