Acrylic UV Adhesive

UV adhesives based on acrylic resin from Panacol-USA can be used in a very wide range of industrial applications for the purpose of bonding, sealing, masking, and coating of components and assemblies. These single component formulations are solvent-free, and fully cure (harden) in seconds when exposed to ultraviolet (UV) or visible light energy. 

Acrylic uv adhesives are comprised of three primary components: photoinitiator, monomer, and oligomer (resin). The photoinitiator triggers the curing process when it is exposed to light energy of the appropriate wavelength. The monomer component in the formulation primarily impacts the degree of adhesion to any given substrate. The oligomer provides most of the post-cure mechanical properties such as hardness, elongation, elasticity, shrinkage, etc. Small percentages of additives may also be incorporated into the formulations to provide unique features such as fluorescence and color. Specially formulated acrylic adhesives from Panacol-USA feature thermal or moisture postcuring, ensuring fully cured adhesives in shadowed areas.

Panacol-USA’s light curable adhesives are based on either acrylate or epoxy resin. Read more about our epoxy-based adhesives.

UV Curable Acrylic Adhesives

Creativity and technical expertise drive Panacol-USA R&D chemists to develop truly unique uv adhesive technology. These include:

  • UV adhesives: Multi-purpose adhesives and coating that cure rapidly when exposed to UV light energy (less than 395nm).
  • UV/Visible light curable adhesives: Adhesive that absorb the broad UV and visible light spectrum for faster and deeper curing. Ideally suited for substrates that partially or fully block UV wavelengths.
  • Visible light curable adhesives: Formulated to cure with only visible light (400-420nm). Unique formulations can also be produced with curing ability at 455-465nm wavelengths.
  • LED curable adhesives: Adhesives that cure with monochromatic LED systems, with preferred wavelengths of 365nm or 405nm.

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 include 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.

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. Panacol-USA has been formulating low intensity light curable adhesives for over 15 years. This experience was instrumental in the development of our LED curable product line. When combined with the appropriate LED light source, Panacol-USA LED curable adhesives and sealants deliver all the efficiencies and benefits expected from LED curing.
