| Recommended dry film thickness | 50–60 µm, depending on coating system | |
| Theoretical Spreading Rate | 11.2 m²/L at 50 µm | |
| Touch dry time | 1 h | At 20 °C |
| Recoat Interval | Minimum: 6 h. *Maximum: unlimited | |
| Full cure time | 4 days | (component data) |
| Shelf life (cool, dry place) | At least 24 months. *See attached table | |
| Recommended substrate condition and temperature | - Previous coat: the surface (epoxy or polyurethane) should be dry and free of contaminants, and |
if necessary abrade to achieve sufficient surface roughness - Application and curing temperatures down to -5 °C are allowed provided the substrate is free of water or ice - The substrate temperature must be at least 3 °C above the dew point - Maximum 85% relative humidity during application and curing - The coating must not be exposed to rain or condensation too early, otherwise its colour and gloss will be affected
| Instructions for use | Mixing ratio by volume: base : hardener = 88:12 - After mixing base and hardener, the temperature should be above 10 °C, otherwise add thinner to reach the application viscosity. November 2012 - The thinner should be added after mixing the components - Excessive thinner reduces sag resistance |

Pot life (at application viscosity): 10 °C 6 h; 20 °C 4 h; 30 °C 3 h; 40 °C 2 h. |
|---|---|
| Application Methods | - Polyurethane topcoats have high gloss and thin film, and ideal atomization is not easy to achieve - High-pressure airless spray is widely used for such topcoats, but improper configuration of small nozzle and high pressure can easily cause over-thick film. |
- A better application method is air spray with a pressurized lid or pressure feed (e.g. Airmix), which controls dry film thickness better, improves the surface appearance and reduces overspray.
| Worldwide applicability | Although PPG always strives to supply identical products to users worldwide, sometimes minor adjustments to specific products are required to comply with local/national regulations or environmental conditions. |
