Soda lye (sodium hydroxide in water solution) is one of the basic chemical raw materials, which is used in almost all branches of industry. The main recipient of soda lye is the construction industry, which uses the product in:

  • the process of obtaining water glass from silica, which is a component of high-quality silicone adhesives and paints,
  • production of titanium white, which is one of the basic components of paints,
  • production of synthetic dyes,
  • in the process of producing specialist surfactants for the construction and construction industry as:

- sodium carrier in the synthesis of specialized ionic surfactants, - catalyst (reagent) for the ethoxylation and propoxylation process, - neutralizer (reagent) for the sulfonation process,

  • the final stage of the production process of additives for plastics used, among others, in construction, as a neutralizing agent,
  • production of additives for concrete and cement mortars (superplasticizers, dispersants) as a neutralizing substance.

Other uses of soda lye:

  • processes for obtaining aluminum from bauxites,
  • neutralization of acidic waste streams and purification of waste gases from acidic components,
  • obtaining artificial silk,
  • rubber production and rubber regeneration,
  • mining industry,
  • refining crude oil and mineral oils,
  • content of the main ingredient about 35%
  • CAS - 1310-73-2
