Industrial Shotblast & Spraying Ltd

Protective coatings for steel can have a number of functions, one being fire protection. Intumescent coatings have been developed to protect structural steel in a fire situation.

The components in intumescent paint react in the intense heat of a fire to swell many times the initial thickness applied producing a carboneous char. This layer of char insulates the steel limiting its temperature rise.

When steel reaches 400°C it starts losing its strength and the rate increases the hotter the steel gets.  Intumescent paints have been developed to provide up to 120 minutes fire protection for a building to allow evacuation of people and thus potentially saving many lives.

Using a tightened speed from 60:1 ratio airless spray gun, ISS is capable of spraying fire proofing paints to a gloss finish with a top seal coat to your colour specification.

Providing intumescent to FB30, FB60, FB90 and FB120 standards, ISS is one of the few licensed FB120 intumescent operations in the UK. This superior quality and range of intumescent services now includes on site intumescent application through an expanded service operating as Industrial Site Painting Services.
