Frequently asked questions

What is Polyurethane UHB7 — 1 A&b — Protea A58SANS 5L used for?

High-performance two-component polyurethane topcoat for industrial and commercial metal surfaces requiring maximum durability, UV resistance, and chemical resistance. Used in demanding exterior industrial environments. Requires mixing with hardener before application. Suitable for steel structures, plant equipment, and heavy machinery.

Which surfaces can Polyurethane UHB7 — 1 A&b — Protea A58SANS 5L be applied to?

Suitable substrates include metal, mild steel, galvanised steel, previously painted.

Does Polyurethane UHB7 — 1 A&b — Protea A58SANS 5L need a primer?

Yes — it needs a 2K polyurethane or epoxy high-build primer. The Marindec technical data sheet specifies Armourthane 2K (7:1) High Build Primer or Armourpoxy 2K (4:1) High Build Primer. Do not use a single-pack alkyd primer under it. These primers are not listed on the site: ask for one with your quote. Request a 2K high-build primer

What thinner should I use with Polyurethane UHB7 — 1 A&b — Protea A58SANS 5L?

Per the Marindec technical data sheet: Not recommended; if required use Armourthane 2K Thinner. For cleaning, use Armourthane 2K Cleaning Thinner.

What film thickness should Polyurethane UHB7 — 1 A&b — Protea A58SANS 5L be applied at?

The technical data sheet recommends 35 to 45 µm DFT (75 to 95 µm WFT).

What should I know before applying Polyurethane UHB7 — 1 A&b — Protea A58SANS 5L?

2-component system: requires hardener. High-performance UV-stable finish.

How quickly does Polyurethane UHB7 — 1 A&b — Protea A58SANS 5L dry?

Per the Marindec technical data sheet: touch dry ± 3 hours, hard dry ± 8 hours and full cure ± 7 days at 23 °C. Drying times vary with temperature and film thickness.

What coverage does Polyurethane UHB7 — 1 A&b — Protea A58SANS 5L give?
