Thanks to the combination of elemental and structural analyses!
Structural analysis by pyrolysis on a paint flake made it possible to identify epoxy, vinyl polyester, styrene-acrylic urethane matrices. On the other hand, no swelling agent, carbohydrate compound or flame retardant agent was observed.
Elemental analysis, meanwhile, confirmed the epoxy matrix of this paint due to the majority presence of carbon and oxygen. The absence of phosphorus, antimony and boron highlights the absence of phosphoric or boric acid, generally used in intumescent systems.
These analysis results make it possible to conclude on the nature of the paint and in particular on the fact that it was not a priori an intumescent paint.
Our client will therefore be able to renovate the building in order to incorporate an intumescent paint for better protection against potential fires.
