Astro ISS Intumescent Paint insulates structural steel and cast iron steel during a fire, keeping them below the critical (collapse) temperature.

Astro ITC and Astro IFV Intumescent Coatings control flame spread and fire propagation on wood.

Fire retardant and flame retardant paints assist in the control of fire hazards from combustible materials, such as wood, by releasing a flame extinguishing gas when exposed to the high temperature of a fire.

Fire proof paints can be used on new or old surfaces. Improved fire resistance can be imparted to accumulations of flammable paint (due to repeated overpainting) on old plaster or brickwork by applying an intumescent coating and a flame retardant paint decorative top-coat.

For certification and compliance with regulations we will supply a FREE of charge Certificate of Supply with each order or project.
