CORROTECH ENGINEERING s.r.o. provides highly professional services in the field of surface preparation and application of special coating systems for the most demanding stress environments and various industrial facilities, even in the nuclear power sector. CORROCOAT ZIP E epoxy coating filled with special glass microflakes is the ideal choice of corrosion protection to protect the substrate of the steel structure of the interior parts of fire foam tanks in the long term. Dust-free Sponge-Jet™ technology was used for the abrasive blasting surface preparation due to the client’s requirement to eliminate dust escaping into the surrounding air and the possibility of concurrent work.

CORROCOAT has been successfully fighting corrosion for more than 45 years. It uses innovative mechanical engineering combined with anti-corrosion technology to provide long-term protection for both new and damaged equipment. It uses special composite and structural coatings in conjunction with technical processes to individually address corrosion problems. With a focus on quality, refurbishment procedures are a proven, cost-effective weapon to win the battle against corrosion in the long term.
