IMPROVED RESIN SYSTEM FOR INTUMESCENT COATINGS
20230120483 · 2023-04-20 · ·

An innovative reactive resin system can be used for intumescent coating. Intumescent coatings are used in particular for fire protection of metallic components, such as girders in structural engineering. In a fire scenario, these coatings are reactively foamed and so form a fire-resistant insulating layer with low thermal conductivity around the metal girder, with the resultant insulation retarding premature failure of this component. The resin systems are prepared by an innovative process where the monomer fraction is polymerized only up to a maximum degree of 70%. The glass transition temperature of this polymeric component of the resultant composition is particularly low.
