Construction & Industrial
Bjørn Thorsen distributes a diverse range of specialty chemicals and raw materials from world leading manufacturers, like BYK, Sun Chemical, Honeywell UOP, CH-Polymers, DRT, Trinseo, Cabot, for various areas of the construction industry. We serve the Northern European market, aiming to be the “go-to” industry experts, and the “one-stop shop” solution for our customers looking to create the most qualitative, safe and long lasting construction for their end-customers.
Additives
Additives for construction are specialized components used to modify and optimize the performance of materials such as concrete, mortars, plasters, coatings, and sealants. They enable precise control of properties like workability, setting time, adhesion, water resistance, and durability, ensuring reliable processing and application on-site. By enhancing resistance to environmental stress, moisture, and mechanical wear, additives play a key role in extending the lifespan and performance of construction systems.
Wetting, Dispersing, Surface, Rheology, Wax Additives
Bjørn Thorsen distributes the full portfolio of wetting and dispersing agents, rheology modifiers, surface additives, waxes, defoamers, adhesion promoters and stabilizers from BYK. Wetting and dispersing additives help to incorporate and stabilize pigments and fillers.
Rheology additives, which can be based on urea, polyamide, phyllosilicates, liquid associative thickeners or liquid waxes, in order to establish and optimize the viscosity profile.
Surface additives enable control and coordination of the surface tension and energy on substrate and coating. When correctly managed, it will prevent wetting and levelling issues, as well as surface defects.
Wax additives improve a multitude of surface properties. These can be scratch and abrasion resistant, soft feel, anti-slip, matting and gloss, anti-blocking and structure, etc. We can supply wax additives in liquid emulsions and dispersions, as well as solid micronized wax additives.
Defoamers from BYK
Foam often causes problems in production and application processes. It also has a negative impact on surface coatings such as appearance and mechanical protective effects. In order to achieve the desired defoaming effect, the defoamer should have a certain degree of incompatibility in the system. The defoaming effect is generally based on a combination of hydrophobic particles and an oil component. Most common chemical structures are Mineral Oil, Silicone or Silicone free polymeric defoamers.

Molecular Sieves from Honeywell UOP
Molecular sieves from UOP CH Sárl, a part of Honeywell UOP group, such as: L Powder, L-Paste, 4A Activated Powder are used for moisture absorbents, where water is not desired in a product. This could be in the production of natural and biogases, where water reduces the calorific value which can cause corrosion. Furthermore, the products are used for polyurethane coatings, where moisture makes the coating set hard, before it is intended to harden.
UOP Beads are more sophisticated products, as they absorb other volatile gases such as ammoniac, sulphur, and similar unwanted components.

Pigments
Pigments for construction applications are used to provide durable, consistent color and opacity in materials such as concrete, mortars, plasters, coatings, and paving systems. Inorganic pigments, especially iron oxides and titanium dioxide, are widely used for their excellent UV stability, weather resistance, and compatibility with cementitious and alkaline environments. Beyond aesthetics, pigments also contribute to long-term performance by improving resistance to fading, heat buildup, and environmental exposure in outdoor and structural applications.

Biocides
Biocides for construction are used to protect materials such as paints, renders, sealants, and insulation systems from the growth of mold, algae, bacteria, and fungi. They are essential for both in-can preservation and long-term film protection, especially in humid, exterior, or poorly ventilated environments. By preventing biological degradation and surface contamination, biocides help maintain structural integrity, appearance, and service life of construction materials.
