This product may be applied by the following methods
| Spray: | Apply by air spray or airless spray. |
| Brush: | Recommended for stripe coating and small-area application. Ensure the specified dry film thickness is achieved. To prevent zinc dust settling, continuous mechanical agitation is required during application. |
| Inorganic Copolymer Zinc-Rich Heat-Resistant Coating 540, Component A | 8 parts |
| Inorganic Copolymer Zinc-Rich Heat-Resistant Coating 540, Component B | 1.32 parts |
Component A is a liquid and Component B is dry zinc dust. Shake Component A thoroughly before use. While stirring mechanically, slowly pour the zinc dust into the liquid. Stir until free of lumps and strain through a 60-mesh screen.

JOTUN Thinner No. 28 may be used in place of JOTUN Thinner No. 4 as a fast-evaporating thinner.
Normally no thinning is required. For application under extreme conditions, consult the local JOTUN representative. Do not thin beyond the requirements of local environmental regulations.
| Note | Where the Korean VOC regulation (Clean Air Conservation Act) and its corresponding thinning limits differ from the recommended thinning volume, the former prevails. |

For the maximum recoat interval, refer to the Application Guide (AG) for this product.
The given drying and curing times and overcoating intervals for inorganic zinc silicate are measured at 80% relative humidity during application and curing. Higher relative humidity accelerates curing; curing of this product requires the relative humidity to remain above 50%.
| 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 |

Temperature
| Continuous | Peak | |
| Drying, atmospheric | 540°C | 600 °C |
This product can withstand peak temperatures up to 600 °C (1112 °F). Continuous temperatures above 540 °C will affect the corrosion protection performance of the coating. At higher temperatures, use in combination with a suitable topcoat to extend coating life.
Withstands peak temperatures for a maximum of one hour.
At the above temperatures, protective performance is unaffected, but appearance may be affected.
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.

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 coating, products may show slight colour variation from batch to batch. Such products, and epoxy products used as topcoats, may chalk when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, application quality and product type. Contact your local JOTUN office for further information.
