Product Description

Product Description

 

Product Name

Unsaturated Polyester Resin

 

Chemical Structure

Unsaturated polyester resin is a polymer material containing unsaturated double bonds. It is primarily synthesized by the polymerization reaction between polyols (such as ethylene glycol and propylene glycol) and dicarboxylic acids (such as phthalic acid and maleic anhydride), then mixed with reactive monomers (such as styrene) to form a prepolymer capable of cross-linking.

 

Physical Properties

• Appearance: Transparent or semi-transparent liquid.
• Viscosity: Approximately 200-1200 cps (varies by model).
• Density: Around 1.1-1.2 g/cm³.
• Gel Time: 10-60 minutes (adjustable based on specific needs).
• Curing Temperature: Room temperature curing, with an option for heat curing.
• Hardness: Post-cure hardness can reach 70-90 Shore D.

 

Technical Characteristics

1. High Strength
   Unsaturated polyester resin exhibits excellent mechanical strength and impact resistance after curing, suitable for applications requiring rigidity and strength.

2. Chemical Resistance
   This resin offers resistance to acids, bases, and solvents, ideal for anti-corrosion coatings, pipelines, and storage tanks in industrial environments.

3. Versatile Molding Capabilities
   It can be molded through various techniques such as hand lay-up, spraying, pultrusion, and compression molding, making it widely applicable in composite manufacturing.

4. Fast Curing
   With the addition of peroxide-type initiators, it can cure quickly at room temperature, making it suitable for efficient production and reducing energy costs associated with heat curing.

5. High Processability
   The resin is easy to mix and process, with options to add various additives and fillers to achieve specific properties such as toughness, reinforcement, and flame retardancy.

 

Applications

• Automotive Industry: Used for lightweight car body parts, bumpers, roofs, etc.
• Marine and Shipping: Suitable for small boat hulls, decks, bulkheads, and other structural components.
• Building Materials: Used in fiberglass panels, pipes, storage tanks, and waterproof coatings.
• Electronics and Electrical: Applied in electrical insulation parts, heat-resistant components, etc.
• Consumer Goods: Used for everyday plastic items, flowerpots, chairs, and tables.

 

Storage and Shelf Life

• Storage Temperature: Recommended to be stored in a cool, dry place below 25°C.
• Shelf Life: Up to 6 months if unopened. Beyond this period, the product should be tested before use.
• Precautions: Avoid direct sunlight and high temperatures to prevent unintended curing due to catalyst exposure.

 

Packaging

• Standard packaging is a 200 kg drum, with custom packaging available upon request.

 

Safety and Handling

1. Safe Handling: Wear protective gloves and goggles to prevent direct skin and eye contact.
2. Ventilation: Use in a well-ventilated area to avoid inhaling volatile styrene monomers.
3. Disposal: Dispose of waste according to local regulations to prevent environmental contamination.

 

Product Advantages

• High strength and durability, suitable for structural applications.
• Excellent corrosion resistance, ideal for harsh industrial environments.
• Compatibility with various molding techniques, providing flexibility in composite production.
• Quick room temperature curing, improving production efficiency and reducing energy consumption.
