Everbond Styrobond ST is a specialist contact adhesive for bonding expanded polystyrene (EPS) foam to compatible sheet materials, including metal, fibre-cement, plywood and particleboard. It is designed for foam-laminating jobs where a conventional solvent contact adhesive could damage or dissolve the polystyrene.
Choose Styrobond ST when fabricating compatible EPS-backed panels or insulation assemblies. Its purpose is different from standard SP-230 Spray Contact and Brush Contact, which should not be assumed safe for expanded polystyrene.
Work on clean, dry, stable surfaces and carry out a sample bond before production. Apply an even coat with equipment suitable for the adhesive and the substrate, then follow the prescribed evaporation and assembly process. Apply uniform pressure to the joined surfaces to establish full contact, particularly at panel edges.
Do not substitute a generic solvent contact adhesive for an EPS-compatible grade. Avoid trapped solvent, uncontrolled temperatures and untested load-bearing panel assemblies. Compatibility testing remains important because foam grades, coatings and manufactured panel facings differ.
Will Styrobond ST melt polystyrene?
No. It uses solvents selected for bonding expanded polystyrene without attacking the foam.
Do I apply it to one surface or both?
Apply it to both mating surfaces and allow each film to dry before joining.
What temperature range can it be applied in?
The documented range is 10°C to 35°C, with extra condensation risk below 18°C in high humidity.
How much coverage should I expect?
About 1.5m² per litre across both surfaces by brush or roller, or up to 2.5m² per litre by spray.
