Adhesive for Expanded Polystyrene Quantec KST-750 Thermostyro-Fix, cartridge 750 ml

Quantec KST-750 Thermostyro-Fix is an adhesive formulated for bonding expanded polystyrene (EPS) insulation panels. Supplied in a 750 ml cartridge, this product is intended for façade and interior applications where reliable adhesion to common building substrates is required. The formulation is compatible with the use of standard mechanical fixings and supports both renovation and new-build insulation projects.

Advantages

The adhesive provides consistent tack and curing behavior across typical site temperatures, allowing controlled application from a cartridge gun. Its composition is designed to create a durable bond between EPS panels and substrates such as masonry, concrete, and render. The cartridge format enables accurate dispensing, reduces material waste and is suitable for spot or bead application patterns used in thermal insulation systems.

Suitable for

• Bonding expanded polystyrene (EPS) insulation panels to façades
• Adhering EPS on interior walls and partition systems
• Use with mechanical fixings in external thermal insulation composite systems (ETICS)
• Installation during renovation and new construction insulation works

Key specifications

• Form: cartridge for caulking gun, 750 ml volume
• Primary use: adhesive for expanded polystyrene (EPS) insulation panels
• Application methods: manual cartridge gun; suitable for spot or continuous bead application
• Compatible substrates: masonry, concrete, cement render, and similar common building substrates
• Working conditions: suitable for typical site temperatures; follow manufacturer temperature guidance for best results

How to use

Prepare substrate surfaces by ensuring they are clean, dry and free from dust, loose particles, grease or other contaminants that could impair adhesion. Load the 750 ml cartridge into a compatible caulking gun. For standard EPS panel installation, apply adhesive in spots or continuous beads according to panel size and project requirements, maintaining even pressure for consistent extrusion. Press the insulation panel firmly onto the substrate and align as needed. Where specified, supplement adhesive with standard mechanical fixings to meet wind-load and regulatory requirements. Allow the adhesive to develop initial tack before any further handling; final curing time depends on ambient conditions.

Usage recommendations

Store cartridges upright in a cool, dry place away from direct sunlight and freezing temperatures. Use personal protective equipment such as gloves and eye protection when handling and applying the adhesive. Follow local building codes and project specifications for the number and placement of mechanical fixings in thermal insulation systems.
