Apart from the sectors described previously in detail, and thanks to the versatility of TECNADIS METALCOAT “Easy-To-Clean”, its application can be extended to other sectors such as the ones listed below:

• Construction and metal structures sector to protect metallic elements against weathering and corrosion.
• Electrical and electronics industry to waterproof and protect electrical contacts and circuits.
• Boiler sector and storage tanks to prevent waste depositions and facilitate cleaning.
• Restoration sector to protect valuable metal parts and monuments from weathering and therefore from corrosion, as well as from deterioration caused by the growth of algae, lichens or mosses.
• Smelting and forged industry to facilitate the cleaning of moulds and auxiliary equipment, as well as to protect them against corrosion.
• Jewellery sector to protect the parts from passivation and the loss of the noble metal bath.
• Livestock industry, equipment and infrastructure for livestock farms, can be protected against corrosion caused either by exposure to the weather or by deposition and dirt generated by animals on farms and feedlots, among others.
• Anticorrosive coatings sector, to protect metal parts such as screws, rivets, springs, bushings, bolts, flanges, valves, among others, as a substitute for or in addition to other treatments, for instance zinc-coated, to increase their corrosion resistance and thus their service life.

SUMMARISING, THANKS TO ITS MULTI-PURPOSE TECHNOLOGY AND VERSATILITY, TECNADIS METALCOAT “Easy-To -Clean” CAN BE USED FOR MANY OTHER KINDS OF MATERIALS AND APPLICATIONS, PROVIDING A COMBINATION OF NON-STICK PERFORMANCE AND PROTECTIVE PROPERTIES.

OTHER REAL APPLICATIONS 

Welding projections

Problem: When welding works are carried out in the manufacture and/or maintenance of metal parts and equipments, the projections generated when welding are stuck to the surface of the metal, in the tools for positioning the parts or even in the nozzles of the welding equipment, being necessary to use tools like scrapers, screwdrivers or spatulas for their elimination. Nowadays, there is a great variety of products on the market, such as silicone-based, water-based, oil-based or ceramic products, some of which present a series of drawbacks that sometimes make them useless for certain sectors. This is the case, for example, of silicone-based products, because they are incompatible with surface treatments such as painting and are highly contaminating, being this reason why in the automobile sector is prohibited the use of any product containing silicon components, and neither they are recommended for their use in welding equipment torches due to the amount of smoke they generate. Water-based products can cause bubbling during welding, affecting the quality of the weld, as pores are created. The oil-based ones avoid the adhesion of the projections thanks to a lubricating effect of the surface, and in a similar manner to the silicone-based products, they are incompatible with the paints, being necessary to eliminate the remains completely before painting. Finally, reggarding ceramic products, it has to be remarked that they are mainly intended for the protection of torches, holders or moulds, among others, not being advisable to use on the pieces because of the white layer they create on the surface.

Application: Tecnadis Metalcoat “Easy-To-Clean” has been applied on AISI 304 stainless steel sheets that after the treatment have been exposed to semi-automatic welding projections.

Results: In order to prove the performance of Tecnadis Metalcoat “Easy-To-Clean” in the welding sector, a test was made in a company specialising in the maintenance of petrochemical industry. This test consisted in placing two stainless steel sheets, one treated with the coating and the other one not treated, welding between them a cord using a semi-automatic welding equipment. After the test, it was checked that the use of the coating does not interfere the process or the final result of the welding. It facilitates the cleaning of the projections generated when welding, being able to remove all the remains out of the treated surface just with a damp cloth, without leaving residues that may affect subsequent protective treatments. In addition, it does not generate gases or additional harmful fumes during the process. In the words of the professional who carried out the tests, who has been engaged in soldering for decades,”I have never seen anything like it”.

ANTI-CORROSIVE COATINGS

Problem: The application of coatings for corrosion protection of fastening elements is a widespread technique, which confers different degrees of protection depending on the type of treatment applied. Among the most common coatings are zinc plating which, although it offers low protection against corrosion, is one of the most commonly used for steel screws due to its versatility and price, since it admits subsequent treatments such as organic/inorganic sealants when it is necessary to increase its protection against corrosion.

Application: Tecnadis Metalcoat “Easy-To-Clean” has been applied in zinc-plated screws of a national reference company dedicated to coat the surface of any type of parts using various treatments.

Results: Tecnadis Metalcoat “Easy-To-Clean” has been applied to screws with zinc plating treatment in order to increase their corrosion resistance and they have been tested in a salt spray chamber at the facilities of this treatment company. The test result has shown that the combination of the zinc plating treatment with Tecnadis Metalcoat “Easy to Clean” has a corrosion resistance of more than 1,200h, as opposed to the 72h resistance of the zinc plating treatment.
