Alkaline and acidic cleaners remove oils, grease and residues from the aluminium surface — including natural oils or even polishing pastes.
Alkaline etching removes oxides and creates a matt aluminium surface, whether decorative (E6) or non-decorative (E0). A broad range of Alfisatin additives delivers an excellent matt finish and simultaneously enables extended bath life, simple process control, and high throughput – even when processing high-alloy aluminum.
High effective acid concentrates, with or without nitrates, guarantee brilliant satin-finish to high-gloss aluminium surfaces – including special electrochemical polishing processes.
Acid deoxidising/desmutting removes smut and alloy residues after the etching process, creating a clean, active surface for the anodised layer – no more visible stains.
Additives for sulphuric acid anodising baths modify the oxide layer to improve following colouring processes or meet special hardness requirements, reduce energy consumption and allow to work at higher aluminium concentration.
Electrolytical colouring processes ranging from decorative bronze and black tones, through grey and copper tones, to wood and earth tones for architectural applications or decorative elements. Not to mention the lightfast gold colouring and vibrant Alumino® dyes.
Either traditional hot sealing at 96 °C, which prevents fingerprints, or a special medium-temperature sealing process that saves heating energy whilst ensuring a high quality of sealing – approved by Qualanod.
Nickel-based or heavy metal free cold sealing at ambient temperature plus ageing — saves heat energy and sealing time while keeping good sealing quality.
Liquid acidic cleaner with low metal removal, particularly suitable for cleaning tasks before chemical polishing processes, also for polishing paste removal. Even suitable for electrolytical cleaning. Automatically dosable.
Weakly alkaline cleaner, free of borates, for general cleaning requirements using the immersion method.
Liquipower cleaner, weakly alkaline, great cleaning performance even for special requirements, long lifetime, low in required concentration, automatically dosable.
Weakly alkaline cleaner, free of borates, good for general cleaning requirements, automatically dosable, wide in concentration range and no borates inside.
Liquipower cleaner, weakly alkaline, liquid, for removal of natural oils and polishing paste, excellent cleaning purposes, very low concentration required, borate and phosphate free, automatically dosable.
Liquid standard additive for stabilising alkaline E0 etching bathes (e.g. used for reworking).
Liquid additive for stabilising and activating die cleaners.
Liquid additive for decorative E6 long-term etching at lower aluminium contents.
Liquid additive for decorative E6 long-term etching with higher aluminium contents.
Liquid additive for decorative E6 long-term etching with very high aluminium content, optimised draining properties and low foaming tendency, very matt finish.
Properties like Alfisatin 339/4, but further developed especially for higher alloyed aluminium surfaces, very matt finish.
Chemical brightening process, contains nitric acid, achieves a high gloss level.
Chemical brightening process without nitric acid, produces a decorative satin glossy finish.
Electrochemical polishing process without nitric acid, a high gloss level is achieved using direct current.
To improve the desmutting effect in sulphuric acid-based bathes (e.g. consumed anodising bath solution), no rinsing steps after required.
Powder product for improving the desmutting effect in bathes based on sulphuric acid or nitric acid, particularly effective when using high-alloy aluminium grades.
Additive for the typical GSX process at elevated bath temperatures, supports colouring.
The ENSAVAL process enables both a hard anodising-like layer at low bath temperatures and energy savings when operating above 21 °C. At the same time, colourability is improved at higher temperatures. The process is authorised for use by the Qualanod quality association (P-A023).
Products available as ready-to-use-mixes (e.g. Alficolor 677) or as single stabilisers (e.g. Alficolor 697 + tin sulphate), different variants for cold to warm colour nuances.
Electrolytical Alfisteel process — Produces light to medium grey tones. The surfaces appear to be made of stainless steel.
Electrolytical Decor-GreyAL process — For particularly decorative, dark grey colouring on anodised aluminium surfaces.
Electrolytical Terra-ColorAL process — Enables the production of numerous light to dark brown shades that correspond to wood or earth colours.
Electrolytical Copper-ColorAL process — Enables typical copper colouring on anodised aluminium surfaces.
Inorganic gold colouring, liquid product, automatically dosable, for intensive gold colouring with good light fastness.
Dip colours based on organic components, available in many vibrant colours (like black, yellow, blue, red, green, brown…).
Hot sealing additive for shortened sealing times of up to 1 min/μm.
Standard hot sealing process with good filterability and excellent anti-fingerprint properties. Long service life.
Hot sealing with very good weight loss test values and filterability. Ideal for use in combination with organic Alumino dyes and Wetting agent 31.
A highly durable sealing additive, also suitable for use in municipal water supplies. Smut free surfaces, good sealing quality and easy to use.
Medium-temperature sealing for energy saving, easy to analyse, Qualanod approval (P-S022).
An automatically dosable nickel-based cold-compaction additive. Suitable for use in the architectural sector, for example. Based on nickel salts.
Combination process consisting of cold sealing and post-treatment, improves the alkali resistance of anodised aluminium. Particularly suitable for automotive applications.
A cold sealing combination which is completely free of heavy metals and low in waste water pollution. The development was promoted by the Federal Ministry for Economic Affairs and Energy (ZIM project).
