Manufacturer Overview 

The first British Standard assessment was achieved by Aithon Ricerche more than 25 ago.
It was 1990, and the assessment, issued by WFRC, regarded a thin film, water borne intumescent coating for steelwork that achieved 90 minutes.

In 2001 Aithon Ricerche decided to begin to work for itself, approaching the markets with the AITHON brand, quite unknown at that time. At the beginning the sales were concentrated in the home market, but the diffusion of the European Standards offered the opportunity to expand the business; the company became Aithon Ricerche International, much time have been spent in research of new intumescent systems and in the development of completely new products, and the results of the European tests were encouraging. We decided to focus on concrete and timber fire resistance, the fields where we are still investing more, and now the AITHON brand is present in a growing number of European countries.

Two Class leading product now are;

Aithon A90H Application

Given the importance and requirements for structural steel reports prior to any application of the Aithon A90H - Aithon Ricerche reserves the right to only permit it's certified and approved contractors to apply its concrete intumescent coating to establish absolute peace of mind in the application of the concrete fire protection coating to reduce the risk to both property and lives. In the UK, this fire stopping installer can be found here which is a leading passive fire protection contractor working across the UK.
