4 Our products Aluminium Flake Powder Consistent Aluminium Pigment Powders For A Wide Range Of Applications Our aluminium flake powders are produced in a wet milling process and the drying is done in a vacuum drying process which is our own Carlfors invention. In the drying process the aluminium flakes are allowed to oxidize in a controlled environment to ensure a safe and consistent product for our customers. Our powders are well suited for technical applications like Autoclaved Aerated Concrete, and Civil Explosives, where the choice of lubricant and additives during the milling process gives different characteristics, leafing or non-leafing for the final product. Our products for pigment applications are commonly used in Powder Coatings, Printing Inks, Textile Coatings etc. Aluminium Flake Paste A Wide Range Of Aluminium Pigment Pastes Aluminium pigment pastes are widely used in numerous applications for paints such as Roof Coatings, Marine Coatings, Protective Coatings, Anti-Corrosion Coatings, Decorative Coatings and Industrial Coatings. Depending on the lubricant used in the milling process the aluminium flakes obtain different characteristics. There are in general two different types of aluminium pigments, leafing grades and non-leafing grades. The leafing grades float on the surface of the coating film and the non-leafing grades are uniformly distributed in the coating film. For the Autoclaved Aerated Concrete (AAC) industry or the Light Weight Concrete (LWC) industry we have a complete range of technical aluminium paste grades. Aluminium Pellets Aluminium Pigments In Dust Free Pellets Form The flakes used for our pellets are based on Silver Dollar or corn flake technique. The narrow particle size distribution of the Silver Dollar in combination with the smooth, polished flakes gives an appealing bright metallic appearance. A wide range of particle sizes are available.

6 Coatings Leafing Paste Leafing pastes for coatings give a specular chrome like finish which adds value and substance to the substrate. The coatings can also be functional such as in roof coatings where the leafing finish helps keep buildings cool by reflecting the sun s infrared radiation. This then helps reduce costs in keeping a building cool by reducing the use of air conditioning. Leafing pigments get their distinctive properties from the fatty acid lubricant in the milling process. The non-wetting characteristics of the leafing pigments tends to align the flakes at the surface of the coating film and creating a bright silver finish. Our knowledge and continuous improvements over the years have developed a range of leafing pigments with superior leafing value and very good reflectance. A wide range of solvents are available.

7 Coatings Non-Leafing Paste Non-leafing pigments can be divided into two types: corn flake or Silver Dollar. Corn flake pigments are cost effective and provide very good coverage and a smooth metallic appearance. Silver Dollar pigments consist of individual mirror like platelets and provide superior specular effects which possess very good colour travel from face to flop. Non-leafing pigments are used where good substrate and intercoat adhesion is required. Non-leafing pigments are distributed evenly in the coating film, in contrast to the leafing pigments tendency to align at the surface. The non-leafing effect can be achieved by using unsaturated fatty acids in the milling process or by using leafing pigments with polar solvents. Non-leafing pigments gives less mirror effect in coatings compared to leafing pigments but are easier to top coat. Our CBright Non-leafing grades are cost effective and high brilliant pigment grades for Coil and Can-coating. They are based on corn flake technique and are characterized by good hiding powder.

8 Powder Coating Leafing Surface Treated Our pigments for powder coatings can either be leafing or non-leafing, corn flake or Silver Dollar type. The leafing type pigments are suitable for dry blended or bonded powder coating systems and provide a specular chrome like appearance. The non-leafing type pigments can be encapsulated with either an inorganic silica coating or an organic polymer type coating. The silica coating provides superior spraying characteristics in either Tribo or Corona powder coat systems providing superior charge separation help eliminate problems such as picture framing as well as enhancing the chemical resistance of the metallic appearance. The organic polymer encapsulation of the pigment imparts exceptional chemical resistance to the metallic effect and indeed can be made to meet the International Qualicoat standard for architectural powder coatings if required. The encapsulated pigments can be either bonded or dry blended with the powder coat system.

13 Plastics Pellets Carlfors metallic pellets for plastics are supplied either as Silver Dollar or corn flake pigment types and offer the user dust free dosing. The pigments are supplied in a wax carrier which has a wide compatibility with various polymer systems however other carriers are available on request. The pigments metallic effect provides the polymer with a superior effect at low loading levels without comprising the physical characteristics of the polymer and in some cases even enhances the polymers physical characteristics. The narrow particle size distribution of the Silver Dollar pellets guarantees excellent result and consistency.

14 Explosives Aluminium 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. In Civil Explosives aluminium powder is used to increase the total energy and blast effect and in some application also to increase the sensitivity. Carlfors has a long tradition of supplying powder for the Explosives industry and with our extensive range of products we have a powder for almost every application. The powders can be coated for better performance and chemical resistance. Coated Atomized powder for emulsion explosives and Flake Powder for water gels are tested in our laboratory to comply with our customers demands of chemicalresistance. A special series of flakes are used for initiation systems, non-electric spark ignition systems. A thin coating of aluminium powder inside the initiation tube is applied and the firing impulse is similar to a dust explosion
