It is intended for use in areas where the highest standard of cosmetic appearance is required. These include high performance constructions such as bridges, offshore structures and tank farms in addition to general industrial and commercial steelwork where high levels of cosmetic performance are a key requirement.


Interfine 979 is a patented high durability, two component, isocyanate-free polysiloxane finish, with outstanding colour and gloss retention. A tough and hard wearing finish, Interfine 979 displays similar corrosion resistance to a traditional epoxy intermediate.

Features and Benefits:

  • High performance, two component, high solids inorganic hybrid finish with offers compliance to all VOC legislation and contains no free isocyanates.
  • Offering improvement in gloss and colour retention when compared to first generation epoxy modified polysiloxane finishes.
  • Displays the same corrosion resistance and mechanical properties when compared to traditional epoxy technology.
  • It is designed to provide excellent long-term colour and gloss retention and provide extended lifetime to first maintenance when utilised as part of a high performance anti-corrosive system.
  • The dual benefits of corrosion protection and high cosmetic appearance afforded by Interfine 979 mean that there is a reduction in the total number of coats required from a multi-coat high performance system.
