Solvent-Free. Smart. Sustainable.

TwinMelt® technology

Award-winning technology meets chemistry: with TwinMelt® Lohmann offers customized bonding solutions – 100 % solvent-free. Adhesive tapes produced with the innovative technology are based on acrylic and rubber systems, which offer various advantages. While both systems are biocompatible, acrylic systems provide low VOC values as well as a high chemical resistance and are especially suitable for direct and indirect food contact. Rubber systems provide the benefit of good adhesive properties (peel strength and tack) and are well-suited to low energy surfaces.

TwinMelt® makes multifunctional product designs and innovative combinations possible: with high material variance in carrier and liner systems and different chemistries, various tape constructions as well as symmetrical and asymmetrical stripe coatings can be realized in just one production step. This saves resources and allows for breathable adhesive coatings, from very low to very high application weights.

Sustainability at Lohmann.

Lohmann’s solvent-free TwinMelt® technology enables the sustainable production of double-sided adhesive tapes with great freedom of design. With 66 % lower energy consumption per square meter of adhesive tape, doubled production speed and powered by 100 % green electricity we significantly reduce the product-specific carbon footprint and support you in lowering the environmental impact of your production process.

The chemistry

Acrylic and rubber systems form the basis for TwinMelt® technology and enable solvent-free compounds. But they offer much more than that:

Characteristics Acrylic Systems Characteristics Rubber Systems
  • 100% solvent-free
  • Low VOC values
  • Clear and transparent
  • Biocompatible
  • Suitable for direct and indirect food contact
  • Sustainable and market-oriented
  • High chemical resistance
  • Exceptionally good adhesive properties in terms of peel strength and tack
  • Especially suitable for low energy surfaces
  • 100% solvent-free
  • Biocompatible
  • Sustainable and market-oriented

 

he TwinMelt® technology enables us to combine rubber systems and acrylic systems in a wide variety of structures.

The technology

The multifunctional TwinMelt® technology allows for double-sided adhesive tapes based on acrylic and rubber systems to be coated in a smart process – and 100% solvent-free.

Multifunctionality through

  • Combination of different chemistries and high material variance in carrier and liner systems
  • Coating of very low to very high application weights
  • Symmetrical and asymmetrical coatings

The possibilites

  • Coating width from 1,000 to 1,530 mm
  • Adhesive coatings of 20 - 600g / m² in compliance with tightest tolerances
  • Combination of different adhesives by means of innovative process technology allowing for asymmetrical designs
  • Optimized flatness by means of careful thermal material guiding

The benefits

  • Solvent-free coating process and reduced carbon footprint
  • Reduced energy consumption
  • Freely selectable placement of scrims and other materials in the adhesive layer (various carrier materials possible)
  • Tight thickness tolerance due to the uniform basis weight application
  • Two different chemistries can be combined in a smart processing step
  • New product combinations can now be realized that were previously impossible or difficult to achieve
  • Symmetrical and asymmetrical stripe coatings save material and allow for breathable adhesive coatings
