Adhesive sprays are among the easiest ways to bond all kinds of materials. Unfortunately, they've developed a bit of a reputation for not being that strong. This isn't always true. In this post, we present two of our strongest spray adhesives; one from 3M and one from Weicon Germany.

Why We Consider These Two to be Extra Strong Adhesive Sprays

3M 90 and Weicon Adhesive Spray Extra Strong Spray Adhesive CansOur Weicon Adhesive Spray Extra Strong and 3M 90 Hi-Strength Spray Adhesive are just two products in our adhesive spray range

They are also the two that exhibit the highest bond strength. This is due to their formulation. Both have a thick consistency that allows for high shear strength to the bonding surface and high tensile strength of the adhesive itself. 

Both are also quite versatile and can be used on a wide range of materials.

Both 3M 90 and Adhesive Spray Extra Strong can be used to bond...

  • Felt (decorative, polyester, aramid, engineering or industrial).
  • Solid rubber sheet (except for Silicone rubber)
  • Sponge rubber (again, except for silicone sponge)
  • Insulating materials (e.g. expanded insulation foam, high temperature cloth, electrical insulation papers)
  • Soft foam (such as PVC sponge)
  • Carpets (perfect for affixing carpet tiles)
  • Plastics (Most types. Known exceptions include polyethylene, PTFE and polypropylene).
  • Vinyl
  • Leather
  • Imitation leather
  • Metal
  • Wood
  • PVC foil
  • Paper and Carboard

3M #90 and Weicon Adhesive Spray Extra Strong Comparison.

In our experience, the 3M 90 Spray is a little thicker and goes on something like very sticky spiderwebs. The Adhesive Spray Extra Strong is a little more liquid at first, however once its been allowed to set (evaporation time) it has a similar consistency.

The table below gives a brief overview of some of the similarities and differences between these strong spray on glues.
