Carlfors Bruk AB has supplied the Autoclaved Aerated Concrete (AAC) industry or the Lightweight Concrete industry (LWC) with aluminium flake products for more than 80 years and in that time built up a profound expertise with regard to aluminium powder and paste for this application.
Different forms of aluminium flakes are used in the special auto clave process to produce super thermally insulating concrete building blocks and reinforced panels in various densities and strength classes . The typical pore structure is created by the reaction of the alkaline concrete mass and the aluminium powder or aluminium paste used. We are familiar with most of the different lightweight concrete systems like Siporex, Ytong and Hebel.
We make aluminium powder and aluminium paste to individual customers specific requirements and have a dedicated AAC laboratory which is fully equipped. We also have a specialist AAC engineer to support customers both on and off site which help make Carlfors a world leader in this field.
Superior leafing aluminium paste and non-leafing aluminium paste
Pigments for the coating industry are a core business for Carlfors. We have more than 100 years’ experience in producing pigments for coatings such as Reflective Roof Coatings for domestic and industrial buildings ,Marine Anti Corrosion Coatings for extending the life cycle of ships, Decorative coatings providing superior added value aesthetics to various substrates including textiles and finally for general industrial coatings.
Aluminium flake powder as energy source
Aluminium Flake Powder and Atomized Powder are very effective sources of energy. Carlfors powders for Civil Explosives are widely used for water gels and emulsion applications.
Aluminium pigments with excellent hiding power and brilliant sparkling effect
Carlfors pigments for plastics are offered in three different forms; pellets, paste and powder. Our Silver Dollar pellets are state of the art pigments with a very narrow particle size distribution and provide outstanding brilliant metallic effects. Our flake pastes and pellets are well known for their excellent hiding power at low loading levels. They are supplied in different solvents or plasticizers to suit customers’ requirements.
Organic and inorganic coated Aluminium pigments for powder coating
Powder coating is gaining popularity as a coating technique as it is an environmentally friendly VOC free process. Our range of leafing and non-leafing pigments for powder coatings are appreciated for their good dispersing properties and coverage. The pigments are suitable for both Corona and Tribo powder applications and can be either dry blended or bonded with the base powder coat. Depending on the application and production process we have different pigment encapsulating technologies to offer such as an inorganic encapsulation process where silica coated flakes offer superior spraying characteristics and an organic polymer encapsulation which provides outstanding corrosion resistance.
High quality metallic pigments for inks
Carlfors Silver Dollar pigments for Gravure and Flexo printing inks have superior brilliance and good coverage. Our soft granule is easy to handle and transport. The Silver Dollar products are available for both solvent borne and water borne applications.
Atomized aluminium powder for a wide range of applications
Our atomized powders are manufactured by solidifying an aluminium melt by high pressure air. The nodular aluminium powder is sieved into different fineness. We have a wide range of coatings to be applied to achieve different properties according to our customer’s demands. Atomized powder is for example used for explosives, chemical industry or hot isostatic pressing.
