| Solids content (by volume), % | 65±2% |
| Density | 1.9~2.0 kg/L. Surfaces to be coated must be clean, dry and free from contamination. Surface assessment and cleaning standards refer to surface treatment ISO 8504. Cleaning of oil and grease should refer to SSPC-SP1 solvent cleaning. |
Blast cleaning: blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6 (or SSPC-SP10 for better results). If the blasted surface has oxidised before coating, it must be re-prepared to the specified standard. Surface defects exposed after blasting should be treated by grinding, filling or other appropriate methods.
Shop-primed surfaces: the product may be used over unrusted inorganic zinc silicate shop primer; before coating, welds and damaged areas shall be blast-cleaned to Sa2½ (ISO 8501-1:2007) / SSPC-SP6 (or SSPC-SP10 for better results). If the shop primer shows extensive breakdown or heavy rusting, the whole surface shall be blast-cleaned.
Repair of damaged areas: damaged areas must be blast cleaned to Sa 2½ (ISO 8501-1:2007). If local areas cannot be blasted, mechanical grinding to St 3 (ISO 8501-1:2007) is acceptable. Only after the surface preparation meets the specified requirements may repair application of HI-EPOXY 1494G Epoxy Zinc-Rich Primer proceed.
Before applying HI-EPOXY 1494G Epoxy Zinc-Rich Primer, ensure the surface to be coated is clean and dry, and apply within the specified recoating interval (refer to the relevant product application instructions).
Application conditions: application is not recommended when the ambient temperature is above 45 °C or the relative humidity is above 85%; the steel plate temperature must be at least 3 °C above the ambient dew point.
| Application guide — mixing | Base : curing agent = 13:1 (by weight) |
|---|
The base and curing agent must be thoroughly mixed before use.
| Pot life | 6 h (25 °C). After mixing, it should be used within the pot life. |
|---|---|
| Theoretical Spreading Rate | 0.22~0.23 kg/m² (based on 75 µm dry film) |
| Thinner | Thinner 0941: the amount of thinning shall not exceed the range permitted by local regulations. |
| Application method: brush | Applicable: for stripe coating and small-area application; |
| Airless Spray | Recommended: for large-area application; |
| Air Spray | Not recommended. Regardless of the method, the specified dry film thickness must be achieved. |
| Application parameters — airless spray | Nozzle size: 0.017″-0.021″ |
| Nozzle pressure | 150- kg/cm² |
| Typical film thickness | 60-80 µm dry film thickness: 90-125 µm wet film thickness. Drying time: wet film 150 µm |

| Maximum recoat time * | - | - |
HI-EPOXY 1494G Epoxy Zinc-Rich Primer: *before recoating, the surface must be free from chalking and contamination, and surface sealing should be carried out if necessary; when the film has been exposed outdoors for too long, or the surface is smooth or contaminated, this will adversely affect recoating adhesion, so the film surface must be abraded, sweep blasted or high-pressure water jetted to ensure adequate adhesion.
The above data are for reference only; actual overcoating and drying times may be shorter or longer depending on film thickness, ventilation, humidity, the underlying coating system and prior hand or mechanical preparation. The coating system parameter table provided with the recommended coating system will cover all application parameters and special process conditions.

|---|
Curing agent: 12 months (25 °C). Store in accordance with national regulations. Keep the product sealed in a dry, cool, well-ventilated store away from heat and sources of ignition. High temperatures shorten the storage period and may cause the paint to gel in the container. The above is the minimum shelf life; thereafter, testing is required to confirm the product is still usable.
