Jotamastic 95 XT
Jotamastic 95 XT provides excellent anticorrosive protection under challenging environmental conditions, showing good tolerance even in the face of harsh surface conditions and unpredictable application conditions. It is a two-component polyamine-cured surface-tolerant ultra-high-solids high-build epoxy coating, inheriting more than 40 years of anticorrosive protection experience from the Jotamastic series.
Jotamastic 95 XT uses an extreme long-term anticorrosive technology formulation, adhering firmly to a variety of challenging surfaces, performing particularly well on rusted and damp surfaces. It adheres to ultra-high-pressure water-jetted substrates and flash-rusted substrates, and can even be applied directly to damp surfaces or surfaces with condensation. Jotamastic 95 XT has broad climatic adaptability and can be applied at relative humidity up to 95%, extending its application window.
The advanced technology of Jotamastic 95 XT overcomes the challenges of adverse weather conditions. Unlike other primers, it adapts to different humidity levels, making it an ideal maintenance primer under various climatic conditions. It can be used as a primer in atmospheric and immersed environments, and can also be used as a single-coat system.

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.
