Reaktive PUR-Schmelzklebstoffe

Reactive hotmelts are mainly used in industrial gluing processes, but increasingly also in skilled craft businesses. They enable extremely strong adhesive bonds and customized processes. No other adhesive system offers such a high degree of customizability. Reactive PUR hotmelts have gone through major developments over the past decades and are being used for more applications every day. There are practically no limits to their uses. In fact, applications that seem unimaginable today may well be realized with PUR hotmelts tomorrow.  

Reactive PUR hotmelts are solid masses that are melted and applied while still fluid. The bonding strength is then consolidated in an ensuing two-stage physical-chemical process.

1. Physical

After the adhesive has been applied, it cools off and solidifies, leading to high to very high initial strength.

2. Chemical

The next step involves a chemically reactive hardening process. The adhesive reacts with the moisture either on or in the material to be bonded and with the moisture in the air. This results in a tightly cross-linked elastomer with mechanical properties ranging from highly elastic to highly rigid, depending on the formulation, that permanently bonds the materials. Once the reaction is completed, the adhesive cannot be remelted. The timing of the chemical reaction can be defined in the adhesive formulation, depending on the field of use.

In some cases, if the material to be bonded is suitable, the hotmelt adhesive also reacts with the material’s solid components, leading not only to physical bonds, but to inseparable chemical bonds at atom level. This results in absolutely top-quality bonding. The adhesive properties and water and temperature resistance of reactive PUR hotmelts are hard to beat.

Low-emission, reactive PUR hotmelts (micro-emission, ME)

Demand for low-emission adhesive systems has risen sharply in recent years. ME adhesives are a good entry product into the world of reactive hotmelts. As hazard substance labelling no longer applies to them, they, like EVA and PO hotmelts, can be used for extraction and filter systems. Having identical adhesive properties to standard PUR hotmelts, ME hotmelts provide for safer and more environmentally-friendly manufacturing processes all along the line.

Our chemical engineers have been developing low-emission hotmelts for many years and can customize ME hotmelts for very specific uses – for the furniture industry, the building industry, the automobile sector, for filters, textiles, and much more. Nothing is impossible!

To the products

Bio-based reactive PUR hotmelts

PUR adhesive systems based on sustainable, plant-based raw materials are becoming increasingly popular. The prerequisite is that the plant-based raw materials used are not suitable for food production. KLEIBERIT’s bio-based PUR hotmelts achieve exactly the same bonding results as the established PUR hotmelts.
