HI-EPOXY 1482 Zinc-rich Epoxy Primer product description: a two-component zinc-containing epoxy metal primer that forms a hard, abrasion-resistant rust-preventive coating and provides cathodic protection to steel structures; the product offers good application properties, fast drying and good compatibility, with excellent overall system anti-corrosion performance.

Product use: the zinc-containing primer can be combined with a wide range of Nippon Paint products to form anti-corrosion coatings with excellent overall performance, protecting facilities and structures in various corrosive environments; suitable for many industries such as airports, industrial plants, petrochemical plants, bridges and power plants.

Abrasive blast cleaning: abrasive blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6 (SSPC-SP10 gives better results). If the blasted surface has oxidised before coating, it must be re-treated to the specified standard requirements. Surface defects exposed by blasting shall be treated by suitable means such as grinding and filling. A surface roughness of 40–75 µm or above is recommended.

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 abrasive blast cleaned to Sa 2½ (ISO 8501-1:2007). Where local blasting is not possible, power tool cleaning to St3 (ISO 8501-1:2007) may be used.

Repair application of HI-EPOXY1482 Zinc-rich Epoxy Primer may proceed only after surface preparation meets the specified requirements.

Before application of HI-EPOXY1482 Zinc-rich Epoxy Primer, ensure the surfaces to be coated are clean and dry, and application must take place within the specified recoat interval (refer to the application instructions of the relevant product).

The base and hardener must be mixed thoroughly before use.

Application method: brush and roller application is suitable for repair coating in small areas; air spray and airless spray may be used, and airless spray is normally the preferred method. The specified dry film thickness must be achieved.

HI-EPOXY 1482 Zinc-rich Epoxy Primer* Before recoating, the surface shall be free from chalking and contamination, and surface sealing shall be carried out where necessary; prolonged outdoor exposure of the film, zinc salts or contamination on the surface will adversely affect intercoat 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.

Recommended system

The following intermediate coats/topcoats are recommended for use with HI-EPOXY 1482 zinc-rich primer: Intermediate coat

• HI-EPOXY 4485 Epoxy MIO Intermediate Coat
• HI-EPOXY 4405 Epoxy MIO Intermediate Coat
• HI-EPOXY 4480 Epoxy Intermediate Coat/Topcoat

Packaging

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.

Safety precautions ▪ This product is for professional use. Refer to the safety information on the container and in the Safety Data Sheet (SDS) before use.
