What Temperature Does Intumescent Paint React

Intumescent paint reacts when its temperature attains or exceeds 120°C, and the process results in a soft charring effect at its surface (which insulates and reduces transmission of heat into the substrate) and the release of water vapour (which helps to cool the substrate).

Is intumescent paint fireproof?

Intumescent coatings, often referred to as intumescent paint, are used in buildings as a passive fire resistance measure. They can be applied to structural members as an aesthetically pleasing fireproofing product.

How long does intumescent paint take to dry?

Depending on the thickness of the coats applied and the air temperature and humidity, each coat will take approximately one to two hours to dry.
