Product Description

Hempel Versiline CUI 56990 is a MIO pigmented single component inorganic copolymer coating which cures to form an inert polymer matrix able to resist temperatures up to 650°C/1202°F and thermal shock/cycling in dry or dry/wet service.

Best Uses

Hempel Versiline CUI 56990 is used for long-term protection of hot pipework, equipment and other hot surfaces. Applied directly onto the steel substrate. Specially developed to prevent corrosion under insulation (CUI).


New steel: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Abrasive blasting to near white metal Sa 2½ (ISO 8501-1:2007) with a surface profile corresponding to Rugotest No. 3, BN10a, Keane-Tator Comparator 3.0 G/S, or ISO Comparator Rough Medium (G). After blasting, clean the surface carefully from abrasives and dust.

Repair and maintenance: Remove oil and grease, etc. with suitable detergent. Remove salt and other contaminants by (high pressure) fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to min. St 2, preferably St 3 (minor areas) or by abrasive blasting to min. Sa 2, preferably to Sa 2½. Improved surface preparation will improve the performance of the paint. Recommended surface profile is Rz 75-100 micron/3-4 mils, corresponding to Rugotest No. 3, BN10a, Keane-Tator Comparator, minimum 3.0 G/S, or ISO Comparator, Medium (G). After blasting, clean the surface carefully from abrasives and dust.

Apply only on a dry and clean surface with a temperature min. 3°C/5°F above the dew point to avoid condensation. Use only where application and curing can proceed at temperatures above: 10°C/50°F. Minimum steel temperature: 10°C/50°F. May be applied on to hot substrates up to maximum 200°C/ 392°F. The relative humidity should preferably be 40-60%, maximum 80%.
