Common Questions and Answers about Cyanoacrylate Super Glue Adhesives

What is super glue viscosity?

The viscosity of a cyanoacrylate super glue refers to the thickness of the adhesive and is usually referenced in centipoise (cps). Thinner super glues are good for getting into tight places and covering substrates while thicker super glues can help with gap filling. Below is a brief reference for viscosity.

  • 1-5 cps: like water
  • 50 to 100 cps: like motor oil
  • 2,500 cps: like honey
  • 50,000 cps: like Ketchup

What are surface insensitive (SI) cyanoacrylate super glues?

Surface insensitive cyanoacrylates are formulated for extremely fast curing, even by super glue standards. They also bond to a wide range of surfaces including wood, plastics, metals and glass. Surface Insensitive super glue adhesives are one of our favorite choices for general purpose use because of their set speed, strength and versatility.

What is toughened super glue?

Toughened super glue, sometimes called rubber toughened, is formulated to offer impact and shock resistance. Toughened cyanoacrylates typically have a more flexible bond and hold up under high and low temperatures. They are also often better for outdoor conditions when exposed to a lot of moisture or humidity.

What are cyanoacrylate super glue accelerators?

Cyanoacrylate accelerators can be applied on substrates before super glue is applied, or in some cases afterwards, to make the adhesive cure faster. These are particularly useful for substrates that are hard to hold in place, high volume applications or with cyanoacrylates that have slower set times (like toughened super glues).
