Vitralit® 7041 - 1

Vitralit® 7041 Product Description ® Vitralit 7041 is a low viscous, UV and visible light curing acrylate adhesive. Its colour is transparent to ® light yellowish, which does not affect the overall properties of Vitralit 7041. This adhesive is specially designed for plastic bonding. It provides excellent adhesion to PC, ABS or ® PET and shows very good adhesion to glass and metal. Vitralit 7041 is suitable for bonding transparent plastics with low UV transmission such as PC. ® Vitralit 7041 has met the requirements for USP Class VI/ISO 10993/-4/-5 and is suitable for the assembly of disposable medical devices. ® Its low viscosity makes Vitralit 7041 ideal for needle bonding and other medical applications where wicking of the adhesives into the pre-assembled parts is required. It is compatible with sterilization by autoclaving, gamma irradiation and EO. ® Vitralit 7041 is also available in a fluorescing version for optimum process control. Vitralit 7041 can be cured by exposure of UV and/or light. Increased cure properties are developed after 24 hours. Material with a thickness of 0.02 mm can be cured in approximately two seconds using UVA light with an intensity of 60 mW/cm². For rapid and high quality bonding we recommend the UV and LE-D devices manufactured by Dr. Hönle AG, which complement our adhesive technology. bluepoint LED/LED-Spot Wavelength [nm] + limited ++ suitable +++ excellent To obtain full cure at least one substrate must be transparent to UV and/or visible light. The speed of cure will depend upon light intensity, light source, exposure time, and the light transmittance of the substrate. The graphs below show the increase in depth of cure as a function of exposure time at two different intensities for two different curing devices.

Vitralit® 7041 Tensile Shear Strength [MPa] PE-Norm 013 Sterilization The diagram below shows the tensile shear strength of PC/PC bonding expressed as % from the initial value after sterilization. The adhesive was cured at 30 mW/cm². Vitralit 7041 shows excellent bond strength retention after autolaving, EO and gamma irradiation. In general, the resistance depends on the substrate, the curing parameters and the process of sterilization. It remains the user's obligation to determine the effect of sterilization on the specific procduct. Storage and Shelf life The product can be stored for 6...

Vitralit® 7041 Instructions for Use Surface Preparation The surfaces to be bonded should be clean and free from oil and grease. Slightly soiled surfaces can ® be cleaned with our cleaner IP . Substrates with low surface energy (such as polyethylene and polypropylene) need to be pretreated. Application Our products are supplied ready for use. They can be applied manually from the cartridges or automatically with air-operated dosing devices (cartridge/piston combination). Depending on the amount of adhesive to be used, different valves are availabe. If help is required, please consult our...
