- High class ballast tank coating
- Heavy duty, abrasion resistant coating
- Overcoatable by a wide range of epoxy- and polyurethane coatings
- Low VOC
- Applicable by standard heavy duty airless spray equipment in a wide film thickness range
Preparation For 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 minimum Sa 2½ (ISO 8501-1:2007) with a surface profile corresponding to Rugotest No. 3, N9a to N10, preferably BN9a to BN10,
Keane-Tator Comparator, 2.0 G/S or ISO Comparator, Medium (G). Apply immediately after cleaning. All damage of shopprimer and contamination from storage and fabrication should be thoroughly cleaned prior to overcoating. For areas not later to be subject to aggressive exposure surface preparation to be as per normal
Preparation For Ballast Tanks: For PSPC type approved coating, consult separate Application Guide.
Preparation For Stainless Steel: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Ballast tanks of chemical carriers to be abrasive blast cleaned to a uniform, sharp, dense profile (Rugotest No. 3, BN9a, ISO Comparator Medium (G), Keane-Tator Comparator 2.0 G/S) corresponding to Rz minimum 50 micron. Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Welds, burn damage or other areas showing local corrosion to be power tool cleaned to minimum St 3 achieving a uniform, distinct surface profile. Surface preparation is improved by abrasive blast cleaning to Sa 2, preferably Sa 2½. As an alternative to dry cleaning, water jetting to sound, well adhering coat and/or to steel. Intact coat must appear with roughened surface after the water jetting. By water jetting to steel, cleanliness shall be: Wa 2 -Wa 2½ (atmospheric exposure) / minimum Wa 2½ (immersion) (ISO 8501-4:2006). A flash rust degree of maximum M (atmospheric exposure) / M, preferably L (immersion) (ISO 8501-4:2006) is acceptable before application. Feather edges to sound and intact areas. Dust off residues. Touch up to full film thickness.
Use only where application and curing can proceed at temperatures above 15°C/59°F. Maximum relative humidity: 85%. If drying and curing conditions are expected to take place below 10°C/50°F or at higher relative humidity, use: HEMPADUR UNIQ 47743. Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. In confined spaces provide adequate ventilation during application and drying. The temperature of the paint itself should be: 15-25°C/59-77°F. At temperatures below 15°C/59°F mix the components thoroughly and allow the mixture to pre-react before use.
