Aofeng Group Launches Single-Component Sprayable Polyurethane Foam Sealant to Boost Efficiency in Professional Construction

Recently, Aofeng Group officially unveiled a new product: a single-component sprayable polyurethane foam sealant. Designed for use with a specialized spray gun, this product is ideal for large-scale, high-efficiency joint filling and sealing operations. Primarily targeting professional sectors—such as general construction, waterproofing and thermal insulation, and industrial manufacturing—it meets the rigorous demands of contractors regarding both construction speed and sealing quality.

**Spray-Gun Application: A Major Boost in Efficiency**

Unlike traditional gun-applied or tube-dispensed foam sealants, Aofeng’s sprayable sealant requires the use of a dedicated spray gun and compressed air. This spray application method enables continuous, uniform coverage over large areas, significantly enhancing construction efficiency. It is particularly well-suited for extensive operations such as roof insulation, wall cavity filling, and pipe sealing.

The product's foam output can be flexibly adjusted via the spray gun, allowing construction personnel to control the flow in real-time based on joint width, filling depth, and working conditions. This ensures an effective seal while simultaneously minimizing material waste.

**Tailored to the Needs of Professionals**

**Construction Contractors:** Used for filling door and window openings, sealing exterior wall insulation layers, repairing roof waterproofing membranes, and more. The spray application method drastically reduces the time required for individual tasks, thereby accelerating overall project progress.

**Waterproofing & Insulation Teams:** Upon curing, the product forms a dense, elastic elastomer that exhibits excellent waterproofing, soundproofing, and thermal insulation properties, meeting dual standards for both building energy efficiency and waterproofing integrity.

**Industrial Manufacturing & Equipment Installation:** Suitable for various industrial applications, including sealing equipment openings, sealing pipe penetrations, and filling voids within enclosures. It features strong adhesion and excellent weather resistance, ensuring long-term durability and reliable performance. Core Product Advantages

**Continuous & Uniform Spraying:** When paired with a spray gun and air source, it delivers a stable adhesive flow, covers a large surface area, and ensures a seamless, uninterrupted application.
**Strong Bonding Strength:** Exhibits excellent adhesion to a wide variety of substrates, including concrete, metal, wood, glass, and ceramics.

**High Expansion Ratio:** A single-component, moisture-curing formula that produces a fine, dense foam capable of providing full and complete filling.

**Multi-functional:** Offers a combination of waterproofing, sound insulation, thermal insulation, electrical insulation, and vibration-damping properties.

**Flexible Application:** Once cured, the foam can be freely cut, sanded, and painted to suit specific project requirements.

**Weather-Resistant & Durable:** Retains its elasticity within a temperature range of -10°C to 80°C, ensuring a long service life.

**Safe & Eco-Friendly:** Contains no CFCs and remains safe and reliable under standard construction conditions.
