810 STEELKOTE PU FINISH
A semi gloss high solids two component polyurethane finish based on hydroxy acrylate and
aliphatic isocyanate.
Topcoat in epoxy and polyurethane coating systems for applications where high demands are set with respect to colour and gloss retention,
resistance to chemicals and mechanical properties. Due to aesthetic properties, pre-eminently suitable for application on sendzimir zinc-
coated substrates, and industrial objects as machinery, containers, trailers, agricultural equipment, etc.
PROPERTIES
Gloss Silky gloss (35 GU ± 5 at an angle of 60°)
Gloss disclaimer The final gloss level is partly determined by the structure of the substrate and the applied layer thickness
and may in some cases deviate from the above values.
Colour Standard colours (e.g. RAL, NCS)
Volume solids ca. 56 vol.% (mixed product, depends on colour)
VOC ≤ 410 g/l
Density At 20 °C ± 1.20 kg/l (mixed product)
Dry film thickness Standard: 60-100 μm (depends on application process)
Theoretical coverage At a dry film thickness of 60 μm: 9.3 m²/l
Practical coverage The performance in practice depends on various circumstances. As a guideline for airless spraying, for large
dimensions: 70% of the theoretical coverage. For small dimensions: 50% of the theoretical coverage.
Packaging 20 litre cans. Thinner in 25 litre jerry cans and 200 litre drums.
Shelf life In original well shut packaging 12 months, stored inside at temperatures between 5 °C and 40 °C.
Heat resistance Maximum 120 ºC (dry load)
Activator 903V (optional 973V)
Thinner PU5801
PRE-TREATMENT
Steel roughness Blasting profile 40 – 70 μm (1.6 – 2.8 mils) or power tool cleaned to minimum ISO-St3 / SSPC SP3
Untreated steel The surface needs to be pretreated according ISO12944 part 4 § 6.2.3. Remove grease, oil, dirt etc. using an
appropriate cleansing agent, for instance ENVICLEAN PR (for use see product sheet) and a high pressure
spraying pistol. Grit blasting to purity degree Sa 2½ in accordance with ISO 8501-1. After blasting remove all
dust from the entire surface with compressed air which is free of moisture and grease. Apply first coating
layer within 6 hours. In case the final coating layer is applied on the construction site, extra precautions
need to be taken.
Hot dip galvanized The surface needs to be pretreated according ISO12944 part 4 §6.2.3.4.1(sweep blast, with inert grit). See
also NEN5254 for Duplex systems. Remove grease, oil, dirt etc. using an appropriate cleansing agent, for
instance ENVICLEAN PR (for use see product sheet). Lightly blast the entire zinc surface with an inert
blasting agent (grain size: 0.3 - 0.5 mm, blasting pressure: 2.0 - 2.5 bar, nozzle opening: 6 mm minimum).
After blasting, the entire surface must have a uniform flat appearance. Depending on the zinc layer
thickness, in accordance with NEN5254, max. 5 - 10 μm of zinc can be removed. After blasting remove all
dust from the entire surface with compressed air which is free of moisture and grease. Apply first coating
layer within 2 hours.

WORKING PROCESS
Mixture 810 SteelKote PU Finish, 4 parts by volume.
Standard: Activator 903V, 1 part by volume.
Accelerated curing: Activator 973V, 1 part by volume.
Mixing instructions Mix base component and activator intensively, preferably using a mechanical mixing device. The
temperature of the mixed product should at least be 10 °C during application.
Potlife At 20 °C 6-8 hours (mixed product)
Thinning The paint can be applied with various spray equipment. The necessary amount of PU5801 depends on used
equipment, application method and temperature of the mixed product.
Application conditions The temperature should be at least 10 °C to obtain good drying behaviour and curing. The temperature of
the substrate should be at least 3 °C above dew point. Keep application area well ventilated during
application and drying in order to reduce evaporated solvents. This is necessary to acquire good drying
conditions and for the good of the applicators’ health.
Application method Preferably by means of airless or airmix spray equipment. When using brushes, a different film thickness
and possibly inferior flow will be achieved.

The maximum interval is unlimited, provided that the surface is clean and free of grease and/or oil. At a higher film thickness longer drying time should be taken in
account. During drying and curing the relative humidity should remain under 80%. Furthermore, any contact with moisture must be avoided during this period.
ENVIRONMENT AND HEALTH
Labelling In accordance with EU directions 67/548/EEG and in accordance with directives on hazardous materials.
Harmful and irritating in contact with skin, eyes and by inhalation. In case of eye contact, immediately wash
with large amounts of water and contact a medical expert. Do not eat, drink or smoke during application.

TOUCH UP
Touching up of damages or untreated parts at the construction site. Remove grease, oil, dirt etc. using an appropriate cleansing agent, for
instance ENVICLEAN PR (for use see product sheet). Remove the rust from all mechanical damage caused by transport and mounting,
untreated welding strips and welding spots and burns with rotating steel wire brushes, sanding discs or steel wire brushes and coarse
sandpaper to purity degree St3, in accordance with ISO 8501-1.Smooth the transition of cleansed parts to parts with intact coats of paint by
sanding and scraping.After sanding, remove all dust from the entire surface with compressed air which is free of moisture and grease. Then
touch up the object with the entire paint system, as described in this paint advice.Touch up light surface damages only with the product of the
top coat, as described in the paint advice.
