Minchem Ltd (ACCS Ltd) NEGF30
Minchem NEGF30 is high-performance epoxy-based acid-resistant material designed to provide maximum resistance to aggressive chemical environments. It is typically provided in a two-component format comprising, an epoxy solution and an epoxy-based hardener, with the option of an inert filler powder with varying granulometry to suit the required thickness and application.

- Safety
Adequate ventilation must be provided whilst work is in progress and is compulsory for closed or indoor applications.; The instructions on storage, fire and explosion are to be observed.; No releases to the sewers or drains are to be permitted under any circumstances.; Ventilation is required with special consideration for enclosed or confined areas.; Air movement must be designed to ensure turnover at all locations in work area and adjacent areas to avoid build-up of heavy vapors.

- Coverage
Typical coverage rates on a relatively smooth concrete surface for a Novolac epoxy materials:
- Pot Life
at 20°C - 60mins; at 30°C - 30mins; at 40°C - 15mins; An initial set occurs approximately 4hours after mixing, light foot traffic permissible after 12hours and with a full chemical cure occurring after 5-7days.; The materials should never be exposed to water, steam or chemical environments before a full chemical cure is completed.; Do not mix more material than required by pot-life.; It cannot be reconstituted. Never add unapproved materials to the mix, in particular water.; After mixing spread out on to the surface to avoid self-generated heat.; Large mixed volumes that are not thinned will flash set, becoming extremely hot and producing smoke.
- Advantages
It provides resistance to the majority of concentrated oxidizing acids, such as sulphuric acid to 98%, hydrochloric acid to 36% and phosphoric acid to 85%.; It is also resistant to hydrofluoric acid (with carbon-based filler) and a large number of concentrated alkalis and salts.; By simply adding various filler materials to alter the characteristics of the two-component epoxy solution, means that the Novolac epoxies are exceptionally versatile and can be adjusted, depending on the circumstances and project needs.
