Reactive adhesives
The combination of the advantages of two adhesive worlds: Polyurethane hot-melt adhesives combine the advantages of physically setting hot-melt adhesives with those of reactive one/two component adhesives. High processing speeds and high adhesive strength combined in one product allow high-strength, constructive bonding. They are always used when exceptionally high temperature resistance is to be achieved while, at the same time, having good flexibility at low temperatures and resistance to a wide range of chemicals. The bonds have a high resistance to aging in products with a long service life. Standard PUR hot melts with an MDI content >0.1% are subject to labelling.
You can process the adhesive manually in small cartridges or in automated processes with drums of up to 200 kg. Close advice and support from our laboratory and technical team helps with choice of the right adhesive, substrate and process design. We would be glad to assist you if you have any questions regarding occupational safety when dealing with reactive hot-melt adhesives.
Your advantages when using reactive PUR / POR products:
High cohesion enables constructive bonds
High temperature resistance in the cold as well as in the heat enable, for example, use in the automotive industry
Resistance to plasticizers, oils and solvents enables the bonding of soft PVC and demanding filter applications
High level of ageing stability of the bond
PUR have a very wide adhesion spectrum to many plastics, for instance ABS
POR offer a very good adhesion spectrum to low-energy surfaces, for example PP
