They are made of component parts, that are meticulously considered in the light of the biological harmlessness, they are enviromentally friendly and at the same time have high technical efficiency. The Fluxes contain activator of organic origin. Working parts of the soldering fluxes dissolve, at the temperatures of soldering, the oxides of the soldered metals by strong complex-forming activity and at the same time intensely decrease the surface tension at the interface of soldered metal and melting iron. The fluxes do not contain rosin. Low content of dry matter together with perfect dissolvabilty in water and alcohol facilitates washing of the completed joints. The soldering fluxes are delivered in 1 liter PE bottles or in 10 liters PE canisters.

Among our most significant business partners belong for instance: AGC automotive Czech and Hungary, BRANO a.s., OEZ s.r.o. Letohrad, Česká zbrojovka Uherský Brod, NAVETA s.r.o. Liberec (soldering of stainless components for weaving machines), further also Slovak companies such as SEZ Krompachy a.s.
Our main goal is to secure high standard of our products. It is possible to arrange individual solution of concrete case of soldering by request of a customer.
The flux is intended as for wave soldering of sheet conductors as for hand soldering of copper, nickel, silver and their fusions. The working temperature during the soldering is 243 – 250°C. The preparation NS – 181 has got excellent wettable effects. Soldered places are easily washable by iso-propyl alcohol or by water. The workplace has to be equiped by exhaustion of exhalations. NS - 181 is a liquid flux, which contains an activator of organic origin and its consistency is 950 kg/m3. The preparation is colourless, has neutral nature - pH 7 and does not contain halogens.
The flux is intended for soft soldering of copper, brasses, bronzes, nickel, cadmium, gold, silver, paladium, jack and their fusions by ordinary Sn – Pb solders. The working temperature is 245 – 250 °C. Its high soldering capacity is based on the transfer of the oxide layer of soldered metals to complex dissolvable allied substances. The workplace has to be equiped with exhaustion of exhalations. It is suitable to wash by iso-propyl alcohol after the soldering. The flux is a liquid whose consistency is 800 – 850 kg/m3. It contains an activating agent of an organic origin. The colour of the flux is butterscotch, which is caused by the contained pH detector. The preparation has got pH 4,5.
The flux is intended for soft soldering of aluminium and its fusions by special melting-iron Sn 70 Zn 30 and further for soldering of iron, stainless steels, kanthal and other resistive materials, some hard metals and so on by ordinary Sn Pb melting-irons. It is necessary to keep the working temperature during the soldering of aluminium between 270 – 320 °C. During the soldering of stainless steels the working temperature is between 240 – 250°C with the melting-iron Sn 60 – Pb. It is effective to preheat more substantial objects to 150 – 170°C. Its high soldering effectivity is caused by complex-forming dissolving of surface oxides, by high wetting power and by action of appropriately fixed fluoride ions on soldered metals. The workplace has to be equiped with exhaustion of exhalations.It is suitable to wash by iso-propyl alcohol after the soldering. The flux is a liquid whose consistency is 840 – 860 kg/m3. It contains an activating agent of an organic origin. The colour of the flux is yellow-orange, which is caused by contained pH detector. The preparation has got pH 3.
Epsilon 4 is preparation designated for activation of the surface of copper and brass, which was oxidized before, and it douses the purified surface well. The capacity is 41g CuO/1 litre. The solution works best by the temperature 50 - 80°C. We dive an object only for the time necessary for dissolution of the layer, which was oxidized before. The process is speeded up by stirring. Afterwards we wash down the object with water and dry it off. The preparation is a liquid whose consistency is 1040 – 1080 kg/m3. It does not contain halide ions. It is colourless. It smells like a formic acid. The preparation has got pH 3.
The preparation is intended for soft soldering of copper and sheet conductors. The solution contains detergent which escalates wettable effects of the preparation. The working temperature during the soldering is 240 – 250 °C. The preparation is dissolvable as in water as in alcohols. We recommend iso-propyl alcohol for washing. The working place has to be equiped with exhaustion of exhalations.The preparation is a liquid flux whose consistency is 800 až 850 kg/m3. It does not contain any halide ions. Effective substances are dissolved in iso-propyl alcohol. The colour of the preparation is yellowish, which is caused by contained pH detector. The preparation has got a characteristic odour - alcohol and formic acid like. The value of pH is 5.
The preparation is a liquid flux intended for soft soldering of iron, some stainless steals, resistive materials, copper, bronze, monel and refulgent zinc by ordinary Sn – Pb melting-irons. The working temperature is 250 - 300 °C. Its good soldering capacity is caused by high wetting power and by complex-forming dissolving of surface oxides of soldered metals. Residues after soldering are easily washable by water or by iso-propyl alcohol.The preparation is a liquid flux whose consistency is 850 till 900 kg/m3. Effective substances are dissolved in iso-propyl alcohol. The preparation does not contain rosin. The colour of the preparation is yellowish. The preparation has got a characteristic alcohol odour. The value of pH is 3,5 till 4.
Letol is a reducing soldering solution intended for soft soldering by a tinny melting-iron. It facilitates and improves the quality of soldering of copper, nickel, cobalt, gold, jack, paladium, silver, cadmium and their fusions. It is necessary to wash residues of the flux by a spirit after the soldering. The working place has to be equiped with exhaustion of exhalations.The preparation is a liquid flux whose consistency is 920 až 960 kg/m3. Effective substances are dissolved in ethylalcohol. The preparation contains neither halogens nor rosin. The colour of the preparation is yellowish. The preparation has got a characteristic alcohol smell. The value of pH is 6.
Desmaltol is the preparation intended for direct soldering of conductors which are isolated by polyurethan, polyester, polyamide and epoxide enamels. It also facilitates soldering of conductors which are covered by particularly mechanically and chemically resistent enamels, after their previous, at least partial mechanic violation. When we have thin conductors and high frequency strings it is sufficient for the elimination of the enamel to make wiping movements by the tinned end of the soldering iron. We recommend to wash by spirit after soldering.The preparation is a liquid flux whose consistency is 1 100 - 1 200 kg/m3. Desmaltol contains neither halogens nor rosin. The colour of the preparation is butterscotch. The preparation smells like triethanolamin.
