Aluminium Powder Coating
Powder coating is a system of protection of the aluminum that consists in the application of a coating, either liquid or powder, on the surface of the metal.
As with most metals, precise preparation of the metal surface is essential to ensure the adherence of the coatings applied subsequently, as well as their durability and optimum protection against filiform corrosion.
Alsan offers a wide catalog of products that allows covering each and every one of the pre-treatment stages guaranteeing an excellent preparation of the metal surface.

ACID DEGREASING
Acidic products of very low attack and consumption, specially designed to degrease the surface of aluminum and prepare it for an acidic or alkaline etching process.
Acid Etching
By using acid etching solutions, the pretreatment processes can be shortened, since it is not necessary to neutralize the surface in order to apply conversion layers.
Alkaline Etching
DEGREASING ADDITIVES
Reinforcement degreasing additives for acid and alkaline baths formulated with biodegradable surfactants.
Chromium-based conversion layers
It is the most classic procedure used for the protection of aluminum before the application of the organic coating. Alsan has a complete line of products based on Cr (VI) for the use of this technique.
Free-chrome conversion layers
Given the increasingly restrictive requirements of environmental legislation, chromatic pre-treatments are being largely replaced by chromium-free technologies. Alsan offers a wide range of possibilities to work with ecological products, all of them approved by Qualicoat.

ECOSTRIP®
Exempt from methylene chloride, phenols, N-methylpyrrolidone and other toxic solvents, ECOSTRIP® products are non-flammable and suitable for application on any metal surface. By using ECOSTRIP® it is possible to carry out the stripping process in short times and at moderate temperatures (30-60°C).
