Useful Information

Solvent-based or hot melt? We gathered what the two technologies mean in day-to-day production: odour, consumption per m², application temperature, solid content and packaging.

DIFFERENCE

Solvent-Based or Hot Melt?

VERA VR SERIES

Solvent-Based Adhesives

  • OdourContains solvent, so there is a noticeable odour during application; work in a well-ventilated area.
  • Consumption per m²Approximately 150 g/m² in mattress applications.
  • ApplicationAt room temperature, sprayed onto both surfaces at a 45° angle.
  • Solid content39 – 51% (by product); the rest is solvent that evaporates while drying.
  • DryingBoth sides 0–6 / 0–10 min; heat resistance 55–75 °C.
  • Packaging4 / 14 / 15 kg tin cans, 225 kg drums, 1200 kg IBC tanks.

VERAMELT SH SERIES

Hot Melt Adhesives

  • OdourOdourless; contains no solvent.
  • Consumption per m²Approximately 17 – 20 g/m² in mattress applications.
  • ApplicationWith a hot melt spray gun at 140 – 170 °C; open time 0–3 min.
  • Solid content100%; every gram applied stays on the surface.
  • Softening point85 – 100 °C (by product); can be heat-reactivated.
  • PackagingApprox. 9 kg cardboard boxes, in blocks; the bond can be reopened with heat (recycling).

TIPS

Storage and Handling Tips

Key notes from our brochures.

Solvent-based storage

Stored in its unopened original packaging at about 20 °C and properly closed, it keeps for 12 months without a change in viscosity.

Hot melt storage

Keep in a cool, dry place, preferably between 10 and 30 °C; keep away from heat sources and close the box lids after use.

Polyurethane surfaces

Roughen the polyurethane surface with a metal brush before bonding to remove silicone and oil.

Choosing the right product

The product changes with the surface pair, line speed and expected performance. See the Applications page for our recommendations by application.
