Examples of use
Flexible bonding for use in metalworking, equipment and machinery manufacturing, plastics, ventilation and air conditioning technology, as well as automotive, railcar, vehicle, and container construction. Rapid curing allows for quick further processing of the bonded parts. The neutral-curing polymer enables application without thermal or chemical pretreatment of the parts to be joined. Joints that compensate for dimensional tolerances.

Cure depth after 24h ≥ 3.5 mm Cure depth after 48h ≥ 4.5 mm Shore A hardness, DIN ISO 7619-1 50 Tensile strength, DIN 53504 S2* approx. 3.4 N/mm² Modulus at 100% elongation, DIN 53504 S2 * approx. 2.2 N/mm² Elongation at break, DIN 53504 S2 * approx. 200% Density 1.40 ± 0.05 g/cm³ Volume change, DIN EN ISO 10563 ≤ 7% Temperature resistance after curing -40 °C to +90 °C Processing temperature +5 °C to +40 °C All measurements were performed under standard conditions (23 °C and 50% relative humidity). * The data is based on measurements taken after 3 months. Application examples Flexible bonding in the fields of metal, apparatus, and mechanical engineering; plastics, ventilation, and air conditioning technology; and body, railcar, vehicle, and container construction. Rapid cross-linking allows for quick further processing of the bonded parts. The neutral-curing polymer allows for application without thermal or chemical pretreatment of the jointed part. Tolerance-compensating bond. Adhesion spectrum: Well-suited materials include metals, powder-coated, painted, galvanized, anodized, chromated, or hot-dip galvanized surfaces, various plastics, ceramics, stone, concrete, and wood. Due to the wide variety of different plastics and compositions, as well as materials prone to stress cracking, preliminary tests are recommended. Compatible with polystyrene (EPS/XPS).
