PeiYang Polyurethane Adhesives PY7230 is a two-component polyurethane adhesive formulated for industrial bonding where flexibility, adhesion, durability, and flame-retardant performance are important. Supplied as a gray paste after mixing, PY7230 is designed to bond different types of substrates and maintain its integrity under demanding operating conditions.

With a 1:1 mixing ratio, approximately 120 mPa·s mixed viscosity at 25°C, and a working temperature range of -40°C to 120°C, PY7230 is suitable for controlled dispensing and assembly processes. The cured adhesive provides excellent toughness and aging resistance, while its flame-retardant performance meets V-0 requirements.

Key Characteristics of PY7230 Polyurethane Adhesives

Designed for Multi-Material Bonding

PY7230 is formulated for use with various substrates, making it suitable for assemblies where different materials need to be bonded together.

Its bonding performance can be considered for combinations involving aluminum, PET films, plastics, and composite materials. This multi-substrate capability provides manufacturers with greater flexibility when developing assemblies containing different material types.

Toughness After Curing

The cured adhesive maintains good toughness rather than becoming excessively rigid. This characteristic helps the bonded joint accommodate mechanical stress, vibration, and movement caused by temperature changes.

For industrial assemblies exposed to repeated mechanical or environmental stress, this flexibility can help reduce the possibility of adhesive cracking.

Aging Resistance

Long-term adhesive performance is an important consideration for industrial products. PY7230 is designed with aging resistance to help maintain the integrity of bonded components over extended service periods.

This characteristic is particularly relevant for assemblies that may experience repeated temperature changes, environmental exposure, or continuous mechanical vibration.

Flame-Retardant Performance

Safety requirements can be critical when adhesives are used in industrial and electronic assemblies. PY7230 meets V-0 flame-retardancy requirements, providing an additional material option for applications where flame performance is part of the product specification.

Customers should evaluate the complete assembly and applicable certification requirements when selecting an adhesive for a specific application.

Controlled Gray Paste Consistency

After the two components are combined, PY7230 forms a gray paste with a mixed viscosity of approximately 120 mPa·s at 25°C.

The 1:1 volume ratio simplifies component proportioning and supports consistent dispensing when appropriate equipment is used.

Typical Industrial Uses

The combination of multi-substrate adhesion, toughness, aging resistance, and flame-retardant performance allows Polyurethane Adhesives PY7230 to be considered for a range of industrial bonding requirements.

Electronics and Component Assembly

PY7230 can be used for suitable bonding and encapsulation processes involving electronic components and housings. Its flexibility and flame-retardant characteristics can be relevant to assemblies where both mechanical and safety requirements need to be considered.

Automotive Components

Automotive interiors and selected structural or semi-structural components may require adhesives capable of handling vibration and temperature variation.

PY7230 provides a flexible bonding option for appropriate metal, plastic, film, and composite assemblies.

Optical and Display Modules

The adhesive can be considered for suitable optical and display-related assembly processes where different substrates need to be joined.

For sensitive components, manufacturers should conduct compatibility and process testing before mass production.

Metal-to-Plastic Bonding

Many industrial products combine metal and polymer components. Differences in thermal expansion between these materials can place stress on the adhesive joint.

The toughness and flexibility of PY7230 make it suitable for evaluating such multi-material bonding applications.

Equipment and Housing Assembly

Industrial equipment housings and enclosures may encounter vibration, humidity, and temperature fluctuations during operation. PY7230 can provide a bonding and sealing option for compatible assemblies where long-term joint stability is required.

Recommended Application Process

Correct surface preparation and controlled mixing are important for achieving consistent adhesive performance.

1. Prepare the Bonding Surfaces

Before application, surfaces should be clean, dry, and free from dust, grease, oil, and other contaminants. Depending on the substrate, additional surface preparation may be required.

2. Mix the Two Components

PY7230 uses a 1:1 volume mixing ratio. Components A and B should be combined thoroughly until a consistent gray paste is obtained.

Suitable dispensing equipment can help maintain the required component ratio and improve application consistency.

3. Apply the Adhesive

Apply an appropriate amount of mixed adhesive to the designated bonding area. Uniform distribution helps establish consistent contact between the substrates.

The exact adhesive quantity should be determined according to the joint design and application requirements.

4. Assemble the Components

Bring the substrates together within the applicable working period and maintain the required positioning during curing.

Curing behavior can vary with temperature, substrate, adhesive thickness, and other process conditions, so production users should validate the complete bonding process before commercialization.

Storage and Handling Requirements

Proper storage helps maintain the expected quality of the adhesive.

PY7230 should be kept in a sealed, dry, and light-protected location at 8–25°C. Under these specified storage conditions, the stated shelf life is 6–9 months.

For production applications, users should also follow the manufacturer's handling recommendations and conduct appropriate testing when introducing the adhesive into a new material combination or manufacturing process.
