Thermocoat WI - Water-based Intumescent Paint System

A water-based intumescent paint system providing fire resistance to structural steel and cast iron that may be applied by brush, roller or airless spray.

The heat of a fire triggers a catalytic reaction, causing the expansion of an insulating char layer up to 50 times the paint thickness. This layer keeps the steel below its critical temperature, thus maintaining the structural integrity of the building.

Features and benefits:

• Minimum 30 minutes fire resistance subject to manufacturer's guidelines.
• Low-odour, water-based coating, making it user and environmentally friendly.
• Can be top coated with flame-retardant gloss, eggshell, water-based satin or water-based matt (BS 4800 & RAL colours).
• The range of topcoats are either water-based or 2010 compliant and safe to use in accordance with manufacturer’s instructions.
• Thermoguard issue a Certificate of Supply on request for each specified project for insurance, Fire and Building Control Authority and Client Records.

• Dry internal: Apply in accordance with Thermoguard film thickness schedule to achieve 30, 60, 90 minutes.
• Visible or occasional modest damp internal areas: Also apply one good coat of Thermoguard Flame Retardant Paint.
