Series 530 | Omnithane

Generic Type Moisture-Cured Aromatic Urethane
Common Usage Aluminum pigmented primer or finish for marginally cleaned steel. Provides excellent abrasion-, moisture-, chemical- and corrosion-resistance. Suitable for use as a topcoat where an aluminum finish is desired. Topcoating provides enhancement of systems and more latitude with color. Compatible with aged coatings, but verify with test patch.
Colors Aluminum
Finish Matte
Topcoats Series 2H, 27, 66, L69, N69, V69, 73, 113, 114, 161, 175, 530, 1028, 1029, 1074, 1074U, 1075, 1075U, 1077
Note: Series 530 must be exterior exposed for one day prior to topcoating with Series 1028 or 1029. Note: Series 530 exterior (sunlight) exposed for 24 hours or longer requires scarification or an intermediate coat of Series 27, 66 or N69 prior to topcoating with itself (530), 73, 175, 1074, 1074U, 1075, 1075U or 1077. Also if exterior exposed for 7 days or longer, 530 requires scarification or an intermediate coat of 27, 66 or N69 prior to topcoating with 113 or 114. The intermediate coat color should be noticeably different but in the same family as the specified topcoat color.
Volume Solids 51.0 ± 2.0%
Recommended DFT 2.0 to 3.0 mils (50 to 75 microns) per coat. Caution: Application at film thicknesses exceeding 3.0 dry mils (75 microns) per coat or at relative humidities above 70% R.H. may cause bubbles to form in the cured film.
Curing Time
Temperature † To Touch To Handle To Recoat
75°F (24°C) 2 hours 3 hours 5 hours
† 50% Relative Humidity
Curing time varies with surface temperature, air movement, humidity and film thickness.
Note: For faster curing, low humidity and low-temperature applications, add No. 44-710 Urethane Accelerator; see separate product data sheet.
