Product Introduction

Ultra-fine inorganic fiber spray-specific adhesive is a water-based, environmentally friendly specialty adhesive specially developed for ultra-fine inorganic fiber spray systems. Its primary function is to firmly bond ultra-fine inorganic fiber wool (diameter ≤ 5 μm) to the surfaces of various building substrates, forming a continuous, airtight, and stable integrated coating that provides thermal insulation, fire protection, and sound absorption. It serves as the core supporting material for inorganic fiber spray technology.

Core Performance Features

1. Exceptional Adhesion Performance

It exhibits exceptionally strong adhesion to a wide range of substrates, including concrete, steel structures, masonry, wood, and metals, and can tightly interweave ultra-fine inorganic fibers into a three-dimensional network structure, ensuring that the coating does not flake, crack, or chalk.

It is suitable for challenging substrates such as irregularly shaped, complex, and densely packed piping systems, offering seamless installation with no thermal bridges and excellent structural integrity.

2. Environmentally friendly, safe, and non-toxic

Water-based formulation, free of formaldehyde, benzene-series compounds, heavy metals, and other harmful substances; during application and use, it exhibits no volatile emissions, no off-gassing, and no radioactivity.

Antibacterial and mildew-resistant, with excellent resistance to acid and alkali corrosion; it does not harbor mold even after prolonged use and complies with national environmental protection and indoor air quality standards.

3. Fireproof and Flame-retardant (Class A Matching)

It is non-combustible, does not support combustion, and produces no smoke; when combined with ultra-fine inorganic fibers, it can achieve Class A1 non-combustible fire protection, with a fire-resistance rating of up to 5 hours or more.

No toxic fumes are released at high temperatures, meeting stringent fire safety codes for buildings, garages, factories, and other applications.

4. Weather-resistant and durable stability

It is water-resistant, moisture-resistant, freeze-thaw resistant, and aging-resistant, capable of withstanding harsh conditions such as temperature fluctuations, ultraviolet radiation, and high humidity, with a service life exceeding 20 years.

Resistant to wind erosion and vibration, the coating maintains its integrity and functionality over the long term.

5. Convenient and Efficient Construction

Single-component, ready-to-use; simply dilute with water according to the specified ratio (typically 1:10 to 1:13), stir thoroughly, and apply directly.

It cures rapidly, allows for mechanized continuous construction, significantly boosts efficiency, and shortens the project schedule.

It exhibits excellent compatibility with ultra-fine inorganic fibers, resulting in uniform fiber distribution and a smooth surface after spraying.

6. Collaborative Enhancement of System Functions

When combined with fibers, it enhances thermal insulation (with a thermal conductivity as low as 0.037 W/(m·K)), sound absorption and noise reduction (approximately 29 dB of noise reduction at a thickness of 3 cm), and vibration damping performance.

Scope of Application

1. Building Thermal Insulation and Fire Protection

Underground parking garage, basement ceiling, stairwell, interior surface of curtain wall, equipment room, and elevator shaft.

Fire protection for high-rise steel structures, industrial plants, warehouses, storage tanks, tunnels, and subway systems.

2. Sound Absorption and Noise Reduction Engineering

Gymnasiums, cinemas and theaters, concert halls, libraries, conference rooms, schools, and hospitals.

Acoustic treatment for bars, KTVs, restaurants, airport lounges, industrial facilities, and rail transit systems.

3. Special and Complex Scenarios

Traditional materials are difficult to work with in areas such as irregular roof surfaces, arched structures, zones with dense piping networks, and areas with a high density of suspended components.

Areas with high humidity, condensation, and a risk of condensation (swimming pools, underground spaces).
