Hotmelt Slot Die System

Function/Description

Hotmelts are thermoplastic adhesives, based on polymers, that soften plastically at temperatures between 80°C and 220°C and harden if they are cooled.

• 100% dry substance, no dilution
• are applicated in a liquid state
• easy metering
• bonds quickly
• short laminating distances and linking times

With slot dies, products are applicated as 2-dimensional, closed films. They can be used for continuous coatings with a viscosity range of 50 to 250 000 mPas. In combination with the adequate "mask" the coating weight and wideness can be determined: If a closed film is applicated > 10 g/m², in case of partially porous films < 10 g/m².

The coating weight is determined by the performance of the pump, the web speed and the distance between the die and the substrate.
