What Jotamastic 85 is for
Jotamastic 85 is a two-component, high-solids epoxy mastic built for maintenance and repair. It tolerates a range of prepared substrates and aged coatings, has short recoat intervals and can be applied at sub-zero substrate temperatures. That helps in winter shutdowns on the Highveld.
Use it as a primer in atmospheric and immersed environments on carbon steel, galvanised steel, stainless steel, aluminium, concrete and compatible aged coatings.
Typical applications
- Maintenance and repair of refineries, power plants, pipelines, bridges, mining equipment and structural steel
- Primer in atmospheric and immersed environments within a complete system
- Overcoating compatible aged coatings
Limitations to check
- Surface-tolerant doesn't mean no preparation. Prepare substrates as the TDS requires.
- Its ANSI/AWWA C210 reference applies to areas NOT in contact with potable water. Do not use it as a drinking-water lining.
- Chemical and immersion performance depends on the full system and the cargo or exposure.
Get the system right
A coating performs as part of a system: surface preparation, primer, build coats and finish. Send us the specification, substrate and exposure. We'll confirm whether Jotamastic 85 is the right Jotun product, what goes with it, and the availability and lead time for collection in Henley on Klip or delivery around the Vaal Triangle and Johannesburg South.
