Water-borne Inorganic Zinc Shop Primer 1000 (6AA)
This is a two-component, chemically cured water-borne inorganic zinc silicate coating. It is a shop primer specifically designed for excellent welding and fast cutting, thereby reducing weld porosity and back burn. Fast drying and good abrasion resistance make it suitable for stacking shortly after application. Under atmospheric conditions it can be used as a temporary primer during the new construction stage or as a primer in the complete coating system. Suitable for properly prepared carbon steel substrates; recommended for use on automated shop primer lines. It is compatible with advanced welding techniques including MIG, MAG and GFCAW.
Industrial protective coatings:
Suitable for steel plates exposed to corrosivity categories up to very high (VH). Recommended for refineries, power stations, bridges, buildings, mining equipment and general structural steel.
Others
Shop primer type-approved by DNV GL. Other certificates and approvals are available on request.

| Minimum recoat interval | 1 day | |
| Dry/cured to service | 1 day | |
For the maximum recoat interval, refer to the Application Guide (AG) for this product.
Drying and curing times are determined based on temperature and relative humidity, with relative humidity below 75% and dry film thickness within the average DFT range. Lower temperature and humidity and insufficient ventilation will relatively reduce the curing speed.
| Touch Dry | The state at which light finger pressure leaves no mark or stickiness. |
|---|---|
| Walk-on Dry | The minimum time after which the coating allows normal foot traffic without leaving permanent footprints, marks or other physical damage. |
Minimum recoat interval after drying: the recommended minimum interval before applying the next coat.
Dry/cured to service: the minimum time before the coating can be permanently exposed to a specific environment/medium.
| Paint temperature | 23 °C |

Withstands peak temperatures for a maximum of one hour.
At the above temperatures, protective performance is unaffected, but appearance may be affected.
Note: this coating can withstand different immersion temperatures, depending on the specific chemical and whether immersion is continuous or intermittent. Heat resistance is affected by the coating system as a whole. When used with other coatings, ensure that all coatings in the system have similar heat resistance.
Depending on the actual exposure conditions in service, this product may be used with various primers and topcoats. Some reference systems are listed below. For specific systems, contact JOTUN.

In some markets, the stated shelf life may be shortened to comply with local legal requirements. The above is the minimum shelf life; thereafter, testing is required to confirm quality remains acceptable.
For professional use only. Applicators and workers must be trained, experienced, capable and equipped to mix, stir and apply the coating correctly in accordance with JOTUN's technical documents. Applicators and workers must wear appropriate personal protective equipment when using this product. This guidance is provided based on current product knowledge. Any proposed modification to suit site conditions must be approved by the responsible JOTUN representative before use.
Read the safety warnings on the container packaging. Use in well-ventilated conditions. Avoid inhaling spray mist and avoid skin contact. In case of accidental splashes on skin, wash immediately with a suitable cleaner, soap and water. In case of eye contact, rinse thoroughly with water and seek medical attention immediately.
When used primarily as a primer or antifouling, products may show slight colour variation from batch to batch. Likewise, fading and chalking may occur when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, and application quality.
