Use Styrobond ST Spray Grade Polystyrene Foam Adhesive for: Bonding polystyrene foam to various materials like sheet metals, fibre cement, plywood, and particle board.
Styrobond ST Spray Grade Polystyrene Foam Adhesive is a specialized contact adhesive formulated for bonding polystyrene foam to a variety of substrates. Unlike conventional contact adhesives, Styrobond ST uses special solvents that won't damage polystyrene. Its low viscosity makes it ideal for spray application, ensuring efficient coverage and strong, durable bonds. This adhesive is perfect for applications requiring a reliable bond between polystyrene and materials such as sheet metal, fibre cement sheet, plywood, and particle board.
Key Features of Styrobond ST Spray Grade Polystyrene Foam Adhesive
- Polystyrene-Safe Formulation: Formulated with special solvents to prevent damage to polystyrene foam, ensuring a strong and lasting bond without degradation. For example, it can be used to bond polystyrene insulation to walls without concern for the adhesive dissolving the foam.
- Sprayable Application: Low viscosity allows for easy and efficient application with conventional spray equipment, saving time and ensuring even coverage. This is particularly beneficial for large surface areas, such as bonding polystyrene sheets in cool rooms.
- Strong and Durable Bond: Provides a high-strength bond on both porous and non-porous surfaces, ensuring long-term adhesion and reliability. This makes it ideal for applications where the bond must withstand stress, such as in packaging or construction.
- Versatile Bonding: Bonds polystyrene foam to a variety of materials including sheet metals, fibre cement sheet, plywood, and particle board, making it suitable for diverse applications. For instance, it can be used to adhere polystyrene to plywood in the manufacture of signs.
Technical Overview
Styrobond ST Spray Grade Polystyrene Foam Adhesive is a rubber solvent adhesive designed for spray application. Its key technical property is its formulation with solvents that are safe for polystyrene foam. The low viscosity ensures it can be applied evenly and efficiently with spray equipment, providing a uniform bond line. This is critical for achieving maximum adhesion and preventing weak spots.
Chemical Properties: Rubber solvent based, this adhesive is designed to create a strong bond through solvent evaporation. The specific solvent blend is crucial for its compatibility with polystyrene, preventing the foam from being dissolved or degraded.
Application Temperature Range: 10°C to 35°C (50°F to 95°F). This temperature range is critical for proper application and bond formation. Applying the adhesive outside this range can lead to poor adhesion or improper curing. For example, applying it on a very cold day may prevent the solvents from evaporating properly, resulting in a weak bond.
Application Information
- Required Tools: Conventional spray equipment (spray gun, compressor), wooden block and mallet, hand roller, or mechanical nip-roller.
- Trade-Specific Tips: Ensure surfaces are clean, dry, and free of contaminants. For metals, wipe with a solvent for maximum bond strength. Apply a liberal, even coat to both surfaces. Allow the adhesive to dry completely before bringing surfaces together. Use adequate pressure during bonding.

Common Issues and Solutions:
- Weak bond: Ensure proper surface preparation, even adhesive application, sufficient drying time, and adequate pressure.
- Uneven spray pattern: Adjust spray equipment for a consistent and even spray.
- Lifting laminates: Use G clamps or sash clamps to maintain pressure during the bonding period.
Storage and Shelf Life
- Storage Requirements: Store in a cool, dry place between 10°C and 35°C (50°F and 95°F). Keep containers tightly closed when not in use.
- Shelf Life Information: 12 months from the date of production.
- Temperature Considerations: Avoid storing the adhesive outside the recommended temperature range, as it can affect its performance and shelf life.
Frequently Asked Questions About Styrobond ST Spray Grade Polystyrene Foam Adhesive
Q: How do I prepare surfaces before applying Styrobond ST?
