【NEW】DC7120 Intumescent Coating

Model：DC7120

Product description

NEW PRODUCTS ARRIVAL!

Product Introduction

Product Description
DC7120 is a single component water based intumescent coating specially designed to increase the fire resistance of structural steel.
Upon exposure to flame or heat, it immediately foams and intumesces to form a thermal barrier layer that provides a very effective
insulation to protect the steel sections from fire and heat.

Uses
Used as interior environments paint for structural steel to provide up to 120 minutes of fire rating on I/H section beams and columns.

Features

Certifre Listed with Warringtonfire in accordance with BS476 Part 21
Fire Rating up to 2 hours
Water borne, environmentally friendly
Smooth and architecturally pleasing finish
Very low odour
Fast drying and rapid recoating properties
Excellent durability

Application guide

Surface Preparation

All steel surfaces should be free from any contaminant and should be treated by abrasive blast cleaning before priming.
A DC7120 compatible primer is required to apply on steel section at 50~75 μm DFT.

Application Method

DC7120 can be applied onto steelwork not below 5℃ (41℉) and relative humidity not above 80%. Steel surface should be at least 3℃ above the dew point.
DC7120 is best applied using airless spray equipment. Thinning is not normally required.
Up to 0.7mm (WFT) can be applied in a single coat. Dry for 6~12 hours after application of each coat to recoat.
Final specified DFT may be taken using an electronic electromagnetic type gauge. Refer to AWCI Technical Manual 12-B.

Topcoat Application

A compatible topcoat can be applied to protect DC7120. Make sure DC7120 is fully cured before applying topcoats.
(Please refer to Product Data Sheet as INCA provides for more details.)
