Jotun Introduces N e w M o d i f i ed Epoxy Brush-On C o a t i n g For U n s h o t b l a s t e d Steel Surfaces

Jotun has introduced a new two-pack modified epoxy coating specially formulated for application by brush, roller or spray, to steel surfaces that cannot be shotblasted or otherwise carefully prepared. Known as "Jotamastic," the new product can be applied over existing coatings of many kinds, and is suitable for overpainting by many other products.

Jotamastic contains aluminum, which helps to reflect heat, increases water resistance, and gives the coating a pleasing metallic-gray color.

It has a high solids content of 86 percent by volume, and a dry film thickness of 200 micron is possible with a single coat on steel. The coating can also be used on concrete.

The new product can be readily applied by brush or roller provided the existing surface is reasonably clean and dry, and it will adhere to and upgrade the existing coatings, including weathered primers. It is also suitable for application by airless spray when thinned 15 percent by volume with suitable thinners.

Jotamastic is easily overcoatable and it dries to touch in five hours. It is ideal for cargo holds since it can overcoat the existing alkyd paints commonly used, thereby upgrading to an epoxy system, it is also approved by the North of England Industrial Health Services as an interior surface coating for the storage holds of grain transporters.
