UV light-sensitive adhesives
DELO-DUALBOND® adhesives feature a dual curing system that ensures both the smooth running of a production process and the final strength of the assembly. The UV exposure process is the first curing system, allowing the positioning of the elements before handling. Subsequently, the final curing (heat or moisture) will allow a strong final assembly.
Technical data sheet
The DELO-DUALBOND® AD4950 adhesive has a double curing system, UV for positioning the parts before handling, and moisture for final curing. This adhesive is used for cosmetic applications in the bonding of perfume caps and allows the neutralization of the adhesive in an opaque area and prevents the odour of acrylic acid.
The DELO-DUALBOND® GE4910 adhesive has a dual curing system, UV for positioning the parts before handling, and moisture for final curing. This adhesive is used for automotive applications in the coating of micro switch connectors on EGR valves and has a temperature resistance of -40° + 160°.
DELO-DUALBOND® DB140 or DB180 adhesives feature a dual cure system, UV for pre-attachment of the sub-assembly and anaerobic for final cure. These adhesives can be used in complex environments for automotive applications such as water pump or car oil pan drain plug bonding. These adhesives are resistant to engine oils and chemicals.
DELO-DUALBOND® ML adhesives have a dual UV and anaerobic curing system. These adhesives are used for bonding applications in electric motors. Thanks to this family of DELO-DUALBOND® ML adhesives, which have many advantages such as high temperature resistance (+ 220°C), chemical resistance, very fast light fixation, the bonding of magnets to rotors or the bonding of stators is a feasible assembly operation.
All three dual-curing systems share the UV exposure process, which is the primary curing process for DELO-DUALBOND® adhesives. This UV exposure allows the elements to be positioned and/or held in place so that they can be handled quickly, in just a few seconds.
The final cure differs depending on the system:
DELO-DUALBOND® adhesives are one-component adhesives. They allow to gain in productivity and to replace certain two-component adhesives in one.
They have a better resistance to chemical aggressions, thanks to the double molecular network present within the same adhesive, as well as a resistance to temperature (from -40°C to +180°C).
>> HOW TO BOND ELECTRONIC SENSORS?The applications of DELO-DUALBOND® adhesives are diverse, depending on the curing system chosen.
The {UV + Anaerobic} bonding is found in metal bonding applications, ferrite bonding, e-motor assembly, …
For {UV + Humidity} bonding, we find applications of screen bonding, electronic components, but also bonding on glass, plastic or metal, allowing in particular to neutralize the adhesive on cosmetic packaging.
Finally, {UV + Thermal} bonding is found in applications requiring optical indexing, such as the bonding of camera lenses.
