Résumé : |
In recent years, thin film intumescent coatings have become the preferred choice for the protection of structural steel. This is a result of their ability to provide a cost-effective passive fire protection solution while maintaining the aesthetic qualities of the steel, which is being demanded by more and more architects and engineers.
Over the years, multiple generations of solventborne resins have been developed that, when formulated into end-use coatings, have proven durable and effective in reactive fire protection. We have offered such solutions based on a unique manufacturing process, polymer composition, and morphology. Now, a new water-based resin technology, based on the same chemistry and expertise, has been developed to meet the fire-resistance requirements of best-in-class products.
This article describes the development of this technology, which allows formulators to achieve superior water resistance compared to current existing water-based products, when tested according to durability requirements of standards such as ETAG 018/EN 16623. |
