Sodium lye (sodium hydroxide in an aqueous solution) is one of the basic raw materials used in almost all industries. The main consumer of sodium lye is the building industry, which uses the product in:

• the process of obtaining liquid glass - a component of high-quality silicon adhesives and paints - from silica
• the production of titanium white, which is one of the basic components of paints,
• the production of synthetic dyes,
• the process of manufacturing specialised surfactants for construction and the building industry as:

- a sodium carrier in the process of synthesis of specialised ionic surfactants,
- a catalyst (reagent) in the ethoxylation and propoxylation process,
- a neutralised (reagent) in the sulfonation process,

• the final stage of the process of production of additives for plastics used, among others, in the building industry as a neutralising agent,
• the production of additives for concrete and cement mortars (superplasticisers, dispersants) as a neutralising substance.

Other uses for sodium lye:

• the synthesis of various organic and inorganic compounds (e.g. as a raw material (sodium carrier) for the production of ionic surfactants),
• the pulp and paper industry (grinding, lignin removal, bleaching of cellulosic pulp, and wastewater treatment processes),
• the processes of obtaining aluminium from bauxites,
• the production of soaps and detergents,
• the neutralisation of acidic waste streams and purification of waste gases from acidic components,
• the textile industry - cotton processing, dyeing of synthetic fibres (such as nylon and polyester),
• water treatment processes,
• the production of dyes and bleaches,
• obtaining artificial silk,
• rubber production and rubber regeneration,
• the mining industry,
• the refining of oil and mineral oils,
• as a laboratory reagent.

Temperature range in which the product's characteristics are not affected: + 10°C to + 60°C, shelf life - no limit if the product is stored properly. At temperatures below + 10°C, the product may solidify; returning to liquid form does not change the physico-chemical properties of the raw material and does not constitute a basis for complaints.
