Intumescent Paint

Steel and Metal Coatings

Often called fire retardants, or mistakenly called "fireproof" paints, intumescent paints refer to that class of specially designed paints which swell and form a protective "char" as a result of extreme heat exposure.

Advantages of Intumescent Coatings

The advantages of this char are that it is a poor conductor of heat, meaning it will protect the structural steel it encases for an increased period of time.

An intumescent is comprised of three specific components:

  1. Carbon Supplier: Polyols as starch or pentaerythritol
  2. Acid Source: Ammonium polyphosphate
  3. Expanding Agent: Melamine

For the last 9 years Nullifire Australia has specialised in the supply of waterborne, halogen free and low VOC (Volatile Organic Compounds) intumescents suitable both for use on large structural steel sections and smaller aesthetic metal framework. Our thin film intumescents can applied in confined areas and around other trades with no impact and are available in 30, 60, 90 and 120 minute specifications.
