At a Glance: Key Applications
Use Styrobond ST for: Bonding EPS foam to fibre cement, plywood, particleboard, and metals—ideal for insulation, cladding, and lightweight panel assembly.
Styrobond ST: A Technical Overview
Styrobond ST is a purpose-formulated spray-grade adhesive engineered to bond expanded polystyrene (EPS) foam to various substrates without causing melt-back or degradation. Unlike traditional solvent-based adhesives, it uses a polystyrene-safe solvent system. With its fast tack time and reliable holding power, it's perfect for on-site and prefabrication settings where high coverage and speed are essential.
Core Features & Specifications
- Spray-grade consistency allows rapid and even application with conventional spray equipment.
- Safe for direct application to polystyrene—no foam degradation.
- Cures via solvent evaporation, forming high-strength, flexible bonds.
- Clear or green tint options for visual control during application.
- High bond coverage up to 2.5 m² per litre with spray equipment.
The Styrobond ST Advantage
- Eliminates risk of foam damage when bonding polystyrene panels.
- Saves labour time through spray efficiency and fast drying.
- Minimises overspray issues with controlled spray patterning.
- Provides durable adhesion even under variable site conditions.
Coverage Rate & Yield
Spray application provides up to 2.5 m² per litre of bonded surface (both sides). For brush or roller, expect approx. 1.5 m² per litre. Coverage may vary with substrate porosity and environmental conditions.
Application & Service Temperature Range
Apply between 10°C and 35°C for optimal performance. Avoid conditions below 18°C and high humidity, as they may interfere with solvent evaporation and bond formation.
Chemical Profile & Substrate Compatibility
Styrobond ST is a rubber-solvent adhesive using polystyrene-safe solvents like hexane. It adheres well to porous and non-porous surfaces and resists shrinkage, curling, and lifting when pressure is properly applied.
Storage & Shelf Life Considerations
Store in cool, dry environments between 10°C and 35°C. Shelf life is 12 months in unopened containers.
Frequently Asked Questions About Styrobond ST
Q: Will Styrobond ST damage polystyrene foam?
A: No. Styrobond ST is formulated with polystyrene-safe solvents, making it ideal for EPS foam without causing melting or degradation, unlike traditional contact adhesives.
Q: What type of spray equipment is required?
A: Use conventional spray guns with a sustained pressure of 450–850 KPa. Ensure even spray patterns to avoid weak bonding areas.
Q: Can this adhesive be used in cold weather?
A: Avoid use below 18°C, especially in high humidity. Cold, damp conditions can result in moisture condensation and weakened bonds.
Q: How should I clean tools after application?
A: While wet, clean with hexane or xylene. Once cured, mechanical removal is required. Avoid letting residue dry on spray guns.
Applications & Benefits
| Application / Use Case | Key Benefit | Primary Trades |
|---|---|---|
| EPS Panel to Fibre Cement | No foam degradation, high bond strength | Builders, Cladding Installers |
| Polystyrene to Plywood | Quick grab and even coverage via spray | Insulation Contractors |
| Metal Sheet to Foam | Solvent-safe and strong under pressure | HVAC Installers, Refrigeration |
Applying Styrobond ST: Protocols & Best Practices
General Application Steps:- Preparation: Ensure all surfaces are dry and clean. Remove grease or dust, especially on metals. Use solvent for degreasing metals.
- Application: Apply a uniform coat to both surfaces with a spray gun at 20–30 cm distance. Let dry until tack-free.
- Joining: Bring surfaces together and press firmly using a hand roller, rubber mallet, or nip roller with ≥700 kg/m² pressure.
- Drying Time: Drying depends on ambient conditions. Ensure complete solvent evaporation before assembly, especially for non-porous surfaces.
For Insulation Installers: Wall Panel Bonding
The Engineering Challenge: Avoiding foam damage during large-scale EPS panel bonding on site.
The System-Based Solution with Styrobond ST: Spray-grade application provides quick, even coverage without melting foam, reducing material failure.
Best Practice Note: Always ensure solvents are fully evaporated before joining to prevent bond failure.
Limitations & Safety
Product limitations and safety information
Limitations:
- Not suitable for temperatures below 10°C or high-humidity environments.
- Ensure surfaces are completely dry—trapped solvent weakens the bond.
- Not for continuous submersion or structural applications.
Safety & Handling:
- PPE: Gloves, goggles, and solvent-resistant clothing recommended.
- Ventilation: Use in a well-ventilated area to avoid fume inhalation.
- Handling: Store sealed in cool, dry conditions. Avoid heat or flame.
- First Aid: In case of contact with skin or eyes, rinse thoroughly. Seek medical attention if irritation persists.
