BUILT FOR THE JOB

A single-component route for steel maintenance

NOVORUST 2550 DTM combines priming and finishing functions in an air-drying modified alkyd coating. It is intended for properly prepared steel where a direct-to-metal system is suitable for the exposure and required finish.

Choose it when avoiding separate hardener dosing and reducing the number of coating products is valuable. Surface preparation, film build and the return-to-service schedule remain essential; a single product does not remove those controls.

Before you specify: For direct application to steel, the TDS requires at least 120 µm dry film. Its general film-build table also lists 80–100 µm overall; do not use that lower figure for the stated DTM steel requirement. Confirm the project specification with NOVOL.

System & application notes

One-component air-drying alkyd coating. No separate hardener is specified. Follow the TDS for permitted thinning and application method.

Substrates: Steel cleaned to Sa 2½ or St3, free of contamination, rust and loose material; old coatings and polyester laminates matted and degreased.
Thinner: THIN 50, 0–10% by volume relative to base; weight ratio base:thinner100:0–9.
Dry film: Steel minimum120µm. English table separately says overall80–100µm; inconsistent, so do not advertise80–100µm as adequate total steel protection.
Application: Pneumatic or air-assisted airless;1–2 coats. Climate+10…+35°C, RH≤80%, dry surface≥3°C above dew point.
Drying at20°C: Dust-free1.5h; operating hardness8h. Second row2.5h is also labelled dust-free and remains ambiguous; do not relabel tack-free without clarification.
Intercoat flash-off: 5–10min.

For direct application to steel, the TDS requires at least 120 µm dry film. Its general film-build table also lists 80–100 µm overall; do not use that lower figure for the stated DTM steel requirement. Confirm the project specification with NOVOL. Operating hardness at 20°C is 8 h; this does not establish full cure or permission to load a waste container.
