Specialties
Fine and specialty chemicals developed to meet the technical needs of industry: metallurgy, water treatment, effluents, emulsions, plastics, paints, textiles, leather and complex formulations.
Deliver a precise function at the heart of an industrial process
The LAGUERRE Group develops and manufactures innovative products for specific requirements: inhibiting corrosion, controlling scale, separating emulsions, clarifying effluents, adjusting rheology, improving wetting and reducing static electricity.
Act on the key properties of a formulation or process
A specialty chemical generally provides a targeted function, even when used at a low dosage.
Protect materials
Limit corrosion, scale, oxidation and degradation during processing or storage.
Stabilise and disperse
Control particles, pigments, salts, deposits and blend stability.
Create or break an emulsion
Promote the formation of a stable emulsion or efficiently separate two phases.
Optimise application
Modify wetting, viscosity, foam, sedimentation or electrostatic properties.
Find a specialty by function or market
Search for a product reference, function, substrate or sector, then open the card to view its main applications.
