TECHNOMELT^®: Hotmelt adhesives for roof tile spacers

Our roof tile spacer solutions offer safe and efficient tile transportation.
Thanks to the superior glue film hardness, high thermal resistance, and excellent abrasion resistance, our TECHNOMELT^® portfolio ensures optimal separation between tiles, preventing damage such as chipping or scratching during handling, storage, and transit.

Our solutions are engineered for fast application and short setting time to ensure packaging process efficiency that delivers protection for clay and concrete tiles — and supports a wide range of application and stacking configurations.

Roof tile manufacturers face increasing pressure to deliver products in pristine condition while optimizing packaging speed and reducing material waste.

Tiles, whether clay or concrete, are highly durable in their installed form, but surprisingly vulnerable during transport. Effective tile transport solutions are critical, since even minor impacts or friction during palletization can lead to:

• Chipping at corners or edges
• Scratching of glazed or painted surfaces
• Cracks caused by uneven load distribution
• Aesthetic defects that reduce saleability

Traditional separation methods like cardboard sheets, foam layers, or mechanical spacers can increase material costs, slow down packaging lines, and generate significant waste.

This is where TECHNOMELT^® Hotmelt adhesives for roof tile spacers provide a clean, efficient, and sustainable alternative that reduces damage, cuts waste, and keeps your packaging line running at full speed.

TECHNOMELT^® solutions from Henkel set the benchmark for hotmelt adhesives in industrial applications — combining innovative polymer chemistry with decades of packaging and construction experience.

For roof tile applications, TECHNOMELT^® adhesives are specifically engineered to meet the mechanical, thermal, and operational demands of modern tile production and logistics.

Purpose-built bonding, not permanent adhesion

Roof tile spacer adhesives aren’t meant to glue tiles together. Their purpose is to create small, durable spacer points that hold surfaces apart during packaging and shipping—delivering dependable roof tile protection and reliable tile transport.

TECHNOMELT^® hotmelts are applied as precise adhesive dots onto the surface of each tile, usually on the underside or edges. Once cooled, the adhesive forms a solid, hard “pad” that resists compression but releases cleanly when the tiles are unpacked for installation.

This performance comes from the adhesive’s rheology, which  balance hardness, elasticity, and surface energy to control pad strength, separation, and clean release.

TECHNOMELT^® roof tile spacer adhesives are optimized for both clay and concrete tiles, each with distinct surface and weight characteristics, ensuring relable tile spacer performance.

Clay tiles

• Generally lighter, more porous
• Require adhesives with moderate flow and good surface wetting
• Typically lower application temperatures

Concrete tiles

• Heavier, denser, and smoother
• Demand high film hardness and superior compressive strength
• Adhesive dots must resist higher stacking loads

The versatility of TECHNOMELT^® formulations allows manufacturers to use a single adhesive grade across multiple tile product lines, reducing complexity and inventory.

Compared to traditional tile spacers like cardboard or foam, hotmelt spacers:

• Eliminate secondary materials (no interleaves or fillers)
• Reduce packaging volume
• Lower waste disposal costs
• Enable full recyclability of tile pallets

Energy and material savings

With optimized rheology and high bond efficiency, TECHNOMELT^® adhesives enable precise dot application at low coating weights (typically 0.1–0.3 g per tile), minimizing adhesive consumption while maintaining excellent roof tile protection.
