The Foma Fomaspeed Liquid Emulsion 1 kg + Hardener 15 ml is a chemical for use in photography under RED safelight conditions. For amateur and professional photographers alike, Fomaspeed Emulsion features medium contrast and extremely high covering power which allow you to gain a broad scale of halftones - even by a relatively high yield of 32 - 64 sq ft (3.0 - 6.0 sq m) per 2.2 lb (1.0 kg) of emulsion. For most common applications, especially on smooth surfaces, one layer of emulsion is enough to be spread. One main advantage of this high-speed emulsion is short exposures, which enable large-size enlarging. With most developers, this emulsion produces a neutral to mildly warm image tone.
The emulsion may be spread on many different bases, including wood, textile, glass, china, ceramics, metals, leather, stone, concrete and plaster. The photochemical inactivity of the base is crucial. If this condition cannot be met, the base should be treated with a suitable waterproof layer, such as epoxide varnish. Good wetting power of the base surface is also important to the process. Non-wettable surfaces should be treated with a suitable preparation layer before spreading the emulsion, in order to ensure good coherence of the emulsion to the base.
Warning: It is important that a perfect fixing and an adequately long washing be performed, at best in running water, or the resulting photographic image will not have long-term stability
