SI Structural Adhesives





Tech-Bond’s Surface Insensitive (SI) Structural Cyanoacrylates (SCA) are stronger and more durable than over-the-counter super glues.  Our adhesives bond wood, metal, ceramics, leather, vinyl, plastics, rubber, carbon fiber, resins, pot metal, etc.  Using our patented Bonding Polymer Process, our SI adhesives will permanently bond polymers, co-polymers and polyolefins (poly-plastics)

SI Blue is our standard viscosity adhesive.  SI Black is a thicker viscosity providing more control.  SI Green is an ultra-thin SCA suitable for hairline cracks and wicking.  Our SI structural adhesives are guaranteed to have a shelf life of two years.  We recommending storing our SI adhesives in a refrigerator before using and between uses.
