UV 165-183: One Component, Fire Resistant UV

Product Description

UV 165-183 is a fast curing urethane acrylate that bonds well to a wide variety of different substrates. This product requires direct UV exposure during cure. The ability of this product to fluoresce under black light facilitates inspection of bonded assemblies for adhesive presence. Because of the variability of different UV light sources, it is suggested that the user test and specify UV intensity and exposure time. This product will cure in the presence of UV/Visible light as defined in the cure recommendations below. UV 165-183 has passed UL94 V0 (UL file: E105698) standards for flame resistance. The adhesive is in full compliance with RoHS Directive 2011/65/EU and RoHS Directive EU 2015/863.
