Primers & Topcoats

An intumescent system generally includes a primer, intended to improve adhesion to substrate and in the case of steel substrates to provide protection from corrosion.
In a number of cases, a topcoat is also needed to improve durability providing protection from moisture and the environment, or specified for easthetic purposes and giving a colour.
According to European standards (ETAG 018, EN 16623) these primers and topcoats should be evaluated for their compatibility in the performance of the whole system.
Our product portofolio includes suitable primers and topcoats that have been tested and approved in combination with our intumescent coatings.
