In 2013, thanks to improved coating technology, its abrasion resistance was more than doubled.
Thus, the color difference coefficient (∆E) of a two-layer paint-and-lacquer coating of ALUTECH profiles is less than 1 *. As a result, the roller shutters produced by the company have a uniform and stable color without the "zebra" effect.
Tests have shown that the ideal appearance of ALUTECH roller shutters is maintained for more than four years of daily use: the curtain can withstand 3000 lifting and lowering cycles without the appearance of abrasions. Moreover, the coating is durable and durable even in coastal zones and in a polluted environment, which is confirmed by tests in a salt fog chamber.
Laboratory studies have shown that the paint and varnish coating of ALUTECH profiles is resistant to aggressive media (solvent vapors, alkalis, etc.). Dust and sand that gets on the canvas during operation and can accumulate between the lamellas will also not harm it.
Roller shutter systems "ALUTECH" will emerge victorious from any fight with an aggressive environment. All supporting certificates and test reports can be found on the company's website.
* The effect of "zebra" is caused by the low quality of color profiles, when the color difference coefficient (delta E) between the profiles reaches 3 or more. The fact is that the human eye catches a color difference already at dE = 1, that is, at an indicator exceeding 3, the color difference is noticeable even at a great distance.
