TECHNICAL SHEET • HIGH RESISTANT • HIGH VISCOSITY • YELLOWISH COLOR WITH FLUORESCENT AZURANT • LIGHT CURING & ANAEROBIC CURING KEOL-UV 291 KEOL-UV 291 is a high viscosity light, heat and activator curing anaerobic adhesive. Suitable for metal voltage equalization connections, for fastening: coaxial components, eg bearings or bushings. Also suitable for bonding components with different coefficients of expansion. Curing can be aided by heat, or the use of an activator and/or UV light (wavelength range 320-450 nm). KEOL-UV 291 complies with the directive RoHS2015/863/EU. CHEMICAL BASIS Clear yellowish Chemical basis Modified urethane acrylate Clear yellowish with fluorescent azurant Color Viscosity @23°C BrookfieldmPas Curing time to initial strength [min] at room temperature (approx. 23°C), anaerobic on zinc phosphated screws Minimum irradiation time (s) UVA intensity: 60mW/cm2 Shear strength by compression Glass/Glass MPa wavelength 400nm Intensity 200mW/cm2 Compressive shear strength Stainless steel /PA MPa wavelength 400nm Intensity 200mW/cm2 Glass transition temperature (TG) in °C Shelf life at room temperature From 0°C to +25°C in the original unopened container Shelf life in unopened container Up to 600ml at room temperature (0 to +10°C)

TECHNICAL SHEET SURFACE PREPARATION The surfaces to be bonded must be dry and free from dust, grease and other contamination.
