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.
Approximate consumption per m² in mattress applications.
Same criteria, two technologies.
| Property | Solvent-Based (VR) | Hot Melt (Veramelt SH) |
|---|---|---|
| Odour | Yes | None |
| Consumption (mattress, approx.) | 150 g/m² | 17 – 20 g/m² |
| Solid content | 39 – 51% | 100% |
| Application temperature | Room temperature | 140 – 170 °C |
| Application method | Spray gun (both surfaces) | Hot melt spray gun |
| Drying / open time | 0–6 / 0–10 min (both sides) | 0–3 min open time |
| Heat resistance / softening | 55 – 75 °C | 85 – 100 °C softening point |
| Re-activation | — | Can be heat-reactivated |
| Packaging | Tin can · Drum · IBC | Approx. 9 kg cardboard box |

Same job, two technologies: solvent-based spray application on the left, hot melt on the right.
Key notes from our brochures.
Stored in its unopened original packaging at about 20 °C and properly closed, it keeps for 12 months without a change in viscosity.
Keep in a cool, dry place, preferably between 10 and 30 °C; keep away from heat sources and close the box lids after use.
Roughen the polyurethane surface with a metal brush before bonding to remove silicone and oil.
The product changes with the surface pair, line speed and expected performance. See the Applications page for our recommendations by application.
