Looking for the best glue for thermocol? Choosing the right thermocol glue is important for achieving strong, durable bonding without damaging EPS foam sheets. Whether you are bonding thermocol to wood, metal, plastic, concrete or insulation panels, the right adhesive improves strength, productivity and long-term performance.
What Is a Thermocol Adhesive?
Thermocol adhesive is a special glue used to bond thermocol (EPS – Expanded Polystyrene) to materials like wood, metal, plastic, and concrete. It is designed to create strong bonds without melting or damaging thermocol, which is sensitive to harsh chemicals.
Thermocol is widely used in packaging, insulation, construction, and decorative work. Because it is lightweight and porous, it needs a reliable EPS adhesive that provides strong and long-lasting bonding.
Modern thermocol adhesives offer high strength, fast setting, and good moisture resistance, making them suitable for industrial and commercial applications.
What is thermocol, EPS?
Thermocol (scientifically known as EPS or Expanded Polystyrene) is a lightweight, rigid, closed-cell foam plastic material. It is made by expanding polystyrene beads with steam. Because it is composed of roughly 98% trapped air, it is incredibly light while offering excellent shock absorption and thermal insulation.
Why solvent based glues can damage thermocol?

How to Apply Thermocol Adhesive (Step-by-Step)
Applying Supex 7150 correctly ensures strong bonding and long-lasting performance. Follow these simple steps for best results.
Step 1: Clean the Surfaces
Make sure the thermocol and bonding surface are clean, dry, and free from dust, oil, or moisture. Clean surfaces help the Supex 7150 bond more effectively.
Step 2: Apply the Adhesive Evenly
Apply a thin and uniform layer of thermocol glue on one surface using a brush, roller, or applicator. Avoid applying too much adhesive, as excess glue can reduce bonding strength.
Step 3: Join the Surfaces
Carefully place the thermocol sheet onto the surface and align it properly. Press the surfaces together firmly to ensure full contact.
Step 4: Apply Pressure
Hold or press the bonded surfaces for a few minutes. In industrial applications, clamps or weights can be used to maintain pressure.
Step 5: Allow Proper Curing Time
Let the glue adhesive cure for 10-20 minutes depending on weather. Avoid moving the bonded parts until the adhesive has fully set.
Why Choose Supex Thermocol Adhesive?
• Single-component PUR adhesive
• Zero VOC solvent-free formula
• Fast curing time (15–30 minutes)
• High strength bonding
