HI-EPOXY 1460 is a two-component, fast-drying, high-build anti-
rust primer, with excellent anti-rust performance and application performance, and good drying and recoating properties in winter application.
As a long-term protective primer with excellent system compatibility, it is used for coating new and maintenance steel structures exposed to various corrosive atmospheric environments, such as bridges, petrochemical facilities, municipal engineering, the power industry, port machinery and mining equipment.

Remove oil and grease in accordance with SSPC-SP1 solvent cleaning.
Abrasive blast cleaning to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6 (or SSPC-SP10 is preferred). If the blasted surface has oxidized before coating, re-blast to meet the specified standard requirements. Surface defects exposed after blasting shall be treated by grinding, filling or other suitable methods. Surface roughness shall be 40–75 µm.
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) or SSPC-SP6.
If local areas cannot be abrasive blasted, mechanical grinding to St3 (ISO 8501-1:2007) is permitted. HI-EPOXY 1460 may be applied only after surface preparation.
Before application of HI-EPOXY 1460, ensure the surface to be coated is clean and dry; application shall be carried out within the specified recoat interval (refer to the relevant product application instructions).
Other surfaces: if this coating is to be applied to other surfaces, consult the local Nippon Paint company for further information.
Application is not recommended when the substrate temperature is above 45 °C or the air relative humidity exceeds 85%; the steel temperature shall
at least 3 °C above the ambient dew point, and ensure good ventilation at the application site.
| Mixing ratio | Base : curing agent = 8:1 (by weight) |

Note* Before recoating, the surface shall be free from chalking and contamination. The above maximum recoat time is set to achieve ideal adhesion. When the film has been exposed outdoors for too long, or the surface is smooth or contaminated, recoat adhesion may be adversely affected; therefore, the film surface shall be subjected to roughening, sweep blasting or high-pressure water jetting to ensure sufficient adhesion. When the temperature remains below 15°C, it is recommended to switch to the winter-grade product for application.
The above data are for reference only; actual overcoating and drying times may be shorter or longer depending on film thickness, ventilation, humidity, coating system and prior hand or mechanical preparation.

Curing agent: 12 months (25 °C). Store in accordance with national regulations. The product shall be kept sealed in a dry, cool and well-ventilated warehouse, away from heat and ignition sources. Excessively high temperatures shorten the storage period and may cause gelling of the paint in the can. The above is the minimum shelf life; beyond this period, testing is required to determine whether the product can still be used.
