    Interior Structural Steel Thick Film Fire Protection Coatings 2 Hour Rating Building / Hotel

    120Min Non - Halogen Interior Structural Steel Thick Film Paint Liquid Intumescent Fire Protection Coating
    Modern design practice has increasingly incorporated architecturally exposed structural steel, or AESS. Originally used by structural engineers as a highly elaborate exoskeleton, AESS has evolved into an outlet for both engineers and architects to integrate components of their work into the visibly finished structure. If these exposed design elements are also part of the primary structural components of the building, the integrity of the structural steel must be protected with an intumescent fire protection coating.
    Intumescent paints for steel, structural steel and cast iron at Zhuoan Paints are available with 60, 90 ,120,180-minute fire protection. The intumescent coating are available for interior use , most of our fire-resistant paints are easy to apply by brush, roller or spray, with no specialist skills required and fire certificate issued on completion.
    The product is applied directly to the contour of primed I and H section columns, angles, channels, beams and hollow sections to provide fire protection for up to 180 minutes. In a fire, a chemical reaction takes place causing the fire resistant paint to expand and form an insulating layer which slows the temperature of the steel rising to a critical level. Steel starts to lose its load bearing capacity at a temperature of around 550°C during a fire. Zhuoan® intumescent paint is designed to protect the buildings main structure in the event of fire.

    Thick film intumescent coating systems generally have three components, a primer, a basecoat (the part which reacts in the fire) and a sealer coat. The basecoat usually comprises the following ingredients:

    • A catalyst which decomposes to produce a mineral acid such as phosphoric acid.
    • A carbonific such as starch which combines with the mineral acid to form a carbonaceous char.
    • A binder or resin which softens at a predetermined temperature.
    • A spumific agent which decomposes together with the melting of the binder, to liberate large volumes of non-flammable gases. These gases include carbon dioxide, ammonia and water vapour. The production of these gases causes the carbonaceous char to swell or foam and expand to provide an insulating layer many times the original coating thickness.


    Excellent fireproof performance
    Easy application and good decoration effect
    Stable physical and chemical properties 
    Good adhesion force, hard to produce peeling


    Surface PreparationThe substrate surface must be clean,dry and free from contamination, such as dust,oil stain,water stain,etc.
    MixingFix the paint with water by ratio 1:1, and stir well.
    Construction Method
    • To clean surface of the steel structure ,the substrate surface should be free of dust, rust,oil and other impurity
    • The first brushing paint thickness cant surpass 5mm, and dont execute the second layer brushing until the first layer become dry. The paint thickness could be adjustable as per the requirement.
    • The coating thickness should be uniform, the surface should be flat.
    • Construction environment temperature should be above 5℃, relative humidity is less than 85%.
    Brush ToolWool brush or nylon brush
    Construction ConditionDont execute construction when temprature is under 5℃ or air humidity is above 85%. And keep good ventilation
    NotesMaterials is not allowed to remain in hoses, guns or spray equipment. All unused materials should be sealed and, clean all tools timely after using with clean water. It is good to periodically flush the spray tools during the daily work.All surplus materials&empty containers should be properly disposed.

    Buying Guides

    How/Where to Use

    What Are The Most Common Applications For Zhuoan’s Fireproof Coating?

    The most common applications for Zhuoan’s Fireproof Coating are in the building industry. Historic architecture,wood cottage, furniture,lumber, OSB, polywood, wood fire resistant coating top the list. Hotel, hospital, theater, school ,airport, mall, factory are also a common usage with steel fire resistant coating.

    Can Zhuoan’s Fireproof Coating Be Applied Over Existing Rust And Corrosion?

    With wood Fireproof Coating,the substrate surface must be clean,dry and free from contamination, such as dust,oil stain,water stain,etc.With steel Fireproof Coating, only a NACE 3 / SSPC-SP 6 commercial blast cleaning is typically necessary.

    Application and Training

    What Does The Preparation Process Entail?

    Only a NACE 3 / SSPC-SP 6 commercial blast cleaning is typically necessary. There is no need to blast to NACE 1 or 2 since slight oxidation on the surface allows for the best chemical reaction.

    Can The Speed Of Reaction Be Slowed Down To Increase Working Time Before It Is Cured?

    There are various ways to decrease reaction time, but they are specific to the material being coated and environmental factors. We will advise you on this during the consultation.

    What Thickness Is Recommended?

    For wood Fireproof Coating,11.81mils; for steel Fireproof Coating, 118.11~1968.5mils, specific to the material being coated and fire resistant standard.

    Do I Need Special Equipment In Order To Apply Zhuoan’s Fireproof Coatings?

    Zhuoan’s fireproof coating applied using a plural (2K) spray gun or brush or roller. For spray model, the coating uses specific ratio, and sprays on using standard plural spray equipment that mixes at the nozzle of the spray gun. The process requires no heating equipment or other apparatus besides the plural spray gun.

    What Does The Certification Process Entail?

    Training is at our facility or yours. We teach you how to use it, the application process, and how to recognize proper effect. Experienced painters generally pick up the technique and understand the minor differences in a few minutes. We recommend two days of training to allow ample time to cover maintenance of the equipment, trouble shooting, and to understand the technology.
