The Indoor Expansion Type Steel Structure Fireproof Coating (Solvent Type) is a high-performance intumescent fire protection solution specially formulated for indoor steel structures.
Product Introduction
The Indoor Expansion Type Steel Structure Fireproof Coating (Solvent Type) is a high-performance intumescent fire protection solution specially formulated for indoor steel structures. When exposed to extreme heat or flames, the coating undergoes an intumescent reaction, expanding into a thick, dense char layer that effectively insulates the steel substrate. This protective barrier prolongs the structural stability of steel during fire exposure, providing critical evacuation and rescue time while minimizing fire-related damage. The solvent-based formulation ensures excellent adhesion, fast curing, and reliable durability, making it an ideal choice for demanding construction projects where long-term safety is essential.
Product Details
This solvent-type intumescent coating is manufactured with advanced resins, fire-retardant additives, and stabilizers to guarantee outstanding fire resistance and service life. It is available in ready-to-apply form, suitable for spray, brush, or roller application. The coating produces a smooth, uniform film that can be overcoated with decorative finishes to meet architectural design requirements. Depending on project specifications, the dry film thickness can be adjusted to achieve 30, 60, 90, or 120 minutes of fire protection.
Product Advantages
Excellent Fire Resistance: Provides up to 2–3 hours of certified fire protection.
Fast Curing: Solvent-based system cures more quickly than water-based alternatives, especially in low-temperature or high-humidity conditions.
Superior Adhesion: Strong bonding to primers and steel surfaces, resistant to peeling, cracking, or delamination.
Durable Performance: Outstanding resistance to moisture, indoor atmosphere, and mechanical impact.
Smooth Decorative Finish: Thin-film application provides an elegant surface, ideal for visible steel structures in modern architecture.
Flexible Application: Compatible with a variety of primers and topcoats for enhanced corrosion resistance and decorative effects.
Product Features
Intumescent expansion ratio of 20–30 times, forming a stable carbonized protective layer.
Can be applied in a wide range of indoor construction environments.
Resistant to general humidity and indoor atmospheric conditions.
Long service life with minimal maintenance requirements.
Available in white or neutral tones for easy top-coating.
Product Applications
This solvent-type coating is widely applied in various steel structure projects, including:
Commercial complexes, shopping malls, and office towers.
Transportation hubs such as airports, train stations, and exhibition centers.
Public facilities including theaters, stadiums, and convention halls.
Industrial plants, warehouses, and workshops.
Residential high-rise buildings and underground facilities.

FAQ
Q1: What is the shelf life of the product?
A1: The shelf life is 12 months in unopened containers, stored in a cool, dry, and ventilated environment.
Q2: Can it be used directly on bare steel?
A2: It is recommended to apply a corrosion-resistant primer first for improved adhesion and durability.
Q3: Is this product suitable for outdoor use?
A3: This coating is designed for indoor applications. For outdoor projects, a weather-resistant system should be selected.
Q4: How do I calculate the required coating thickness?
A4: The thickness depends on the fire-resistance rating (e.g., 1–2 mm for 30–60 minutes, 2–3 mm for 90–120 minutes). Technical datasheets and calculation guides are provided by our engineering team.
Q5: What are the main differences between solvent-based and water-based coatings?
A5: Solvent-based coatings cure faster, have stronger adhesion, and perform better in challenging environments, while water-based coatings are more environmentally friendly and odorless. The choice depends on project requirements.
Q6: Is it safe for construction workers?
A6: Yes, when proper ventilation and protective equipment (gloves, masks) are used during application. The coating is formulated to minimize harmful emissions, but safety protocols should always be followed.
