Health and Safety

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.

Colour Variation

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.
