Elbe Coating

A major project of the year 2008: Internal and external coating of 2 bio-ethanol storage tanks the company Prokon Nord Energiesysteme GmbH (acquired by N.prior energy GmbH in the year 2010) built in 2008 two large containers for the production of bioethanol. The tanks have a height of 16.5 metres and a diameter of 16 m. Due to the immediate location of the city Stade in the rivers the air is swingarm and Elbe, as well as its proximity to the North Sea very humid and saline, what extremely promotes the corrosion of steel. Our partner in this project, the company Reinken, is a competent company for extensive blasting and coating techniques since 1980. The company Reinken has specialized on coatings for demanding requirements. So be in the drinking water and food, course approved Beschichtungsmaterialen applied up to 150 C temperature resistance according to the water resources Act or also chemically resistant inner coatings of storage tanks for aggressive media competently and reliably replaced first coated. The Application of external coating: extreme request through increased corrosion risk the structure of large tanks lasted several weeks.

Due to the salty air, already heavily corroded the unprotected steel surfaces. The blast cleaning and external coating of the tank has been now carefully and quickly. Ceramic polymer premium protection systems for exterior Primer: ceramic-polymer STP is a 2-components-ceramic composite coating with specific epoxy binder matrix and active anticorrosive pigments which potentiate the combined effect of the additives. The product can be used as a primer or stand-alone system and offers: Excellent corrosion resistance High impact and abrasion resistance Very good bonding properties 1 Layer system Fulfilment of the ISO standard 12944-2 / category C4 & C5 topcoat: ProGuard 169 is a highly-networked 2-component polyurethane topcoat with excellent colour stability and excellent physical properties: Extreme UV stability and resistance to weathering Excellent abrasion resistance High chemical resistance 1-Layer system, rapid curing Fulfilment of the ISO standard 12944-2 / category C4 & C5 (strong resistance for industrial areas, coastal and offshore areas in aggressive and salty atmospheres.) The photo shows the exterior of the tank after 5 years! The coating is still intact. No signs of weathering or corrosion are visible on the surface.
