Description

B350 Structural UV Glass Bonder is a highly reactive urethane methacrylate resin that is designed for all types of glass bonding which can be cured by UV light.  The liquid is highly reactive to UV forming glass to glass or glass to metal bonds in seconds.  B350 Structural is also resistant to ageing once cured, exhibiting excellent strengths retention properties and resists the action of yellowing during long term exposure to the elements.

UV365N is needed to cure B350. Some lamps provide a second cure at lower wavelengths which assist the cure. Heat is generated by some high intensity (high powered) lamps.  This can cause problems by over exposure and increased reactivity in the resin, building up excessive heat or stress. Ideal conditions can be provided by optimising some of the work parameters.  Low intensity lamps will give a slower cure and take longer to cure big gaps.

Examples are as follows for UV B350.
