LUMiFRAC ®
The LUMiFrac is the new benchmark for determining adhesive strength (winner of the Berlin-Brandenburg 2012 Innovation Award). It employs centrifugal forces to stress multiple samples at once. It provides adhesive and tensile strength as well as shear strength as an absolute physical quantity in N/mm² (MPa).
The LUMiFrac accomplishes this by directly applying an incrementally increasing centrifugal force to the specimen being tested. It determines with high resolution the RPM at the moment of fracturing (employing CAT-Technology = Centrifugal Adhesion Testing Technology).
Standardised short time measurements for QC.
- Testing of tensile strength of bonded joints:
– Cyanoacrylates
– Epoxy adhesives
– Polyurethanes
- Determination of adhesive strength of coatings:
– Anti-corrosion coatings
– Decorative coatings
– Metallized polymers
– Optical coatings
- Long-term fatigue testing:
– Alternating loads
– Different temperatures
