Hot melt adhesives

For the wood and industry sector

Hot melt adhesives for the wood and industrial sectors

The hot melt adhesives They are solid at room temperature. The bonding process is activated with the product fusion, which comes inserted into a fuser, melted and applied via roller, nozzle or slot system.

Done thecoupling of materials and completed the Cooling phase, you get a precise, fast and durable bonding.

Based on the chemical composition, hot melt adhesives are divided into three large families:

  • Eva Base

    Hot melt adhesives traditional and easy to use, ideal for:

    • Edging
    • Covering of profiles with veneer, paper and laminates

    They present a good thermal resistance, up to approximately 80°C, and excellent workability.

  • Polyolefin Base

    Hot melt stickers with superior thermal resistances to the EVA municipalities (110°C – 130°C), used for:

    • Edging
    • Profile covering with paper and veneer

    Perfect for more demanding jobs that require superior stability and durability.

  • Pure Base

    Stickers new generation hot melt, used for:

    • Profile covering
    • Professional edging
    • Production of parquet and edges
    • Panel lamination

    Unlike the other two types (EVA base and polyolefin base), the PUR based hot melt adhesives (reactive polyurethanes) are distinguished by a double adhesion mechanism: after the Initial cooling, which guarantees an initial physical cohesion, the product continues to react on a chemical level thanks to the interaction with theenvironmental humidity and with that present in the glued materials, causing the rlabeling of resin molecules.

    This chemical process gives PUR adhesives:

      • Excellent thermal resistance (beyond 150°C)

      • Chemical stability even in the presence of solvents

      • High resistance in humid environments or in contact with water

    To make the most of their properties, PUR adhesives require dedicated machinery and a controlled application system.
