Aluminium Flake PowderConsistent 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 Con-crete, and Civil Explosives, where the choice of lubricant and additives during the milling process gives different characteristics, leafing or non-leafing for the final pro-duct. Our products for pigment applications are commonly used in Powder Coatings, Printing Inks, Textile Coatings etc.

Aluminium Flake PasteA 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, De-corative Coatings and Industrial Coatings.

Depending on the lubricant used in the milling process the aluminium flakes obtain dif-ferent 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 PelletsAluminium 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 par-ticle sizes are available.

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.

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.

Powder Coating

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.

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 chemical resistance.

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..


A Swedish invention

The aerated concrete is a Swedish in-vention. In 1923 Dr Axel Eriksson at the Royal Institute of Technology in Stock-holm made the first successful steam curing of cellular cement products. He combined steam cured cement and the air cured cellular cement products into a unique invention known as Autoclaved Aerated Concrete, AAC. The first indu-stry for production of AAC was built in Sweden in 1929, and now factories are operating all over the world.

In the process the aluminium is used as an expanding agent, added the last few seconds into the slurry, a mixture of fine milled sand, cement, lime, gypsum and water (sometimes also fly ash and blast furnace slag). The slurry is then put into moulds and as the aluminium starts to react the mass is rising, and then harde-ning into what is called Green Mass. The mass is cut into different dimensions for blocks or panels and is finally put into an autoclave for steam curing.

There are many advantages in using AAC as a building material. AAC is an economical, sustainable, solid block that provides thermal and acoustic insulation as well as fire and termite resistance.

Aluminium Laboratory

In our aluminium laboratory we analyse our own production output constantly in order to always deliver material with a high and consistent quality. Every batch is analysed to make sure that our pro-duct is stable.

We also have the possibility to analyse powder samples in order to tailor make products to match the customer’s re-quest. Our standard analyses are Active aluminium, Blaine, Hydrogen evolution test and Particle size. These analyses give a good indication on how the pro-duct will work, but it is not the whole an-swer. To get closer to the truth we can make pilot scale castings in our AAC la-boratory.

Input

Carlfors was one of the first compa-nies to deliver aluminium powder to the Swedish invention. We have a solid knowledge of differences in raw mate-rials and a long experience of working with different production processes in factories all over the world.

Through the years our marketing and technical departments have been wor-king closely with our customers in long-term relationships. We analyse the raw materials and in close cooperation with the customer we develop different reci-pes in order to correspond to each spe-cial factory and their preferences.

AAC Laboratory

Sweden has a history of broad laboratory activity around the AAC industry as the-re have been many factories operating in the country. In 2007 Carlfors acquired the equipment and documentation from these laboratories and established an AAC laboratory on our premises. Here we can prepare raw materials with our ball mills and crushers in order to make small castings (cube to block size). In our pilot plant we can develop new formulas or optimize existing formulas.

This is the cheapest and easiest way to test the suitability of a new raw material for a plant without having to disturb the daily production in the factory. We can then test compressive strength, flexural strength, shrinkage, thermal conductivity and more on the finished product.

Output

The combination of our profound expe-rience and our two laboratories enables us to give qualified help to customers either you have existing production or are starting up new production. Each production plant has its own unique for-mula where the raw materials have an influence on the end product.

In our laboratories we develop an optimal product with properties that meet with the requirements of each individual case. We can also provide cost-effective solu-tions for logistics, education in different areas such as safety, testing methods or whatever your need would be.

Technical Support

We can give you a unique support as we, within the organization, have expe-rience from both producing and testing the aluminium for AAC, as well as pro ducing and developing the AAC product.

We are always ready to visit your facto-ries for testing together with you, or re-ceiving the raw materials to our AAC lab for testing at Carlfors. Since we also have experience of full-scale production we can assist in any factory as troubles-hooters or to make full-scale tests and evaluations of the process flow.
