The aim of the study was to determine the state of metallized coating after five years of operation under the impact of the environment on silnoagressivnoy SNIP 2.03.11.85.
"Natural survey was conducted on thirty sites randomly selected section of the barrier fence. Measurements were made of the total combined thickness of the coating and metallization coating thickness separately. Determined in accordance with GOST 15140 LCP adhesion and bonding strength metallized coating according to GOST 9.304 by applying the grid scratches "- The specialists of" Plakart. "
The study experts found no single plot the destruction of metallization layer. Furthermore, there were no traces of rust even if damage to the paint coating.
