Surface Treatment

AKTEK in city has a total of 5.844-sqm space dedicated for surface treatment facilities. There are one dedicated shot blasting (sand and glass, 1.100 sqm) and one dedicated painting facilities (3,744 sqm). / Surface Treatment Facility 3 km.

The Surface Treatment facilities of AKTEK consists of 3 main sections:
– Carbon Steel Abrasive Blasting Halls (including Manual Grit Blasting, Automatic Shot Blasting, and Vacuum Cleaning by Grit)
– Stainless Steel Abrasive Blasting Halls (including Blasting by Glass Bead and Quartz)
– Painting, Coating & Cleaning Halls (inc. Graco Airless Paint Sprays, Metco Metallization Gun, Hot Water Cleaning Unit)

The most common types of paint applied are IOZ (inorganic silicate zinc), various Epoxy types (including Polyamide, Polyamine, Vinyl, Phenolic, Mastic, Coal Tar, Zinc Phosphate), Polyurethane, Acrylic, Alkyds (including Amino-alkyds, Urethane-alkyds) and Silicone based.
In recent years the paint shop has applied very high build coatings (min. 2000 micron) like Barrierpipe and high build high performance polymeric coatings like Belzona.

Flame spraying-metallising-by METCO gun is another process that is applied on request. Moreover the climate inside the paint shop is monitored 24 hrs/day with the help of the Data-logger electronic device that records humidity and temperature
