Adhesives

Spectra Group has developed a number of specialty adhesives. Most adhesives manufactured  are unique optimized specialty use products. Among the products developed by Spectra Group there are one-part light curable (UV/Vis)adhesives for various plastic substrates and a series of structural two-part epoxy-amine adhesives for metals and alloys.

 

 

Adhesives

Spectra Group offers:

  • one component UV/Vis curable adhesives (both free radical AND cationic), mostly for plastics
  • two-component blends for metals and alloys

Plastic substrates include:

  • Polycarbonate
  • Acrylic
  • Polypropylene
  • Polypropylene-to-Paper
  • Polyvinyl Chloride (PVC)
  • Polylactic Acid (PLA)

If we do not have an off-the-shelf solution, our goal is to Custom Formulate one to fit your specification.Contact us for more information.
