【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
    1. All steel surfaces should be free from any contaminant and should be treated by abrasive blast cleaning before priming.
    2. A DC7120 compatible primer is required to apply on steel section at 50~75 μm DFT.
    • Application Method
    1. 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.
    2. DC7120 is best applied using airless spray equipment.  Thinning is not normally required.
    3. Up to 0.7mm (WFT) can be applied in a single coat.  Dry for 6~12 hours after application of each coat to recoat.
    4. 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.
