1C and 2C PUR adhesives
They are liquid, chemically setting adhesives that provide excellent bonding to different material combinations and extremely strong resistance to temperatures and water. The choice of which product to use generally depends on the manufacturing process and the intended purpose of the end products. Our 1C and 2C PUR adhesives can be formulated to individual needs and specifications, resulting in customized and effective production processes all along the line. The following properties underline the strengths of these adhesives:
- available with different open times
- good bonding even of complex material combinations, such as wood, mineral and ceramic materials, and plastic composites
- high resistance to chemicals
- excellent resistance to heat and cold
- available as foaming and non-foaming compact systems

One-component PUR adhesives react with the moisture in the air and on the carrier material (if present) and/or with the functional groups on the surfaces to be bonded.

Two-component PUR systems do not require moisture. Instead, a chemical reaction is induced by the targeted addition of a suitable hardener, which also enables a precisely timed curing process. These adhesives can also form a chemical bond with functional groups on the surfaces to be bonded.
