Interfine® 979
Description

High performance, two component, high solids inorganic hybrid finish with offers compliance to all VOC legislation and contains no free isocyanates. Interfine 979 significantly improves upon the gloss and colour retention exhibited by typical polyurethane finishes as well as offering improvement in gloss and colour retention when compared to first generation epoxy modified polysiloxane finishes. Interfine 979 also displays the same corrosion resistance and has mechanical properties when compared to traditional epoxy technology.

Interfine 979 is part of International's premium range of polysiloxane finishes. 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. It is intended for use in market sectors where visual impact is important and the need for a high 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.

The dual benefits of corrosion protection and high cosmetic appearance afforded by Interfine 979 mean that as well as exhibiting superior durability, this product also serves as an effective barrier coat similar to a traditional epoxy intermediate and, as such, allows a reduction in the total number of coats required from a multi-coat high performance system - saving application costs and improving productivity during application.
