Arexons Car care and maintenance

The importance of car care and treatment with Arexons products

Car care and treatment are not just a matter of aesthetics, but are essential to preserving the performance and longevity of the vehicle. Arexons products represent a point of reference in the automotive maintenance sector, thanks to their ability to respond to specific needs for both the interior and exterior of the car. Using Arexons polish, car wax, dashboard polish and scratch remover means not only restoring shine and protection to the treated surfaces, but also preventing wear and premature aging of the materials. The Arexons universal prewash is essential for removing the most stubborn dirt before any other detailing intervention. Furthermore, the regular use of Arexons additives guarantees the maintenance of optimal engine performance, contributing to the reduction of consumption and harmful emissions. In short, choosing Arexons products for the care of your car means relying on professional solutions that guarantee long-lasting and reliable results over time.

Complete guide to Arexons products for internal and external car maintenance

Car care is a fundamental aspect to guarantee not only an impeccable aesthetic appearance but also to preserve the performance and functionality of the various components over time. Arexons products represent an optimal solution for both internal and external maintenance of the vehicle. Arexons car polish and wax are ideal for protecting and reviving the bodywork, ensuring long-lasting shine and protection from atmospheric agents. For the interior, the Arexons dashboard polisher guarantees deep cleaning, leaving the surfaces soft to the touch and pleasantly scented. Furthermore, with the Arexons scratch remover, small marks and imperfections can be effectively eliminated without the need for professional interventions. As regards mechanical maintenance, the use of Arexons additives is recommended to maintain high engine performance, at the same time improving fuel efficiency and reducing harmful emissions. Finally, the Arexons universal prewash prepares the surface of the car for thorough cleaning, removing the most stubborn dirt and facilitating the subsequent washing phases. Using Arexons car products means choosing quality and reliability for every aspect of caring for your vehicle.

Practical advice for the use of Arexons additives in maintaining engine performance

Arexons products are essential allies for those who want to keep the performance of their engine always at the top. Regularly using Arexons additives can make the difference in the care of the engine, optimizing combustion and reducing wear of internal components. Here are some practical tips: first of all, it is essential to scrupulously follow the instructions on the additive package, as an incorrect dosage may not have the desired effects or, in the worst case scenario, damage the engine. For effective cleaning of the injectors, we recommend using the Arexons injector cleaner additive every 5,000 km or when the first signs of dirt appear such as a drop in performance or difficulty in starting. In the case of diesel engines, the periodic use of the anti-smoke additive helps reduce the production of smoke and particulates, contributing to compliance with environmental regulations and the longevity of the particulate filter (DPF). Finally, let's not forget about the health of the engine during the cold season: the Arexons antifreeze additive ensures effective protection even at very low temperatures, preventing the fuel from freezing and ensuring the vehicle starts. We remind you that correct and constant use of these products not only preserves the mechanical conditions of the car but can also have a positive impact on fuel consumption and harmful emissions.

Under the Metylan brand, Henkel has always offered complete solutions for interior finishing and covering professionals

murals, guaranteeing the highest quality and satisfying every type of need, from gluing wallpapers and coverings to

particular finishes up to the plastering of the wall.

WALL STICKERS

• Wallpaper Adhesives: based on cellulose and synthetic additives, to be mixed in water before use. They are suitable for wallpapers

light and heavy, under wallpapers and vinyl wallpapers. The range also includes products for the preparation of

wall (wallpaper remover) and for finishing (for example, for the application of decorative borders).

• Adhesives for Coatings: ready to use, they are generally based on acrylic resins, fillers, additives or other types of

polymers (depending on the final use). They are ideal for heavy wallpapers, wall and ceiling coverings, insulating panels.

Pattex

Although the Henkel company began selling common wood glue in 1925, Pattex's history begins in 1956 with the revolution in the glue market. After a long collaboration with German artisans, the first contact glue was created, called Pattex, which cured cold. Until then, consumers had had to heat glues before using them, which was laborious and dangerous. Pattex set out to solve the problem and developed a product that could be applied at room temperature, offering a strong, safe and easy to use solution. At first the product was used by shoemakers for shoe repairs but in 1958, it began to spread widely in the woodworking sector, when it also began to be available in bucket format.

A few years later, in 1964, Pattex contact glue also became available in small 125g tubes, a format suitable for domestic use for small repairs around the house. However, the founders of Pattex never stopped improving the product; in 1972 they were able to present the first 'non-drip' contact glue called “Pattex Compact”, specifically designed to avoid smudging during application.

In 1977, Pattex launched the first specific wood glue on the market, "Pattex Legno Express" for 'Do-it-yourself' users, although the "Pattex Legno" product for woodworking professionals had already existed since 1959. Two years later, the next consumer innovation arrived, the first water-resistant wood glue, called “Pattex Legno Idroresistent”.

In 1981, Pattex increased the assortment of glues by introducing thermofusion guns, specifically designed for professional craftsmen (Example florists).

In 1989 Pattex presented a specific glue for fixing objects to walls. With this product it was no longer necessary to stick or keep objects fixed on the wall for hours! Thus was born the new category of mounting adhesives.

In 1994, Pattex increased its wood adhesive offering again with special products for parquet and wooden floors.

Ten years later, in 2001, it was the turn of another revolutionary invention – a two-component epoxy putty called Riparatutto Express which allows you not only to glue broken objects but also to rebuild and/or seal them if necessary.

In 2006, Pattex once again introduced a major innovation to the market: the new generation of mounting adhesives. Now you can even remove objects from the wall after sticking them. The new removable stickers are born, available both in tubes and in pre-cut double-sided adhesive strips.

2007 is the year in which the best repair glue based on Henkel's patented Flextec technology was launched. This glue is resistant to impacts and all extreme gluing conditions and is called “Ripara Extreme”.

In 2010 Pattex relaunched the concept of mounting adhesives by relaunching the Millechiodi range for beginner users. Everyone understands that the days of drills and nails used to affix objects to walls are gone – the new solution is gluing them.

2010 is also the year of the new identity for Pattex.

A new logo, a new claim and a new packaging. The Pattex brand rejuvenates, maintaining its usual strength.

In 2011, the latest new generation universal adhesive, 1005 glue, debuts. This glue, also based on the Flextec technology patented by Henkel, is the most resistant and effective on the market. Suitable for both building and repairing anything in the home, this glue is transparent and suitable for all materials. Its characteristics are certified by TÜV, the main European institute in the field of certifications.
