LEDcure UV Adhesives

LED light sources are slowly making inroads into all markets for the specific purpose of curing (hardening) industrial light curable adhesives and sealants. Equipment manufacturers are now offering higher output intensities with greater selections of wavelength options in both the UV and Visible light regions. The advantages of LED curing includes cooler curing temperatures, instant on/off control without shutter mechanisms, and long operating life.

Typically described as monochromatic, LED curing is unique. Although it is identified by only a single output wavelength, the actual energy produced is a very concentrated cluster of wavelengths that includes the specified wavelength and those immediately adjacent to that wavelength. Unlike traditional broad spectrum mercury based systems, LED outputs are typically lower in intensity and narrow in spectral distribution.

The adhesive and sealant market is saturated with claims of LED curable adhesives. Unfortunately for the users, not all will work as expected. With many of these adhesives, typical cure times can double or triple. The cured adhesive may not develop the same cured properties as when using traditional broad spectrum UV equipment.

A successful LED cure bonding process requires the pairing LED equipment with adhesives and sealants that are specifically formulated for lower intensity, isolated wavelength curing. Tangent Industries has been formulating low intensity light curable adhesives for over 15 years. This experience was instrumental in the development of our LEDcure product line. When combined with the appropriate LED light source, Tangent LEDcure adhesives and sealants deliver all the efficiencies and benefits expected from LED curing.

From the directory below, you will find LEDcure adhesives and sealants that can be used in various applications and industries. Their common link is that all are fully curable with LED curing equipment that produces a UVA or Visible Light wavelength (315-450nm). Utilizing LED curing equipment that produces a wavelength in the visible spectrum (e.g. 385 or 400nm) will typically increase depth of adhesive cure, and permit curing through UV inhibiting substrates. Of course, all Tangent LEDcure adhesives and sealants may be cured using traditional broad spectrum UV curing equipment.

Please contact Tangent to confirm your product selection and to secure additional application assistance, including samples and process recommendations. In the event that these standard products do not satisfactorily address your performance requirements, Tangent will investigate other solutions that include development of adhesive specifically tailored to the complexity of your application.
